Need help on Custom variable and IPN

[nanko]

Hi,

I have a site which basically allows member to purchase event tickets.  What I would like to do is attach member id number to the paypal transaction.  And then using IPN - I can retrieve the member id who paid us.

Basically I want to activate or members data at my end - and for that I need member id to update database.

The second question I had was is there a way to have IPN enabled with Paypal email link (as opposed to form method)?

I am using email link as my asp.net will not allow html form.  Can someone pl. guide me with above 2?? Also I am willing to use form method but it wont work in asp.net.

Hello nanko, 

Welcome to the Forums.

I would love to try and answer your question, however this question would be more for our Developer Forum. Here is the direct link. I hope this helps.

That's not a problem at all.

You can either enable IPN within your PayPal account's Profile, or you can enter the following in the "Add advanced variables" section of Step 3 of the button creation tool: notify_url=http://link-to-your-IPN-script

Or if you're using non-hosted button, simply append &notify_url=http://xxxxx to the URL.

PayPal IPN will indeed return the value for 'custom' in its POST to you.
