Objects

Transaction Result

TransactionResult Object

An object holding information about the result of a transaction.

tip

signatureUrl: In case the signature can not be updated to the Handpoint servers and an URL is not generated, the terminal will send back the image binary in base64 format to your software. It is important to be able to support both the URL and the image binary format.

customerReceipt and merchantReceipt: The receipts are usually received as URLs in the transaction result from the terminal. Please note that if the terminal is not able to upload the receipt to the Handpoint cloud servers and an URL is not generated then the HTML formatted receipt will be delivered to your software. It is important to be able to manage both formats.

UNDEFINED AUTHORISED DECLINED PROCESSED FAILED CANCELLED PARTIAL_APPROVAL

Description of the different financial statuses:

Parameter	Notes
`UNDEFINED`	Any Financial Status other than the below mentioned financial statuses will be `UNDEFINED`. UNDEFINED means that the SDK couldn't get a response from the Gateway. An automatic cancellation service will try to cancel the transaction in case it was approved. From Android SDK `7.1.0` we won't cancel transactions anymore and will use `getTxnStatus` to return the actual status of the transaction
`AUTHORISED`	The transaction (Sale, Refund,...) has been authorised. Consider this value as "successful".
`DECLINED`	The transaction has been declined by the acquirer or issuer.
`PROCESSED`	The `printReceipt` operation was successful.
`FAILED`	Status generated due to a network error, a card which can not be read etc. As a general rule, errors are mapped to `FAILED`.
`CANCELLED`	The transaction has been cancelled. For example if the `stopCurrentTransaction` operation has been used or the cancel button on the terminal has been pressed.
`PARTIAL_APPROVAL`	A partial approval is the ability to partially authorize a transaction if the cardholder does not have the funds to cover the entire cost on their card. The merchant can obtain the remainder of the purchase amount in another form of payment. `PARTIAL_APPROVAL` is applicable only to the United States market.

`SdkVersion` String	Gets the current SDK version.
`isTransactionResultPending` boolean	In the case of a communication failure between the payment terminal and the SDK a TransactionResult might have not been delivered. This function checks if there is a pending TransactionResult. This field is only updated when connecting to a payment terminal. If this function returns true the TransactionResult (which includes the receipt) can be fetched.getPendingTransactionResult();. This function serves the same functionality as the event pendingTransactionResult(Device device), so every time this event is invoked, HapiManager.IsTransactionResultPending() is true until the result is fetched.
`Settings.AutomaticReconnection` boolean	When this property is set to true, the SDK will automatically try to reconnect to the payment terminal after a disconnection. The SDK internally maintains a reconnection thread which keeps on trying to connect until it succeeds. The delay between reconnections is exponentially increased on every new attempt. The default value for this property is true

Code example

//Check if the SDK is in transaction
boolean inTransaction = HapiManager.inTransaction(someConnectedDevice);
//Check the current logLevel
LogLevel level = HapiManager.getLogLevel();

//Disable automatic reconnection feature
HapiManager.Settings.AutomaticReconnection = false;

Refund Options

RefundOptions Object

An object to store all the customization options for a refund.

Properties

Parameter	Description
`CustomerReference` String	An arbitrary string to use as your own identifier for a transaction
`MerchantAuth` MerchantAuth	An object containing all the credentials used to optionally authenticate a merchant
`PinBypass` Boolean	Bypasses PIN entry when the shopper says they don't know the PIN for the card and the merchant either knows they are the legitimate cardholder or want to give them the benefit of the doubt. PIN Bypass should be set to True if you want to enable pin bypass for a transaction
`SignatureBypass` Boolean	Whether the terminal prompts for a signature, depends on how you configure this. The major card schemes (American Express, Diners, Discover, JCB, Mastercard, Visa, UnionPay) no longer require a signature; they regard it as optional for card-present transactions. This means you can speed up your checkout by skipping the signature prompt. But if your business requires it, you can still let the terminal prompt for a signature. The shopper then provides their signature on the touch screen of the terminal or on the printed transaction receipt. This depends on how you configure this setting. It is your responsibility to verify the signature of the shopper with the signature on the card or another form of identification. Signature Bypass should be set to True if you want to enable signature for this transaction
`CheckDuplicates` Boolean	Used to disable the duplicate payment check functionality. When a merchant is not 100% sure of the transaction outcome, they will reprocess the transaction leading to the cardholder being charged twice. In order to avoid this scenario, we are flagging the duplicate transaction and prompting a menu to the cardholder/merchant to confirm/cancel the second charge. This menu is pushed by the Handpoint SDK and will automatically be displayed on top of your own UI when required. The Handpoint SDK will only prompt the duplicate payment check menu in case the same card is used twice in a row to process a transaction for the same amount within a 5 minutes timeframe. The duplicate payment check feature is enabled by default but can be disabled by passing a false value.

Code example

RefundOptions options = new RefundOptions();

//If you use a customer reference
options.setCustomerReference("Your customer reference");

//If you need Multi MID / Custom merchant Authentication
MerchantAuth auth = new MerchantAuth();
Credential credential = new Credential();
//Optionally
credential.setAcquirer(YOUR_ACQUIRER);
//Optionally
credential.setMid(mid);
//Optionally
credential.setTid(tid);

//Add as many credentials as acquirers your merchant supports (for example OMNIPAY/AMEX). 
auth.add(credential);
options.setMerchantAuth(auth);

//If you need to enable pin bypass
options.setPinBypass(true);

//If you need to disable the duplicate payment check service
options.setCheckDuplicates(false);

Sale and Tokenize Options

SaleAndTokenizeOptions Object

An object to store all the customization options for a sale and tokenize options.

Parameter	Description
`BudgetNumber` String	The budget number can be used to split payments over a period of months.
`CustomerReference` String	An arbitrary string to use as your own identifier for a transaction
`MerchantAuth` MerchantAuth	An object containing all the credentials used to optionally authenticate a merchant
`PinBypass` Boolean	Bypasses PIN entry when the shopper says they don't know the PIN for the card and the merchant either knows they are the legitimate cardholder or want to give them the benefit of the doubt. PIN Bypass should be set to True if you want to enable pin bypass for a transaction
`SignatureBypass` Boolean	Whether the terminal prompts for a signature, depends on how you configure this. The major card schemes (American Express, Diners, Discover, JCB, Mastercard, Visa, UnionPay) no longer require a signature; they regard it as optional for card-present transactions. This means you can speed up your checkout by skipping the signature prompt. But if your business requires it, you can still let the terminal prompt for a signature. The shopper then provides their signature on the touch screen of the terminal or on the printed transaction receipt. This depends on how you configure this setting. It is your responsibility to verify the signature of the shopper with the signature on the card or another form of identification. Signature Bypass should be set to True if you want to enable signature for this transaction
`TipConfiguration` TipConfiguration	An object containing the tip configuration for this transaction
`CheckDuplicates` Boolean	Used to disable the duplicate payment check functionality. When a merchant is not 100% sure of the transaction outcome, they will reprocess the transaction leading to the cardholder being charged twice. In order to avoid this scenario, we are flagging the duplicate transaction and prompting a menu to the cardholder/merchant to confirm/cancel the second charge. This menu is pushed by the Handpoint SDK and will automatically be displayed on top of your own UI when required. The Handpoint SDK will only prompt the duplicate payment check menu in case the same card is used twice in a row to process a transaction for the same amount within a 5 minutes timeframe. The duplicate payment check feature is enabled by default but can be disabled by passing a false value.

Code example

SaleAndTokenizeOptions options = new SaleAndTokenizeOptions();

//If you use a customer reference
options.setCustomerReference("Your customer reference");

//If you need Multi MID / Custom merchant Authentication
MerchantAuth auth = new MerchantAuth();
Credential credential = new Credential();
//Optionally
credential.setAcquirer(YOUR_ACQUIRER);
//Optionally
credential.setMid(mid);
//Optionally
credential.setTid(tid);
//Add as many credentials as acquirers your merchant supports (for example OMNIPAY/AMEX). 
auth.add(credential);
options.setMerchantAuth(auth);

//If you need to enable pin bypass
options.setPinBypass(true);

//If you need to disable the duplicate payment check service
options.setCheckDuplicates(false);

//If you want to specify the budget period
//Only available for SureSwipe
options.setBudgetNumber(YOUR_BUDGET_NUMBER);

//If you want to specify tip options
//Only available for PAX and Telpo terminals.
TipConfiguration config = new TipConfiguration();
//Optionally
config.setHeaderName(HEADER);
//Optionally
config.setFooter(FOOTER);
//Optionally
config.setEnterAmountEnabled(true);
//Optionally
config.setSkipEnabled(true);
config.setTipPercentages(percentages);
options.setTipConfiguration(config);

//Alternatively, you can set the tip amount directly
options.setTipConfiguration(new TipConfiguration(AMOUNT));

Settings

Settings Object

An Object holding the SDK initialization settings

Properties

Parameter	Description
`automaticReconnection` boolean	When this property is set to true, the SDK will automatically try to reconnect to the terminal after disconnection. The SDK maintains internally a reconnection thread which keeps on trying to connect until it succeeds. The delay between reconnections is exponentially increased on every new attempt. The default value for this property is false
`autoRecoverTransactionResult` boolean	The default value for this property is false
`sendToDeviceMaxAttempts` Integer	Number of retry attemps when there is an error communicating with the card reader. The default value for this property is 3
`timeBetweenAttempts` Integer	Time in milliseconds between attempts. The default value for this property is 5000
`showSDKUIComponents` boolean	The default value for this property is false
`getReceiptsAsURLs` boolean	The default value for this property is false

Signature Request

SignatureRequest Object

A class containing information about a signature verification.

Properties

Parameter	Description
`timeout` int	`int` the value of the timeout in seconds.
`MerchantReceipt` String	`String` the merchant receipt as html. Note that if the terminal is not able to upload the receipt to the Handpoint cloud servers and generate a URL then the HTML formatted receipt will be delivered to your software. It is important to be able to manage both formats.
