Overview

Applies a coupon code to a payment status, reducing the amount due. The payment status must reference a coupon-eligible entity type: Meeting, EventAttendance, PendingBooking, or Cart. Payment statuses for other entity types (e.g., Invoice, ClientBookingPackage, ProductOrder) will return 422 "Invalid Coupon" even if the coupon code itself is valid.

Available for Staff, App, and Directory tokens.
