| 15 | |(% style="text-align:right" %){{code}}payment{{/code}}|The URL of the affected Payment. Perform a GET request on it to retrieve the Payment status. | ||
| 16 | |(% style="text-align:right" %){{code}}paymentNumber{{/code}}|The human identifiable number of the Payment, used when talking or writing about the Payment. Only the URL should be used to programmatically identify the Payment. | ||
