Scopes
Scopes are specific permissions for API usage as a given user type. The authorization and token endpoints allow your application to specify the scope of the access request.
Each API endpoint can demand access token with the specific scope. See the endpoint reference for information about required scope.
Please note your application has closed list of allowed scopes, so you should ensure you are able to ask about given scope and always verify the scopes of issued token.
Default scopes are: v2 read write.
