Send Emails via Mailgun’s API directly from the browser

Frontend developers can now directly use Mailgun’s API to send emails from the browser without backend code, utilizing an open standard called Frontend Only Authorization (FoAz). FoAz provides a secure method for API calls by verifying identity, checking permissions, and handling secrets on the frontend, thus bypassing the need for a backend server. This integration allows specific users, such as marketing managers, to send emails by defining permissions with tools like Permit.io, streamlining the process and maintaining access control. In an e-commerce scenario, sales managers can directly send discount coupons via email while maintaining the existing server-side permissions model. FoAz facilitates this by allowing frontend authentication with JSON Web Tokens (JWT) and direct API access, significantly reducing development time and enhancing the efficiency of frontend applications.
