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

Responses to this query may be empty if this method does not return an HTTP 200. The response body is empty 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 an HTTP 404 with an empty body. If the request signature could be verified, additional information regarding the error will be returned in the response body.

An example request looks like:

  "requestHeader": {
    "protocolVersion": {
      "major": 1,
