2. Cancellation

Batch and List Cancellation Operations

Batch: You can send a batch payment order, along with its MerchantUniqueCode, to the Paywall APIs to cancel the entire batch payment and all its associated transactions.

List: You can provide Paywall's batch cancellation service with a list of payments identified by your MerchantUniqueCode values (which may be from batch or single transactions). This allows you to complete the cancellation of all listed transactions with a single API call and receive a single callback notification from Paywall in response.
