How to monitor API changelogs and deprecations before they break production
The question
Every integration you depend on can change under you — endpoints deprecated, auth schemes sunset, rate limits tightened. Most teams find out from a failing job. Here is the watch method that finds out from the changelog instead.
The method
- Inventory what you actually depend on. List every external API, SDK and webhook in production — including the ones inside third-party plugins. The outage that hurts is usually the dependency nobody listed.
- Find each vendor's real change surface. It's rarely just "the changelog": check the API changelog, the deprecation/sunset page, the status page, and the developer blog. Some vendors announce breaking changes only in one of the four.
- Watch pages, not promises. Email announcement lists are best-effort; the published page is the record. A watcher that diffs the page catches what the email skipped.
- Separate "changed" from "breaks us". The triage question for every entry: does this touch an endpoint, field, or auth flow we call? Everything else is noise. This filter is the entire value of monitoring — unfiltered changelog feeds get muted within a month.
- Track deadlines like an ops calendar. Deprecations come with sunset dates. The day to migrate is not the sunset day — put the date in the calendar the moment it's announced, with an owner.
- Verify against the source before acting. Before rewriting an integration off a summary (including ours), read the vendor's actual page. Honest tooling links you there; that's the standard to hold any tool to.
The honest shortcut
VendorWatch runs this method as a product: declare your stack, and it watches your vendors' published change surfaces, filters for what touches you, and cites the vendor's own page on every alert — nothing paraphrased without a link. The free audit shows you what it finds for your stack today, no account.
