A Multiplayer API error, sent with HTTP 403. Status: the Multiplayer API is in private alpha; this code is part of its published contract.
When
The player token does not grant what this route needs (its can list).
What to do
Mint the token with the capability the route needs, or call the route from your backend with the secret key.
The answer
Every error is a JSON body with a stable error code. Clients act on the codes they know and treat any other code as a failure of its HTTP status, and keep fields they do not know.
