This functionality can only work if you have configured the redirect URL in your account. This can be configured programmatically with the e-nkap Callback URL Setup API. Alternatively, it can be configured directly from your e-nkap Portal account.
When invoking this URL, e-nkap server appends your reference ID that was generated by your server in the initial order placement request and the payment status with the following URL:
<returnUrl>/<your_reference_id>?status=<status>
Where:

  • returnUrl: is the URL configured by you
  • your_reference_id: the unique reference id of this payment that was generated by your server and provided to e-nkap in the initial order placement request.
  • status: the current payment status. See 5.2.2.1

Example

returnUrl: http://api.e-shop.enkap.de/return
Called URL by e-nkap: http://api.e-shop.enkap.de/return/112238uy77889w?status=IN_PROGRESS
