Webshop order- and invoicenumber leading

In order to avoid confusion in communications between all parties (PSP, AfterPay and merchant) and to be able to quickly find orders and invoices, it is important that all parties use the same order- and invoicenumbers.

Therefore, the order- and invoicenumber of the webshop should be leading in all transactions passing through your platform to AfterPay.

PSP reference
If you need to use a unique identifier/reference generated by your platform, do not change or use the order- or invoice fields. Instead, you can use the PTR (Parent Transaction Reference) or TR(Transaction Reference) fields.

Please see the overview of authorization and order maintenance objects in the API documentation for more info on these fields.
