    Hi,

    I've implementing automatic paypal processing for a web application. If I use the IPN simulator in paypal sandbox then it works as it should. However, when I try creating a button using the paypal website (using the sellers account) then when I complete a payment the IPN doesnt receive the item_number1 value and I need this to process the payment.

    Anyone ever encounter this before?

    Thanks,
    John

    John_Mc,

    Are you using an "Add to cart" or a "Buy Now" button? Buy Now buttons will not have "item_number1" it will just have "item_number". Can you post the button code so I check it?

    Hi,

    As maceocc2 said previously.. There is no Item_Number1 in the IPN variables list.

    Here's a good list of them:

    I've done a fair bit of work with PayPal and IPN (c# / .net). If you want to post your code up we can have a look..

    Well guys,

    Thanks for your replies. I meant to post up the code last night but didn't get a chance, will do so tonight.

    I tried reading it without the _1 added to the end and it was the same. The paypal IPN simulator does send it with the _1 though.

    Not sure if it's Buy now or a Cart purchase, didnt really know there was a difference to be honest :o

    Will post that code tonight - thanks once again for the replies :)

    Got this to work lads, thanks very much for your replies. I had created a Buy now button so there was no _1 being concatenated onto item_number.

    Was able to confirm this by viewing the IPN history page.

    Thanks :)
