Samples and guides for integrating apps with External ID
Microsoft maintains code samples that demonstrate how to integrate various application types with Microsoft Entra External ID. We provide instructions for downloading and using samples or building your own app based on common authentication and authorization scenarios, development languages, and platforms. Included are instructions for building the project (if applicable) and running the sample application. Within the sample code, comments help you understand how these libraries are used in the application to perform authentication and authorization in an external tenant.
