Graceful deprecation

Retiring an API without breaking trust

Every API eventually ages out. How a team deprecates says as much about their program maturity as how they build.

A humane deprecation path

1. Announce — mark the version deprecated in Exchange / the portal with a clear sunset date.
2. Offer the alternative — point consumers to the new version or replacement API.
3. Monitor usage — use API Manager analytics to see who is still calling.
4. Reach out to remaining consumers before the sunset date.
5. Retire — only after usage has drained and consumers have migrated.

What not to do

• Silent removal — the fastest way to break trust across a program.
• A sunset date with no migration path offered.

Coaching note

Deprecation is a relationship exercise. Coach customers to communicate early and often, and to measure before they retire. A well-run sunset builds more credibility with consumers than shipping a new feature.
