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.

We have introduced a new parameter, paymentMethodOrder, giving you dynamic, precise control over which payment methods are displayed and the order in which they appear at checkout.

Previously, you could only specify a single preferred method using the paymentMethod parameter. Now, you can:

• Specify multiple methods (Allow-list): Use paymentMethodOrder in conjunction with hideOtherPaymentMethods=true to display only a selected list of payment options (e.g., ['ideal', 'paypal', 'card']). This allows for dynamic, regional payment targeting.
• Custom ordering: Define the exact display order of all eligible payment methods your customers see.
• Flexible preselection: In Inline checkout, the first visible method in your defined order list may be preselected (unless paymentMethod is also used).

This update replaces the need for complex logic to manage multiple payment method visibility, offering a simpler, more robust solution for customizing your checkout flow.

The Stacked checkout display mode has been optimized to better accommodate regional compliance and user experience requirements for our international merchants and buyers.

• Regional compliance updates: Specific verbiage related to tax and regulatory notices for Brazil (IOF message), the European Union (GDPR opt-in), and Japan are now displayed below all payment method accordions.
• Improved layout: This change ensures that essential regional compliance messages do not interfere with the payment method selection flow, providing a cleaner checkout experience in regions requiring additional regulatory information.

We have released a major UI/UX update to the Stacked checkout display mode, focused specifically on improving the subscription management experience for buyers.

• Improved subscription terms display: Subscription terms are now clearly and cleanly displayed above the payment methods section, accessible via a View Details toggle.
• Persistent payment option: The Save Payment Method checkbox is now positioned consistently above the payment options, giving buyers clear control over how their information is handled for future orders.
• Managed subscription clarity: We have removed redundant messages from payment method accordions for managed subscriptions, streamlining the buyer experience.

You can now preview estimated indirect taxes (VAT, GST, sales tax) for products before checkout using the new /products/tax endpoint.

This endpoint enables sellers to display tax for each item before checkout, supporting catalog items and non-catalog (virtual) products. It also supports mixed countries and currencies in a single request to surface accurate, tax-inclusive totals across regions.

Endpoint: POST /products/tax
