See the API calls behind cashback in your product. Run the sandbox example below, then explore shopping requests against real stores. Every request and response is available to inspect.
We spent years plugging into the backend of thousands of online stores so that you don’t have to.
Sandbox · no real money
Try the cashback API
Quote cashback, report a purchase, connect a receiving account and send the reward to your wallet. See the actual requests and responses as each call runs.
This example skips the 30-day hold and simulates the bank: the verification deposit, the transfer, receipt and user credit. It places no order and moves no real money.
Subtotal after discounts, excluding tax, shipping and gift cards. Each run uses a fresh sandbox user.
