This section will explain how merchant can initiate GoPay Tokenization (Pre-Auth) transactions using SNAP-based CoreAPI specification.

1. In order to do GoPay Tokenization transaction, merchant should link the customer's GoPay account first by initiating the Account Linking API.
2. Once linked, merchant can reserve user's balance by initiating auth payment (auth API)
3. To actually deduct user's balance merchant will need to capture the authorized transaction (capture API)
4. If merchant wants to release user's balance without actually deduct the balance, merchant will need to void the transaction by calling Void API. Authorized transaction that is not captured after its expiry time will be auto canceled.
5. Merchant can also do other subsequent actions such as Refund, and Get Status.

📘

Currently GoPay Tokenization pre-auth only supports No PIN transaction. Please contact your Midtrans sales representative to enable pre-auth transaction.

📘

GoPay Tokenization in BI-SNAP flow can also support both GoPay & GoPay Later payment. Merchant should pass the corresponding payment option token as payOptionDetails.additionalInfo.paymentoptiontoken in the request body. The payment option token can be retrieved from Binding Inquiry API.
