Upgrading APIs

  • About upgrading APIs — Safely roll out significant changes by running a cloned API in parallel with the original
    • Clone an API — Create an editable copy of a published API without affecting the original
    • Copy API access to other APIs — Transfer an existing API’s subscriber list to the cloned API
    • (Optional) Retiring the older API — If you intend to fully replace the original API with the cloned version, you must retire the original so that traffic routes correctly to the new API
