Method: gsp.facilitated-transaction-event-v2.eventNotification

Notify Google that an event has happened on a transaction. There are nine event types. See examples below

Calling this method has no financial impact on the transaction. It informs Google's risk engine that this transaction was authorized to make more informed choices in the future about this account and instrument.

Responses to this method will return SUCCESS when the request properly sent to Google's risk engine.

An example event request for a refund looks like:


{
  "requestHeader": {
    "protocolVersion": {
      "major": 2
    },
    "requestId": "ZWNobyB0cmFuc2FjdGlvbg",
    "merchantId": "merchant:1234567890",
    "requestTimestamp": "1481899949606"
  },

        "rawCode": "48"
      }
    }
  },
  "eventTimestamp": "1481899949394"
}

An example event success response looks like:


{
  "responseHeader": {
    "responseTimestamp": "1481900013178"
  },
  "result": "SUCCESS"
}

An example event failure response for an invalid transactionId looks like:


{
  "responseHeader": {
    "responseTimestamp": "1481900013178"
  },
  "errorResponseCode": "INVALID_IDENTIFIER",
