Confirm Payment
A payment can only be captured if it has an Authorized status. The Authorized status can only be obtained for direct credit card, momo wallet payments initiated with Capture parameter set to false.
After successful authorization, the respective transaction will have the status of 9000:Authorized. Partner will process internal operations and call this API to complete the transaction, called confirm API, including 2 statuses:
- Confirm (
capture): Partner processes the transaction successfully, and this status will transfer the money to respective partner’s wallet. Respective transaction from MoMo’s side will complete with Successful status. - Cancel (
cancel): Partner fails to process the transaction, and this status will return the money on hold from the momo to the user’s card. The respective transaction from MoMo’s side will complete with Failed status.
