The API is versioned by date. The current version is 2026-11-01. Every answer carries it in Delivr-Api-Version, and every webhook in apiVersion and the Delivr-Api-Version header.
What can change without notice
Section titled “What can change without notice”These changes are backwards compatible and ship in the current version:
- New endpoints.
- New optional request fields.
- New response fields, and new fields in webhook
data. - New webhook event types.
- New values in
reason, errorcodeand other open lists. - New options in quotes.
Build your integration to tolerate them: ignore fields and events you do not know, and treat unknown reasons and codes by their category.
What needs a new version
Section titled “What needs a new version”Removing or renaming fields, changing types or meanings, or making optional fields required. Delivr announces such changes to integrators ahead of time.
