![]() You can do query level permissions, object level permissions, and field level permissions.ĭifferent ways to implement permissions in GraphQL In GraphQL, you can go to any depth to implement permissions. ![]() For instance, you can implement permissions through GraphQL directives in the schema or by checking permissions in GraphQL middleware (such as resolvers). You can implement permissions in different ways in a GraphQL API. They are all authorized as users, but based on activity, they have different rights of access. Both the author of the Tweet and other users can participate in the comment thread on the TweetĪs you can see, both the author and other users have different levels of permissions, even though the level of authorization is same.Other users can like, retweet, or share the Tweet.The author who wrote the tweet can delete it.Let’s check some example use cases for permissions.

If the user is logged in but doesn’t have enough permission to perform the operation, the API will throw a forbidden error or an unauthorized error. Usually if a user is not logged in but the API endpoint requires a logged in user, the API throws an authentication error. Basics of access control and permissionsĪccess control – Checking whether the user is authorized to access the API. In this article, we will see different patterns to implement permissions in a GraphQL API. In GraphQL, you can achieve granularity quite easily. Getting granular access control is a big pain in large REST APIs. One such advantage is that it allows you to implement permissions and granular access control in the API. It has its own advantages and flexibility. GraphQL has become the new normal for developing APIs. ![]()
