American Express Pay with Points
American Express Pay with Points allows cardholders to use the points they have earned through their American Express Membership Rewards program to make purchases at participating merchants. This Global Pay with Points API provides flexibility and convenience to cardholders, letting them apply points toward a variety of expenses such as travel, shopping, dining, and more directly at checkout, and gives merchants and partners a programmatic way to offer real-time points redemption within their own commerce flows.
