Postmark has launched a new API that allows developers to fetch and display delivery issues, including bounces, directly in their own dashboard. The API is designed to be easily integrated with Postmark's existing architecture, using server API token authentication for secure access. With the new API, users can now visualize delivery issues in a way that suits their needs, rather than relying on the Postmark UI. The API provides a range of endpoints for working with bounces, including retrieving summaries, fetching filtered lists, and reading individual bounce details. While the developers have done their best to anticipate user needs, they encourage feedback and suggestions from users to ensure the API meets its full potential.
