To use the PSP Nexi via COPAL, the following credentials are required:
- Checkout Key
- Secret Key
- WebhookSecret
- TermsUrl
The secrets are provided by Nexi and can be retrieved from the Nexi backend. Please follow these steps:
- Log in to your backend account.
- Click on Company in the menu bar, then select Integration.
- The data is available for both the live and test environment.
- If the Merchant ID is also required, you can find it under Integration as well (see screenshot point 5)
The TermsUrl is the web address (URL) where the payment terms of the online store can be found.
The WebhookSecret is a freely definable value consisting of numbers and letters, which must contain at least 20 characters. This value is sent with the payment request and validated when collana pay receives a notification from the PSP.
