Test with Adyen
Use the Adyen Payment Simulator to verify that your Bank Transfer via KCP integration works correctly with Adyen. You can test during development, before you go live, and after launch. The simulator does not recreate the shopper's journey through the Bank Transfer via KCP app or website.
This testing option is available by default when you add Bank Transfer via KCP in your test Customer Area. The payment method type is kcp_banktransfer.
To test a redirect payment:
- Start a payment as usual in your integration. The shopper is redirected to an Adyen-hosted simulator page.
- Select the payment outcome that you want to test.
- Wait for the simulator to return the shopper to your website, then complete the payment as usual. For an Advanced flow, make a
/payments/detailsrequest. - Confirm that your integration handles the outcome that you selected, and that the payment appears in your Customer Area > Payments > Payment list.
Test directly with Bank Transfer via KCP
KCP does not provide bank transfer test credentials because the payment must be authorized with a Public Identification Certificate, also known as a Digital Signature for individuals.
