Method: referenceNumberPaidNotification

Notify Google that a customer completed payment of a reference number.

It is expected that this will be called within milliseconds of the user paying. While this call can be enqueued if the network is down, Google expects the user will typically receive notification that their payment has been paid by the time they are leaving the store.

If the echo is successful, the endpoint will return an HTTP 200 and the response will be of type EchoResponse.

If the endpoint encounters an error while processing the request, the endpoint will return HTTP 4xx or 5xx and the HTTP body will either be of type ErrorResponse or contain a generic error (e.g. a message similar to "There was an error. Please try again later.").

The generic error is used in situations where an ErrorResponse with a clear description could be used to help an attacker understand the payment integrator account identifier of other integrators. In these situations, where either the signing key doesn't match, the payment integrator identifier was not found, or the encryption key was unknown, this method will return a generic error. If the request signature could be verified, additional information regarding the error will be returned in an ErrorResponse.

An example request looks like:


{
  "requestHeader": {
    "protocolVersion": {
      "major": 2
    },
    "requestId": "cmVxdWVzdDE",
    "requestTimestamp": {

  "paymentTimestamp": {
    "epochMillis": "1481855969203"
  }
}

An example response looks like:
