When implementing Customer Identity via server-side REST API in SAP Customer Data Cloud, you must add the IP address of the backend to the IP-Allowlist in the Console to start making API callsagainst your existing API key. This ensures that only requests from allowed IP addresses can interact with the SAP Customer Data Cloud, enhancing security.
* IP-Allowlist Configuration:
* Navigate to the site settings in the Console.
* Add the IP addresses of your backend servers to the IP-Allowlist.
* Security: This step ensures that only specified IP addresses can make API calls using your API key, preventing unauthorized access.
