Loyalty · New: Errors and Testing your integration

October 24th, 2026

Two new pages in General:

  • Errors lists every status code the Loyalty API returns, with real error bodies for v2.0 and v3.0 endpoints. It explains how to back off on 429 using the rate-limit headers, which calls are safe to retry, and what to log for support (X-Request-Id or exception_id).
  • Testing your integration explains how to test without a sandbox. It lists the calls that change points, send emails or create real coupons, and ends with a go-live checklist.

Rate-limit details moved from Guidelines & Conventions to the Errors page.
