Method: asynchronousCapture

Triggers the start of a money movement operation between a customer's account and the integrator. The integrator should acknowledge the request and perform whatever actions need to happen in order to complete the capture (e.g., collect a PIN from the user). The integrator will inform Google of the capture's final result by calling the CaptureResultNotification API.

The combination of requestId within the header and paymentIntegratorAccountId is the idempotency key and uniquely identifies this transaction. All mutations on this transaction (refunds) populate the requestId value in the captureRequestId field.

If the endpoint encounters an error while processing the request, the response body from this endpoint should be of type ErrorResponse.

An example request looks like:


{
  "requestHeader": {
    "protocolVersion": {
      "major": 1,
      "minor": 1,
      "revision": 0
    },
    "requestId": "bWVyY2hhbnQgdHJhbnNhY3Rpb24gaWQ",
    "requestTimestamp": "1502220196077"
  },
  "paymentIntegratorAccountId": "InvisiCashIN_INR",
  "upiDetails": {
      "vpa": "foo@icici"
  },
  "transactionDescription": "Google - Music",
  "currencyCode": "INR",
  "amount": "728000000"
}

An example response looks like:


{
  "responseHeader": {
    "responseTimestamp": "1481900013178"
  },
  "result": "ACKNOWLEDGED",
  "paymentIntegratorTransactionId": "aW50ZWdyYXRvciB0cmFuc2FjdGlvbiBpZA"
}
