Hello, we have a server-to-server oauth2 application. Endpoint /v2/accounts/{accountId}/plans/usage fails with the message: “Invalid access token, does not contain scopes: [billing:write:master, billing:read:master, billing:master].” 1. Is {accountId} found on the application page under App Credentials? See blow. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/a/e/ae0daded35cd0f40b722388f4c9fe770f6246112.png) 1. Or, is {accountId} an 8 digit number found under the user profile? We only have 1 account so “master” aspect does not apply. Otherwise, account:rw:admin scopes have been given, see below. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/2/4/2495dbe2f189955b9cddf2ada6169f180fb348b7.png) I have read through other similar posts which did not help. Let me know if you need more info. Thank you! Dan ---
