There are two key points to look at when it comes to oauth2 accounts. I’m not sure what api you are using, but more likely than not its documentation talks about “sending token as Authorization header”. If that’s in the API spec, that means you need to check the “Header Authenticated” option in the account, that indicates that the access token (typically a bearer token) will be sent as an Authorization header to the end point in the format Bearer <access_token>
. Different apis respond differently to missing that authorization, some will respond with a 401, it seems the one you’re using responds with a 499.
