YYYY-MM-DD contract versions. The current version is 2026-08-01, matching info.version in the OpenAPI document.
The date currently identifies the deployed contract and is not a request header. Onlyform does not yet offer per-account version pinning.
Versioning policy
- Additive changes, documentation corrections, and compatible fixes may ship without changing existing request behavior.
- A breaking contract change receives a new date version and a dedicated changelog entry with migration instructions.
- Deprecated behavior is announced before removal when security or legal requirements do not require an immediate change.
- SDK releases use semantic versions and document which API date they target.
