Making API Requests with User Token

• Using the key that is returned in the authentication response. Generate a new HMAC [signature] where the key returned in the response replaces the previously used PrivateKey.
• Add an additional header value of x-ct-user-token to the HTTP Header and place the token that is returned in the authentication response into the header.
• The user_id will need to be included in the request URL to identify the end-user when requesting the user-data related APIs.

The below examples show how the header and endpoint values will appear with a token and updated [signature] in the header.

Example Headers for an API request retrieving a user’s activity with user_id=123456789:
