Understanding the Issue: FORBIDDEN Errors with GitHub GraphQL API

If you've ever encountered a FORBIDDEN error while trying to access your private repositories through the GitHub GraphQL API, you're not alone. This common problem often arises when developers misuse access tokens obtained through improper configurations. In this guide, we will explore a specific scenario involving the GitHubAuthProvider used alongside Firebase authentication and the steps needed to resolve the issue effectively.

The Problem Scenario

In the scenario at hand, an individual was using GithubAuthProvider with the repo scope to gain access to user tokens intended for querying the GitHub GraphQL API. However, several queries returned empty arrays or errors related to access permissions. The following sample query succinctly illustrates the attempt to fetch repository details:

But the response was less than satisfactory:

Clearly, there's a disconnect between the permissions granted and the expectations of the API response.

Breaking Down the Solution

Step 1: Understanding GitHub Apps vs OAuth Apps

The first thing to understand is the essential difference between a GitHub App and an OAuth App:

GitHub Apps are designed for integrating with GitHub services and act on behalf of users without needing their login credentials. They have granular permissions and can access resources such as repositories and organization data.

OAuth Apps, on the other hand, allow users to grant permissions for a specific set of actions to third-party applications (like Firebase). They require explicit user authorization and can provide broader access, especially to OAuth scopes like repo.

Step 2: The Misconfiguration

In the original setup described, the developer mistakenly created a GitHub App instead of an OAuth App. This misconfiguration was the root cause of the FORBIDDEN errors, as the GitHub App permissions did not align correctly with the data being queried.

Step 3: Switch to OAuth App

To remedy the situation, it’s crucial to create an OAuth App in your GitHub account settings instead of a GitHub App. Here's how to do it:

Go to your GitHub Account settings.

Navigate to Developer settings.

Click on OAuth Apps.

Click on New OAuth App.

Fill out the necessary fields, ensuring you enable the appropriate repo scopes under permissions.

Once created, use the new client ID and secret to authenticate users via Firebase.

Step 4: Test Your Queries Again

After configuring your OAuth App, try running the GraphQL queries again. You should experience normal access to your private repositories, and the error that initially blocked your progress should no longer occur.

Conclusion

By understanding the distinctions between GitHub Apps and OAuth Apps, we can avoid configuration errors that lead to FORBIDDEN issues when accessing the GitHub GraphQL API. If you are facing similar issues when integrating with Firebase authentication, make sure to evaluate your app type and permissions carefully. With the right setup, your queries should execute smoothly, ultimately providing the intended results without access errors.

Now, go ahead and implement these changes to streamline your access to the GitHub API seamlessly!
