I am having problem with my IPN script regarding the paypal transaction number. I am using paypal cart, I guess paypal forwarding paypal cart transaction number to my script while the customer receive paypal transaction number. I am having problem with this in my script because they two numbers are different and for my customer to get the item he/she purchased she/he must enter the paypal transaction id the problem is that the transaction ID recorded by my ipn script is not much to the number entered by my customer. I have check this in my paypal account and noticed that the cart number and Paypal transaction number is different. How can I get both number recorded by my IPN script , which variable holds the paypal transaction number and what is the variable for the paypal cart transaction number. I will appreciate any lights
Try looking at this page, it lists all the variables that Paypal passes back to your site during the IPN process: https://www.paypal.com/IntegrationCenter/ic_ipn-pdt-variable-reference.html From what you are describing, I would guess you want one of these variables: Without seeing your code I'm betting that you want the txn_id but your script is currently grabbing the auth_id.
