Header Parameters
Pin the API version an integration was built against (date-based, e.g. 2026-07-01). Omit to use the current version. Public URL paths stay stable and unversioned; breaking changes ship under a new dated version and are announced with Deprecation and Sunset response headers. The served version is echoed in every response's Unifapi-Version header. Policy: https://unifapi.com/versioning.md
"2026-07-01"Value in
- "2026-07-01"
Client-supplied unique key that makes a write request safe to retry. If a request with the same key was already processed, the original response is replayed (with Idempotency-Replayed: true) instead of executing — and billing — again. Send a fresh UUID per logical operation. Best-effort with a 24h window.
