iOS SDK - Response Handling

Errors Passed to the SDK

Effective as of iOS SDK 5.4, the WLW platform passes failure response data in the PDPaydiantError class, which identifies the unchanged HTTP code, along with a context-specific description and an instance of PDErrorInformation object, encapsulating the raw failure response body. The errorCode and errorDescription represent the event status, plus an external error code passed by a third-party entity through the connector framework, if applicable.

The following XML sample depicts the general structure of the server error object.

<?xml version="1.0" encoding="UTF-8"?>
<PDPaydiantError>

ErrorInformation Values

The PDErrorInformation is populated with the errorCode and errorDescription values defined in WLW’s platform. The following tables define each possible value within the code ranges that have been designated for specific operation types.

Note: Not all codes within each designated range have assigned definitions.

Payment Status Code Reference

Payment status codes are not error codes in that they are not returned to the app in failure responses. Rather, they represent the outcome of a payment authorization request as it is returned to WLW by the processor and are returned to the app within the PaymentStatusCode attribute of a PDTransactionAccount instance returned in a success response at completion of a payment transaction. In transactions where one or more payment attempts failed before the transaction was ultimately successful, the previousPaymentResults attribute of the PDTransactionDetail object may include PDTransactionAccount instances populated with values from this list.
