API versioning and deprecation
Track API versions in use, traffic still on deprecated versions and breaking changes.
Delivery & developer experienceHow it's worked out
- Shares are of traffic, breaking changes or endpoints
- Version from request headers or path; consumers by API key
NoteEach supported version costs testing and security effort. Contact the largest consumers on deprecated versions directly.
