this is a theorical question dealing with combining ebay api and paypal ipn


selling items on ebay and getting paypal ipn

If I sell to a customer more than once I can not tell which order to add the paypal payment to

I can choose to add paypal payment to ebay order that is the oldest (but that order may be months old)

I can choose to add paypal payment to ebay order that is the newest (but that order may have a customer adding paypal for shipping on an older order)

Got a neglected question alert on this.  Not sure this is 100% on target but I will try to answer with a design pattern that I have used for similar things in the past.

You can generate some kind of unique id, and make it part of the product order identification.  Let's say you sell baseball bats and you have maybe 20 SKUs in your inventory.  In the order for baseball bat numbered  BB-32-19 you might add the unique id so that the product number or name looked something like BB-32-19-X423.  In this scheme, the X423 is a unique key to a row in a data base table.  In the row, you have information about who ordered and what they ordered.

Does that make sense for your needs?

but if another paypal payment ip arrives it doesnt have the 'X423' attached to it

paypal ipn will only have customer name, customer address, customer phone number, customeremail, ebayitem number, ebayusername


so customer could have purchased one bat and then another bat 2 weeks later and system will not know which bat to attach the new paypal payment

or customer could have sent additional paypal to ship first bat
