I wasnt to put our order number (internally generated by our ERP system) in Paypal to help track the payments. The only way I see to do this is to use the tracking number field, but when I do that it sends a email to my customer with that tracking number (which is actually the sales order number)
So my questions are:
1. Can I use another field in Paypal to put the sales order number
2. Can I shut off the notification of the tracking number to my customer
