Campaign Monitor API changes

How to track Campaign Monitor API changes

The Campaign Monitor API evolves without warning — endpoints move, parameters change, auth scopes tighten and old fields get deprecated. apik.dev watches the public Campaign Monitor 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 Campaign Monitor changelog by hand, you get a clean, dated record of exactly what changed — and why it matters.
