PG has prepared plenty of merchant tools for merchants to initiate status requery and cancellation/void of transaction. However, merchants are not allowed to send in requests too frequently (maximum 1 query every 5 seconds). Massive incoming query will lead to IP blocking without prior notice. There will be a validity duration to initiate a status requery API call, generally within 1 hour after the initiated time for online payment and the due time for offline payment.

The back-end services available are:

Direct Status Requery - merchant send status query to processing bank directly
Indirect Status Requery - merchant send status query to PG system
Daily Transaction Report (Reconciliation) - list all transactions of a specific date
Settlement Report (Reconciliation) - settlement details
Capture Request - to capture any pre-auth or authorized transaction
Reversal Request - merchant to cancel or void a transaction or refund of payment
Partial Refund - for merchant who requires partial refund only
Partial Refund Status Inquiry by Txn ID
Channel Status API
Card BIN information API
Foreign Exchange Rate API
Void Pending-Cash API
Recurring Plans API
Payment Token API
