multi-line custom data

[physh]

We have a site that offers Paypal as a payment option.

Our form posts data to https://www.paypal.com/cgi-bin/webscr and includes hidden fields item_name (a generic "oursite cart contents") and item_number (a unique id per transaction).

Is it possible to send to Paypal a complete list of items purchased, instead of just "oursite cart contents"? There may be 20+ different items included.

If this is possible, would the details always be sent to the customer in their receipt email, or can this info be only available to the site owner when they log into Paypal?

thanks

I found the solution - use the cart upload command, ie change form variable cmd from "_xclick" to "_cart"
