Why does my GitHub API request return a 403 error?

GitHub requires a mandatory 'User-Agent' header for all API requests. Without this header, the GitHub API will reject the connection with a 403 Forbidden status.

What scope is required for Microsoft Graph user info?

You must include the 'User.Read' scope in your authorization request to access the Microsoft Graph '/me' endpoint for profile data.

Why can't I use MSAL.js in Cloudflare Workers?

MSAL.js relies on browser-specific APIs like localStorage and DOM, or Node.js crypto modules, which are unavailable in the V8 isolate-based Workers runtime.

How do I handle private GitHub emails?

If a user's email is private, the standard user endpoint returns null. You must request the 'user:email' scope and fetch the email list from the '/user/emails' endpoint.

API Development

Implements secure OAuth 2.0 flows for GitHub and Microsoft Entra in Cloudflare Workers and other edge environments.

This skill provides specialized guidance for implementing authentication in edge runtimes where traditional libraries like MSAL.js fail due to the lack of browser or Node.js-specific APIs. It streamlines the implementation of GitHub and Microsoft Entra (Azure AD) integrations by providing boilerplate for manual token exchange, provider-specific header requirements, and JWT validation. It is an essential resource for developers building serverless applications on Cloudflare Workers who need to handle complex authentication flows, private email retrieval, and tenant-specific configurations without the overhead of heavy client-side dependencies.
