We need a script to be used at the 'return' URL to receive and validate
the IPN from Paypal and then display the following fields:
txn_id, first_name, last_name, payer_email, item_name, item_number,
amount, invnum and custom.
This is a very simple script but only respond if you have done Paypal
PHP IPN integration before.
I'm ready for this project. Have completed similar projects many times. One thing, the IPN script can only receive data and then save/update related records. It can not be used to display something to the end user.
