Coupons in Clink allow you to offer discounts to your customers. These can be applied to individual bills, specific subscriptions, or an entire customer account.
Key Concept: It is helpful to understand the two-layer structure:
  • The Coupon (The Rule): Defines what the discount is (e.g., “$2.50 off”) and its validity.
  • The Promotion Code (The Key): The specific string (e.g., SUMMER2025) a customer enters. A single Coupon can have multiple Promotion Codes.
