New versions of the Transaction API and Payment Form have been posted to the Sandbox and Staging servers. We encourage all 3rd party developers to test their applications against the new releases. The new versions are scheduled to go in to production on June 9th.
The following fields have been added to both the Transaction API and Payment Form:
UMdukpt for pin debit transactions
UMcomments for extended transaction notes
UMsignature for signature capture support
UMresponseHash response variable for transaction response verification
The UMmd5hash and UMmd5key have been superseded by UMhash but will remain supported indefinitely. Applications using UMmd5hash do not need to make any modifications to continue to work with the new release.
The Payment Form now supports custom templates for the transaction response page. To modify the response page template, go to the source key in the merchant console, click the customize payment form button. There are now two tabs. One for the form and one for the response page.
