API functions

Overview

As shown in the workflow there are different API calls during an eps transaction.

  1. check bankstatus
  2. initialise transaction
  3. payment result notification to merchant
  4. buyer redirection to the merchant (triggered by buyer)

check bankstatus

This call should not be used anymore. All eps transactions now use an external bank selection form!

This API call checks, if a bank supports the eps payment method. Therefore the BIC of the buyer's account has to be submitted. The response shows if the bank provides eps. It is recommended to do this prior to an initial payment, to make sure that the buyer's bank supports eps.

Initialize eps payment

The initialisation of an eps can be processed in different ways. This will be distinguished just by the project id.

Torwards a successful initialisation you receive a reference number and an redirect link. The redirect link leads to the online banking account of the buyer's bank. He has to be redirected to his bank. This can be achieved by a HTTP-Redirect-Header, HTML page with an corresponding Meta-Tag or JavaScript redirect.

notification about the payment result

The result of a initialised transaction will be submitted to the prior in the urlNotify parameter specified URL. This notification should be used to update the payment status in the merchant's system.

The result of an eps payment is contained in the field gcResultPayment.

Due to the internal eps process, a redirection of the customer to urlRedirect is not done automatically but only after a customer click.
