Cancel payment by idempotency key
Cancels (voids) a payment identified by the idempotency key that is specified in the request.
Use this method when the status of a
CreatePayment request is unknown (for example, after you send a
CreatePayment request, a network error occurs and you do not get a response). In this case, you can
direct Square to cancel the payment using this endpoint. In the request, you provide the same
idempotency key that you provided in your
CreatePayment request that you want to cancel. After
canceling the payment, you can submit your
CreatePayment request again.
Note that if no payment with the specified idempotency key is found, no action is taken and the endpoint returns successfully.
