Response

After the gateway was created successfully, you will get a link in the response of your request. Redirect the shopper to this link for processing the payment.
Also, store the gateway ID in your software, you might need this later.

Payment

Your shopper can choose a payment method in the Gateway and process the payment:

After Payment

The shopper is redirected to the matching URL depending on the outcome of the payment process. (success-/cancel-/failedRedirectUrl)
The decision of whether a transaction was successful should not be made based on the redirect URL used. Always use the Payrexx Webhook or API to determine a transaction status.

Next Steps

Now you have to perform further steps based on the payment result.
