EMV Sale​

On-device · chip, contactless, or magstripeCloud APIAndroid (PAX)Android (HiLite)iOS (HiLite)CordovaJavaScript SDKWindows (.NET)

Standard chip or contactless card-present payment — the cardholder taps, inserts, or swipes their card at the terminal. The terminal handles card entry mode automatically.

When to use it​

Use for standard retail and hospitality transactions where the cardholder is physically present and the amount is fixed before checkout. For a final amount that may change after authorisation (e.g. restaurant tab), use Pre-Authorization instead.

Code​

POST https://cloud.handpoint.com/transactions
ApiKeyCloud: YOUR_MERCHANT_API_KEY
Content-Type: application/json

  "customerReference": "order-5248",
  "transactionReference": "2bfde1fc-23b1-4c67-93d9-1d4a557f4d4f"
}

Amount is in the smallest currency unit — "1000" = $10.00 USD. The 202 response returns a transactionResultId — poll GET /transaction-result/{transactionResultId} on cloud.handpoint.com for the outcome. Your transactionReference UUID v4 can also be used to query the full operation chain via GET /transactions/{transactionReference}/status/all on transactions.handpoint.com.

Key Entry Sale​

On-device · operator keys card numberCloud APIAndroid (PAX)JavaScript SDKWindows (.NET)

Commands a PAX terminal to display a manual card entry screen — the cashier types the cardholder's card number, expiry, and CVV directly on the terminal's touchscreen. The terminal tokenizes the entry internally and processes it as a MOTO transaction. The ISV system never handles raw card data.

Processed as MOTO — acquirer fees apply

Despite using a physical PAX terminal, Key Entry Sale is submitted to the acquirer as a MOTO (card-not-present) transaction, not as a card-present key-entry transaction. This is because the card is manually entered rather than electronically read. MOTO transactions typically carry higher interchange rates than card-present transactions. Confirm the fee structure with your acquirer during merchant onboarding.

When to use it​

Use for phone orders where the cardholder reads their card details aloud to a call centre agent, or in-person situations where the card cannot be read electronically. The PAX terminal must be present in your environment and running in integrated mode.

Card data stays on the terminal

Unlike back-office MOTO (which uses a stored card token), key entry sale requires the PAX terminal to be physically present. The operator's system sends the command; the terminal's screen collects the card details.

Code​

POST https://cloud.handpoint.com/transactions
ApiKeyCloud: YOUR_MERCHANT_API_KEY
Content-Type: application/json

{
  "operation": "moToSale",
  "amount": "1000",
  "currency": "USD",

  "serial_number": "082104578",
  "transactionReference": "2bfde1fc-23b1-4c67-93d9-1d4a557f4d4f"
}

Amount in smallest currency unit. The terminal shows a card entry screen — the operator types card details on device.

Address Verification (AVS)​

TSYS supports optional Address Verification on Key Entry Sale. The terminal can prompt for the cardholder's billing postal code after card entry, or you can pass it programmatically.

// Option A — terminal prompts for zip code after card details are entered
val options = MoToOptions(enableAvsFields = true)
hapi.motoSale(BigInteger("1000"), Currency.USD, options)

// Option B — supply billing data from your own UI
val billing = Billing(zipCode = "10001", address = "123 Main St")
val options = MoToOptions(billing = billing)
hapi.motoSale(BigInteger("1000"), Currency.USD, options)

Do not combine enableAvsFields with billing — they are mutually exclusive. Requires avsForMoto and motoEnabled = true (both set per merchant by Handpoint).

Remote Sale (MOTO)​

Back-office · charges a stored card tokenAndroid (PAX)CordovaBackoffice

A card-not-present sale submitted directly to the gateway using a stored card token — no terminal or card reader required. The ISV system sends the charge via REST API or Android SDK using a token previously issued by a supported token provider.

When to use it​

Use for recurring billing, subscription charges, or any scenario where you hold a card-on-file token from a prior tokenization or card-present transaction. A card token must already exist before this operation can be sent.

How to obtain a card token​

MethodHowWhen to use
Sale & Tokenize (saleAndTokenizeCard)Charges the card and issues a token in one stepOnly when getting the token alongside the sale is a hard requirement — if the tokenization step fails, the entire authorisation also fails
Tokenize Only (tokenizeCard)No charge — reads the card and stores a tokenLoyalty enrolment, "save my card" flows, or any time you need a token without a payment
Deferred — GET token after sale (recommended)Do a regular sale, then call GET /transactions/{id}/token (Backoffice REST, no terminal needed)Preferred for recurring billing — decouples the token from the sale; a tokenisation failure doesn't affect the transaction result

The deferred approach is recommended because the card-present sale completes independently. You call the backoffice token endpoint afterwards and store the token for future card-not-present charges.

No raw card data — tokens only

Handpoint back-office MOTO does not accept raw PAN, expiry, or CVV from the ISV. All charges use a cardToken issued by a supported provider (e.g. Paysafe, Tokenex). The token provider de-tokenizes at processing time — the ISV never handles card data.

Address Verification (AVS)​

TSYS supports an optional billing object on MOTO Sale — postal code (and optionally street address) are forwarded to the acquirer to reduce CNP fraud risk. Requires avsForMoto enabled per merchant by Handpoint.

POST https://cloud.handpoint.com/moto/sale
ApiKeyCloud: YOUR_MERCHANT_API_KEY
Content-Type: application/json

  "billing": {
    "zipCode": "10001",
    "address": "123 Main St"

Sale with Tip​

On-device · tip collected at checkoutCloud APIAndroid (PAX)Android (HiLite)CordovaJavaScript SDKWindows (.NET)

Configure a tip prompt on the terminal as part of the sale — the cardholder selects a tip amount before completing payment. This is distinct from Tip Adjustment (which adds a tip after the sale is authorised).

When to use it​

Use in hospitality environments (restaurants, taxis, salons) where tipping is expected at point of sale. The tip is collected at the terminal, included in the authorised amount, and settled together with the base sale — no second operation is needed.

Code​

POST https://cloud.handpoint.com/transactions
ApiKeyCloud: YOUR_MERCHANT_API_KEY
Content-Type: application/json

{
  "operation": "sale",
  "amount": "1000",
  "currency": "USD",
  "terminal_type": "PAXA920",
  "serial_number": "082104578",
  "tipConfiguration": {
    "baseAmount": "1000",
    "tipPercentages": [10, 15, 20],
    "enterAmountEnabled": true,
    "skipEnabled": true,
    "footer": "Thank you!"
  },
  "transactionReference": "2bfde1fc-23b1-4c67-93d9-1d4a557f4d4f"
}

baseAmount is used to calculate the percentage amounts displayed. enterAmountEnabled: true lets the cardholder type a custom tip. skipEnabled: true adds a "No tip" option.

TipConfiguration fields​

FieldTypeDescription
baseAmountstring / BigIntegerBase sale amount used to calculate percentage tip values shown on screen
tipPercentagesarray of integersTip percentage options to display, e.g. [10, 15, 20]
enterAmountEnabledbooleantrue to show a "Custom amount" entry option
skipEnabledbooleantrue to show a "No tip / Skip" option
footerstringOptional message shown at the bottom of the tip screen

Result fields​

FieldDescription
tipAmountTip amount chosen by the cardholder (minor units)
totalAmountBase amount + tip — what was authorised and will settle

Pre-selected tip (ISV-collected)​

Use this variant when your application has already collected the tip from the cardholder — for example, your POS shows a custom tip screen and the cardholder selects a tip amount before the card is presented. Pass TipConfiguration(tipAmount) with the pre-determined amount; the terminal skips its own tip-selection screen and charges base + tip in a single authorisation.

POST https://cloud.handpoint.com/transactions
ApiKeyCloud: YOUR_MERCHANT_API_KEY
Content-Type: application/json

{
  "operation": "sale",
  "amount": "1000",
  "currency": "USD",
  "terminal_type": "PAXA920",

    "tipAmount": "500"
  },
  "transactionReference": "2bfde1fc-23b1-4c67-93d9-1d4a557f4d4f"
}

The terminal charges amount + tipAmount in a single authorisation. No tip-selection screen is shown on the terminal.

Tip Adjustment vs Sale with Tip

Sale with Tip collects the tip at the terminal before authorisation — the total (base + tip) is authorised in one step. Tip Adjustment adds a tip after an already-authorised sale, updating the settlement amount. Use Sale with Tip when the cardholder is at the terminal; use Tip Adjustment for tip-at-table flows where you capture a signature and enter the tip later.

Sale with Tokenization​

On-device · stores card token for future chargesCloud APIAndroid (PAX)Android (HiLite)iOS (HiLite)CordovaJavaScript SDKWindows (.NET)

Store a reusable card token during the sale so future card-not-present charges can be made without the cardholder being present again. The token is returned in the TransactionResult and can be used for subsequent back-office MOTO sales.

When to use it​

Use when onboarding a new customer in person — take the first payment as a normal card-present sale and simultaneously capture a card token for future recurring charges, subscriptions, or card-on-file billing.

Code​

Tokenization happens as a separate operation via the /transactions endpoint with "operation": "tokenizeCard". The resulting token can then be used in back-office MOTO sales.

POST https://cloud.handpoint.com/transactions
ApiKeyCloud: YOUR_MERCHANT_API_KEY
Content-Type: application/json

{
  "operation": "tokenizeCard",
  "currency": "USD",
  "terminal_type": "PAXA920",
  "serial_number": "082104578",
  "transactionReference": "2bfde1fc-23b1-4c67-93d9-1d4a557f4d4f"
}

The token is returned in the TransactionResult.cardToken field. Store it and use it in subsequent POST /moto/sale requests.

Result fields​

FieldDescription
cardTokenOpaque token string issued by the acquirer's token provider. Store this — do not log or expose it.
finStatusAUTHORISED on success

Using the token for future charges​

Pass cardToken in the Remote Sale (MOTO) flavor's cardToken field for subsequent card-not-present charges.

Token scope

Tokens are specific to the merchant and acquirer configuration. A token issued on a test/staging merchant cannot be used on production, and vice versa. Token validity periods vary by acquirer — consult your acquirer documentation.

Refund​

EMV Refund​

On-device · card present at terminalCloud APIAndroid (PAX)Android (HiLite)iOS (HiLite)CordovaJavaScript SDKWindows (.NET)

Returns funds to a cardholder's account for a card-present transaction. The cardholder must present their payment method at the terminal.

Linked refund (recommended): includes originalTransactionId — the gateway validates the original transaction and caps the refund at the original amount. Include partial amounts for partial refunds.

Unlinked refund: omit originalTransactionId — sends a standalone credit without referencing the original sale. Some acquirers restrict unlinked refunds; check your acquirer agreement.

Same payment method

Per merchant configuration, the same card used in the original sale must be presented. Physical card inserts and mobile wallet taps (Apple Pay, Google Pay) produce different PAN tokens — if same-card verification is enabled and the original sale was a physical insert, a wallet tap at refund time will decline. Advise the cardholder to use the same payment method they used at purchase.

When to use it​

Use for returns after settlement has occurred. For cancellations of unsettled transactions, use Reversal — it is faster and incurs no interchange fees.

Remote Refund (MOTO)​

Back-office · linked to original MOTO saleAndroid (PAX)CordovaJavaScript SDKWindows (.NET)Backoffice

A card-not-present refund submitted directly to the gateway — no terminal or card reader required. References the original MOTO sale by its GUID. Valid up to 12 months after the original sale date.

When to use it​

Use to refund a previously processed back-office MOTO or key-entry sale. The cardholder does not need to be present or provide their card again — the gateway retrieves the card from the original transaction.

Code​

Synchronous — the result is returned immediately. No terminal, no polling.

Key Entry Refund​

On-device · operator keys card numberCloud APIAndroid (PAX)JavaScript SDKWindows (.NET)

Commands a PAX terminal to display a manual card entry screen — the cashier types the cardholder's card number, expiry, and CVV directly on the terminal's touchscreen. The terminal processes the refund as a MOTO transaction. No original transaction ID required.

Processed as MOTO — acquirer fees apply

Key Entry Refund is submitted to the acquirer as a MOTO (card-not-present) transaction. MOTO transactions typically carry higher interchange rates. Confirm the fee structure with your acquirer during merchant onboarding.

Card data stays on the terminal

Unlike back-office MOTO refund (which uses a stored card token), key entry refund requires the PAX terminal to be physically present. The operator's system sends the command; the terminal's screen collects the card details.

When to use it​

Use when a cardholder requests a refund for a key-entry or phone order, and you do not have a stored card token. The PAX terminal must be present and running in integrated mode.

Code​

Reversal​

Reversal​

On-device · no card requiredCloud APIAndroid (PAX)Android (HiLite)iOS (HiLite)CordovaJavaScript SDKWindows (.NET)

What this does​

Cancels an unsettled transaction before batch settlement — the full authorised amount is released to the cardholder without interchange fees. No card present required.

When to use it​

Use when a transaction needs to be cancelled before the batch closes (same business day, before cut-off time). This is always preferable to a post-settlement Refund — faster and fee-free. Do NOT use after settlement — send a Refund instead.

Implementation notes​

  1. Same business day only. Reversal works on the current open batch only. Once the batch closes (cut-off time, typically end of business day), the transaction settles and only a post-settlement Refund is available.
  2. No card present required. Reversal references the original transactionID electronically — the cardholder does not need to return to the terminal.
  3. Terminal must be online. The SDK paths route the reversal through the connected reader — the terminal must be reachable at the time of the call.

Code​

Routes through the connected terminal SDK — the reversal is processed by the device and appears in the device app transaction history. Asynchronous — poll GET /transaction-result/{transactionResultId} for the outcome. Amount in minor units.

Response:

  "transactionResultId": "0821599465-1786020446467"
}

Partial Reversal​

What this does​

Reduces the authorised amount on a sale before settlement — the cardholder is charged only the reduced amount.

When to use it​

Use when the final amount is lower than the authorised amount and the batch is still open. Example: a pre-authorised $100 hotel stay costs only $80 at checkout. Do NOT attempt on closed batches — send a Refund instead.

Implementation notes​

  1. Requires TMS enablement per merchant. Contact your Handpoint integration engineer to enable partial reversal for a specific merchant account.
  2. The partial reversal uses the MasterCard flag in ISO 8583 internally.
  3. The result is non-cumulative — you cannot chain multiple partial reversals. The amount you send is the new final authorised amount, not a delta.
  4. Available via Cloud API and Android SDK (PAX). Not supported on HiLite or iOS paths.

Remote Reversal​

Back-office · no reader requiredCloud APIBackoffice
Cloud API vs. Backoffice — what's the difference?
PathHow it worksTransaction history
Cloud APIRoutes through the connected terminal SDK — the device processes the reversalAppears in device app transaction history
BackofficeSends directly to the payment gateway — no terminal or SDK involvedAppears in your POS/solution only — not in the device app

Both paths use the same ApiKeyCloud credential.

What this does​

Cancels any unsettled transaction — sale, MOTO, pre-auth capture, or refund — without the cardholder returning to the terminal.

When to use it​

  • Cloud API path: Use when you have a terminal online and want the reversal recorded in the device transaction history.
  • Backoffice path: Use when the terminal is unavailable, or when the original transaction was fully server-side (MOTO, pre-auth via Cloud API). No MOTO or TMS enablement required for full reversals.

Implementation notes​

  1. Backoffice amount is in major units (decimal string) — e.g. "11.00" for $11.00. Cloud API uses minor units (integer string).
  2. Omit amount and currency for a full reversal. Include them only for a partial reversal (EPI only — requires TMS enablement per merchant).
  3. Do NOT include a transactionReference on either path — this is a subsequent operation linked to the original.
  4. Interac cards (Paysafe + Interac gateway only): Remote reversal is not available for Interac card transactions. Interac requires card-present at terminal. Use the on-device Reversal flow instead. Non-Interac cards on the same gateway work normally.

Code​

Routes through the connected terminal SDK. Asynchronous — poll GET /transaction-result/{transactionResultId} for the outcome. The reversal appears in the device app transaction history.

Tip Adjustment​

Post-authorization · adjust tip before batch closeAndroid (PAX)Android (HiLite)CordovaBackoffice

Modifies the tip amount on a completed sale before batch close. Used in restaurant/hospitality flows where the cardholder signs a paper receipt and adds a tip after the initial authorization.

Full guide

For acquirer restrictions, batch-close deadline, cross-SDK usage, iOS HiLite specifics, and the Sale with Tip vs Tip Adjustment comparison, see the Tipping Guide.

Tip adjustment + partial refund ordering

If you need to perform a partial refund on a transaction that already has a tip adjustment, follow this sequence:

  1. Send a $0 tip adjustment to zero out the existing tip
  2. Perform the partial refund
  3. Send a new tip adjustment for the correct tip amount on the remaining balance

Why: This acquirer's backend links the tip to the original authorization amount. A partial refund against a tipped transaction can produce incorrect settlement figures unless the tip is zeroed first. Sending a new tip adjustment after the refund restores the correct tip on the adjusted balance.

TSYS

TSYS. Batch auto-closes ~11pm EST (host-capture). Partial reversal available for US and Canada — uses the MasterCard flag in ISO 8583. Tip adjustment only available on transactions processed without an on-screen tip (tip-at-table flow).

Code​

Synchronous — the gateway responds immediately. No terminal, no polling.

Pre-Authorization​

Pre-Auth Create​

On-device · chip, contactless, or magstripeCloud APIAndroid (PAX)CordovaJavaScript SDKWindows (.NET)

What this does​

Places a hold on funds without capturing them, allowing the final amount to be adjusted before settlement.

When to use it​

Use for hotel check-ins, car rentals, or any flow where the final amount is unknown at the time of card interaction. Do NOT use for standard retail — use Sale instead.

Pre-Auth is a bundle of operations​

Supporting pre-auth means supporting the full lifecycle:

OperationDescription
CreatePlace the initial hold
Increase / DecreaseAdjust the held amount before capture — see the Pre-Authorization Guide
CaptureFinalise and charge the held amount
Pre-Auth ReversalRelease the hold without charging (pre-capture)
Capture ReversalCancel a completed capture (pre-settlement) — see separate section

Implementation notes​

  1. A pre-auth creates an authorisation hold on the cardholder's account. Funds are not captured until you send a Capture.
  2. The hold typically expires after 7–30 days depending on the card network and issuer. Always capture or void before expiry.
  3. Increase / Decrease adjusts the hold with a delta, not a new total, and always references the original pre-auth transactionID. Not available on every acquirer — see the Pre-Authorization Guide.
  4. Always reverse unused pre-authorisations — unreleased holds affect the cardholder's available credit.

Code​

Edge cases​

ScenarioBehaviour
Hold expiryHolds typically expire after 7–30 days (issuer / network dependent) — always capture or void before the expiry window; an expired hold cannot be captured
Capture amount exceeds holdMost acquirers allow slight overages (e.g. hotel incidentals); exceed the allowed threshold and the capture will decline
Unreleased holdFailing to void unused pre-auths affects the cardholder's available balance — always void if you will not capture
Multiple increasesEach Increase adjusts the hold by a delta — confirm acquirer supports multiple increases before implementation

Testing​

ScenarioHow to trigger
Create holdSend with transactionReference — verify finStatus: AUTHORISED and no amount settled yet
Full lifecycleCreate → Capture → query /status/all — verify both operations in chain
Release without captureCreate → Void — verify hold released, no settlement

Key Entry Pre-Auth​

On-device · operator keys card numberCloud APIAndroid (PAX)CordovaJavaScript SDKWindows (.NET)

Places a MOTO pre-authorization hold by commanding a PAX terminal to display a manual card entry screen. Reserves funds without charging — the ISV captures, increases, or voids before settlement.

When to use: For hotel or car rental reservations taken over the phone where the cardholder cannot be present. The operator keys the card number on the PAX terminal's manual entry screen.

Processed as MOTO — acquirer fees apply

Key Entry Pre-Auth is submitted to the acquirer as a MOTO (card-not-present) transaction. MOTO transactions typically carry higher interchange rates. Confirm the fee structure with your acquirer during merchant onboarding.

Implementation notes:

  1. The key entry pre-auth flow supports the full pre-auth lifecycle: Increase / Decrease → Capture → Void.
  2. PAX terminal required — HiLite has no keyed-entry screen and does not support MOTO pre-auth on either path.

Code​

Commands a PAX terminal to display a manual card entry screen. The operator types the card number, expiry, and CVV. Amount in smallest currency unit. Result is async — poll GET /transaction-result/{transactionResultId}.

Pre-Auth Capture​

No card required — settle the held amountAndroid (PAX)CordovaJavaScript SDKWindows (.NET)Backoffice

Captures the funds from a previously created pre-authorization (completion).

When to use: When you know the final amount and are ready to settle. Send the actual charged amount — it may differ from the original pre-auth amount.

Implementation notes:

  1. The capture amount can be less than the pre-auth amount. Most acquirers also allow a small overage (check your acquirer rules).
  2. You must capture before the hold expires (typically 7–30 days).
  3. After capture, a standard refund process applies if the cardholder requests a return.

Code​

Pre-Auth Reversal​

Release the hold without chargingCloud APIAndroid (PAX)CordovaJavaScript SDKWindows (.NET)

Releases a pre-authorization hold without capturing funds.

When to use: When a booking is cancelled or the pre-auth is no longer needed. Always reverse unused pre-auths — unreleased holds affect cardholder available credit.

Timing — not same-day restricted

Reversing a pre-auth hold is not subject to the same-day cut-off that applies to sale reversals. You can reverse the hold at any point before it expires — typically 7–30 days from the original authorization, depending on the card network and issuer. After expiry the hold is released automatically by the network. See Pre-Authorization Hold Durations for card-brand rules.

Pre-Auth Capture Reversal​

Void a captured pre-authorization — releases the chargeCloud APIAndroid (PAX)Backoffice

Pre-Authorization Capture Reversal​

Reverses a completed pre-authorization capture — releasing the funds withheld and returning the transaction to AUTHORISED state.

When to use: When a pre-auth was captured in error and the merchant needs to fully cancel the capture before overnight settlement.

How it differs from Pre-Auth Reversal: Pre-Auth Reversal releases the hold before capture. Capture Reversal cancels the capture after it has been accepted.

Implementation notes:

  1. Must be sent before the batch closes / overnight settlement. After settlement, only a Refund is possible.
  2. Full capture amount only — partial capture reversals are not supported.
  3. Not all acquirers support this operation — check the capabilities table.
  4. Android SDK: The same preAuthorizationReversal() method is used for both voiding the hold (pre-capture) and reversing the capture (post-capture). The gateway determines the correct action based on the state of the original transaction.

Tokenization​

Cygma Token​

EPI · Cygma vault — MOTO detokenization by gateway; ISV stays out of PCI scopeCloud APIAndroid (PAX)Android (HiLite)iOS (HiLite)CordovaBackoffice

What this does​

Reads the card at the terminal and stores it in the Cygma token vault — a PCI-compliant service operated by EPI. The vault stores the PAN and expiry date (no CVV). Handpoint returns a cardToken your system can store for future card-not-present charges.

When to use it​

Use when you want to charge a returning customer without requiring them to present their card again — subscriptions, recurring billing, "save my card" flows. The ISV stores only the opaque token; the PAN never leaves the EPI vault, keeping you out of PCI scope.

How detokenization works​

When you send a MOTO sale with a Cygma cardToken, the Handpoint Gateway retrieves the PAN from the vault internally and forwards the authorisation to EPI — the ISV never sees the raw card number. Your system handles tokens only.

Implementation notes​

  1. Token contents: PAN + expiry date stored; CVV is never stored (PCI requirement).
  2. Token scope: Cygma tokens are specific to the EPI merchant configuration — a token from one merchant cannot be used on another, and test tokens are not valid in production.
  3. Deferred tokenization (recommended): Retrieve a token from a previously completed transaction — no card re-swipe needed. Via Backoffice REST (GET /transactions/{id}/token) — no terminal required, synchronous. Via Android SDK (hapi.deferredTokenization(), SDK 7.1013.1+) — requires PAX device connected.
  4. Future charges: Use the cardToken in Remote Sale (MOTO) — Backoffice POST /moto/sale or Android SDK hapi.motoSale().

Code​

Routes through the connected terminal (requires terminal_type and serial_number). Asynchronous — poll or use callback for the result.

Batch Operations​

Batch Close​

Settle the current open batch with the acquirerBackoffice

Closes the current open batch and triggers settlement with the acquirer. Omit batchNumber to close the currently open batch.

When to use: When you need to settle at a specific time rather than waiting for automatic batch close. Most US host-capture merchants use automatic batch close (~11pm EST) — manual close is only needed for specific settlement timing requirements.

Implementation notes:

  1. US host-capture acquirers only. EU acquirers use automatic settlement and do not require manual batch close.
  2. After batch close, tip adjustments and reversals are no longer possible — only post-settlement refunds.
  3. Auto-close is the default for US host-capture merchants at approximately 11pm EST. Manual close is an alternative, not an addition.
TSYS

TSYS. Batch auto-closes ~11pm EST (host-capture). Partial reversal available for US and Canada — uses the MasterCard flag in ISO 8583. Tip adjustment only available on transactions processed without an on-screen tip (tip-at-table flow).

Parameters​

NameTypeRequiredDescription
serialNumberstringYesTerminal serial number
deviceTypestringYesTerminal model, e.g. "PAXA920"
batchNumberstringNoBatch number to close. If omitted, the gateway resolves the terminal's current open batch

Testing​

Test batch close on the staging device (PAX debug). Batch operations are server-side REST API calls — no card interaction required.

Batch Summary​

Aggregate totals — transaction count and net amounts by typeBackoffice

Retrieves aggregate totals for a batch — transaction count and net amounts by type.

Content-Type: application/json

{
  "serialNumber": "082104578",
  "deviceType": "PAXA920",
  "batchNumber": "132"
}

netAmount is in minor units (e.g. 644397 = $6,443.97). transactionCount includes all transaction types; salesCount and refundsCount are in customFields. closedAt is only present when batchStatus is "CLOSED".

batchNumberstringNoBatch number to query. If omitted, the gateway resolves the terminal's current open batch

Batch Detail​

Individual transactions in a batch, paginated (5 per page)Backoffice

Retrieves individual transactions in a batch for reconciliation. Results are paginated: each call returns at most 5 transactions, in descending order (most recent first). The page size is fixed and cannot be configured.

Pagination:

  1. On the first call, omit retrievalReferenceNumber. The response contains the 5 most recent transactions of the batch, most recent first.
  2. To get the next page (older transactions), send the same request with retrievalReferenceNumber set to the retrievalReferenceNumber of the last (oldest) item in details.
  3. Repeat until details is empty or missing.
Do not stop on a short page

A page can contain fewer than 5 items even when older transactions remain: the gateway leaves out transaction types that it does not report (for example voids). Stop only when details is empty or missing.

let cursor;
const transactions = [];
do {
  const res = await batchDetail({ ...request, retrievalReferenceNumber: cursor });
  const page = [].concat(res.details ?? []);
  transactions.push(...page);
  cursor = page.at(-1)?.retrievalReferenceNumber;
} while (cursor);

Response fields​

FieldDescription
details[].transactionTypeSALE, REFUND, TIP_ADJUSTMENT, PREAUTHORIZATION_INCREASE or PREAUTHORIZATION_CAPTURE. A pre-authorization is reported as SALE — the gateway does not distinguish it in the batch detail.
details[].retrievalReferenceNumberRRN of the transaction. Items are in descending order (most recent first), so the last item of the page is the oldest: use its RRN as the cursor for the next page.
details[].amountIn minor units. For a CLOSED batch it is the settled amount; for an OPEN batch it is the authorized amount. PREAUTHORIZATION_INCREASE always shows the increase amount and PREAUTHORIZATION_CAPTURE always shows the captured amount.

Notes​

  • Open batches: new transactions go to the top of the batch, so they do not appear in the pages that follow. To include them, start again without retrievalReferenceNumber. The cursor is an RRN, not a page number, so you never get duplicates when new transactions arrive.
  • Reconciliation: Batch Detail does not list every transaction type. To check totals, use Batch Summary.

Parameters​

NameTypeRequiredDescription
serialNumberstringYesTerminal serial number
deviceTypestringYesTerminal model, e.g. "PAXA920"
batchNumberstringNoBatch number to query. If omitted, the gateway resolves the terminal's current open batch
retrievalReferenceNumberstringNoPagination cursor: pass the retrievalReferenceNumber of the last (oldest) item in the previous page to get the next page. Omit to get the most recent page
