- Merchant-applied coupons (Coupon passed during subscription creation in the API)
- Customer-applied coupons (Coupon entered on the hosted checkout)
Coupon Flow
Method 1: Merchant-applied Coupon
The merchant can apply a coupon while creating the subscription by passing the coupon details in the coupon object. The coupon is automatically applied when the customer lands on the Transact Bridge hosted checkout page. The customer does not need to enter the coupon code manually. For step by step integration with method 1 refer to API guide.Method 2: Customer-applied Coupon
The coupon system allows partners the flexibility to use their own coupon store while enabling customers to enter coupon codes directly on the Transact Bridge hosted checkout page. When a customer enters a coupon code, Transact Bridge calls the Coupon Verify API configured by the merchant. The merchant validates the coupon in their own system and returns the appropriate response.For step by step integration with method 2 refer to checkout guide.

- Coupon creation, validation, expiry, and business rules are completely managed by the merchant.
- The Coupon Verify API is invoked only when the customer manually enters a coupon code on the hosted checkout.
- Merchants can support fixed amount discounts, percentage-based discounts, and limited-period promotional offers using their own coupon management system.
