-Managing OAuth Rate Limits
+Accessing GraphQL Admin API
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+There is a basic GraphQL client which allows you to submit GraphQL queries to the GraphQL Admin API.

+Managing Rate Limits
 ~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 You can optionally pass a ``rate_limiting_management`` object into ``bigcommerce.api.BigcommerceApi`` or ``bigcommerce.connection.OAuthConnection`` for automatic rate limiting management, ex:
