Json Response

The response object is sent to the callback url and contains data relevant to the financial operation. It contains relevant information, extra parameters, a representation of the TransactionResult object returned from our native libraries and any error that occurred.

It is formatted in JSON and structured as a collection of "name":"value" pairs. Values are always a string except in the cases where the value is a boolean or another collection of "name":"value" pairs.

The response will be packed and added to your callbackUrl in the following format https://your_callback_url?data=<packed_response_data> in a GET request.

<packed_response_data> is a JSON string that has been URL encoded to make it safe to use as a GET parameter.
