Obtain an OAuth access token using client credentials.

Exchange your merchant client_id and client_secret for a short-lived Bearer access token. Include the returned token in the Authorization header of every subsequent merchant API call.

Tokens are valid for expires_in seconds (default 3600). Cache and reuse them until near expiry, then request a new one.
