cancel
Use this API to cancel the payment if the payment result is not returned after a long time. The cancellation cannot be performed if being out of the cancellable period specified in the contract. Use the same paymentId or paymentRequestId that is used in the pay API to cancel the payment transaction.
Structure
A message consists of a header and body. The following sections are focused on the body structure. For the header structure, see：
Note: Set the data type of each field (except array) as String. This means that you must use double quotation marks (" ") to enclose the field value. Examples:
- If the data type of a field is Integer and its value is 20, set it as "20".
- If the data type of a field is Boolean and its value is true, set it as "true".

Result process logic
For different request results, different actions are to be performed. See the following list for details:
- If the value of result.resultStatus is
S, the cancellation succeeded. - If the value of result.resultStatus is
F, the cancellation failed. See the returned error code and determine further actions. - If the value of result.resultStatus is
U, the cancellation result is unknown. Use the same request parameters to retry the cancellation request. - If no response is returned, use the same request parameters to retry the cancellation request.
