Paypal IPN and btn_id -

-

i looking @ php script, , noticed method handles paypal's ipn calls expects receive value btn_id.

but there no such value @ all. has paypal replaced else? maybe txn_id?

the script expects receive value of subscr_id, , paypal send it.

depending on type of ipn gets sent there different possible parameters on ipn, depending on script you're looking @ , it's doing may or may not handling things correctly.
