Method: generateReferenceNumber

Stay organized with collections Save and categorize content based on your preferences.

Creates a reference number and registers payment information (description, timestamp) with the integrator.

The combination of the paymentIntegratorAccountId from the request and the referenceNumber from the response form a unique key that identifies the transaction for subsequent operations on this transaction.

The amount field is defined in micro currency units (micros), which means that $2 would be represented with the digit 2 followed by six digits 0, resulting in 2000000.

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": 0,
      "revision": 0

  "transactionDescription": "Google - Music",
  "userInfo": {
    "noUserInfo": {}
  },
  "currencyCode": "USD",
  "amount": "2000000"
