[RESOLVED] Return Variable from Paypal (Sandbox) ASP.NET
Hi all,
I would like paypal (after customers subscription) to return some values. Here is my scenario…
- The user visits my subscription web page and fills email (i will use email as username) and password textboxes.
- He clicks on paypal button and he is redirected to paypal page.
- When the transaction is completed he is returning back to my succes registration page.
- When my registration page loads I create the user in my membership database.
This actually means that from the registration page till succes registration page I must carry with me the email and password. In paypal I can define some hiden advanced variables but I cant find any examples of how I can return these values to my site.
- First of all I want to know if my subscription procedure is correct or do I have to do this in some other way..?
- Can paypal return values to my site and how. I am looking for some code example.
Thank you..

Re: Return Variable from Paypal (Sandbox) ASP.NET
All I want to do is to return the email of the user that completes pay transaction… I found this demo over the web but I cant find the link…
don't forget to create paypall sandbox account
So I will need three pages
1. Default.aspx for filling the user email adress and the amount to be send to paypal.
2. Sendpayment.aspx .Sends the data to paypall
3. Paypal .aspx. It is a listener that “listens” paypall transaction status.
