How to track Mailgun API changes

The Mailgun API evolves without warning — endpoints move, parameters change, auth scopes tighten and old fields get deprecated. apik.dev watches the public Mailgun API documentation for you: we scrape it on a schedule, diff every revision and grade each change as breaking or informational. Instead of re-reading the Mailgun changelog by hand, you get a clean, dated record of exactly what changed — and why it matters.

Subscribe to Mailgun and apik pages you by email or webhook the moment a change is detected — with the full diff, a severity grade and a short migration summary. Filter to Mailgun breaking changes and deprecations only, so you hear about what will actually break your integration and nothing else.
