question

Hi @mustafazalsoufi,

The URL you provided is a Client API Endpoint which requires a client session ticket for authentication, available from any Client Login function such as LoginWithCustomID. The ticket is passed in the header when you are trying to make an Http request to that endpoint. The GetUserData API that takes a secret key for authentication is the Admin API: https://cab1e.playfabapi.com/Admin/GetUserData, which is almost the same as the Client API except that it requires a secret key in the header for authentication. Therefore, the URL needs no more combination, you’ll need to pass the secret key in the header in order to make a successful request.

By the way, PlayFab JavaScript SDK provides everything you need to access the PlayFab API. This includes models, methods, an HTTP wrapper for sending and receiving web requests, and JSON serialization. In your case, if you want to make an Admin API call such as Admin/GetUserData, this code will simply set the secret key in the PlayFab settings and include it in the header when making subsequent calls. And, it's also helpful to use PlayFab Postman collection to debug and test APIs.
