Get Transaction Details

After the payment is initiated, you can use this API to get the transaction details of an order.

Important:

We strongly recommend that you check the payment transaction status with your payment service provider (PSP). This is to ensure that the transaction is successful before you deliver the goods or services. This also helps you to follow up on the payment status and perform reconciliation if the payment fails.

We also recommend you to check the amount paid in the response received from the PSP and `GetTransactionDetails` API response from Google.

Request

To get the transaction details, make a POST request to the following endpoint:
