merchantOrderReference property
You can use this reference to link multiple transactions to one another (for example, to track order authorization rate). For each billing cycle, this reference should be unique. After the first authorized payment attempt, do not reuse the reference. If you use this parameter, include it in all of the payment requests that you make. We strongly recommend that you: * Always include this parameter, so that you can benefit from linking payment requests to one another, in case of authorization retries. * Additionally include the following parameters in the additionalData object: retry.orderAttemptNumber, retry.chainAttemptNumber, and retry.skipRetry
