API Versions

API versioning

Offer Searches uses date-based versioning. Every request must send an Api-Version header (for example Api-Version: 2026-02-25) that pins the exact contract your integration was built against, so a newer release never changes behavior underneath you.

The API Versions section lists each published version and its changes. Build against the latest version where possible, and review the changelog before moving to a newer one.

Get started

• Review the request and response schema for your target version under API Versions.

• Make sure you have valid credentials and the correct bearer token scope for your subaccount.

• Send a test search in a lower environment before pointing production traffic at it.
