API deprecation policy

Last updated: 21 August 2026

Audact gives customers a minimum of 12 months’ notice before removing or breaking an endpoint. This applies to public REST endpoints, webhook payloads, and stable SDK surface area.

1. Notice channels

  • Deprecation announcement in the public changelog
  • HTTP `Deprecation` (RFC 9745) and `Sunset` (RFC 8594) response headers
  • Email notification to the customer admin contact and registered technical contact
  • Banner in the platform dashboard

2. Dual-running window

Old and new endpoints run in parallel for the full 12-month window, with migration documentation published the same day the deprecation notice is issued. Compatibility shims may extend the window for breaking changes with regulatory implications.

3. Security exceptions

Where an endpoint must be removed faster due to a security or compliance defect, Audact will give the shortest reasonable notice (target ≥ 30 days), publish a CVE-style advisory, and assist affected customers with migration at no additional cost.
