Improved
Upcoming Breaking Change: Coupon Code Limit
January 30th, 2026
To ensure faster response times and improved stability for our Coupons API, we are optimizing how we handle large datasets.
Effective February 23, 2026, we are introducing a strict limit on the GET /coupons/{coupon_id} endpoint.
What is changing?
The codes array in the response will be capped at a maximum of 1,000 items. This change prevents timeouts and performance degradation when querying coupons with massive code lists.
Action Required:
If your integration relies on this endpoint to retrieve lists larger than 1,000 codes, you should migrate to the List all coupon codes endpoint (GET /coupons/{coupon-id}/codes).
- Current Endpoint:
GET /coupons/{coupon_id}(Limited to 1,000 items after February 23). - Recommended Endpoint:
GET /coupons/{coupon-id}/codes(Supports full pagination).
We recommend updating your integration before February 23 to ensure uninterrupted service.
