An user   9/28/2009 3:06:15 PM Hi. I am not able to get the IPN to work. I have been trying it with the PayPal Sandbox but it isn't working. I did my original testing with a site that was not yet live but it was available as a subdomain of the hosting company. I thought maybe this was the reason it wasn't working so now I've made the site live.   I was able to get the PalPal_Returned event but the IPN_Notified event does not happen.   I changed over to the live PayPal and it works the same.   I am using a buy now button. I have a single page that handles the click event, the return event and the ipn event.  i have checked the Enable PostBack on the BuyNowButton Tasks dialog bux.   My hosting company has set my website to FULL trust.   Any ideas?   I did try to use the SendMail inside my IPN handler to send me some mail messages to let me know if the system ever executed anything inside the handler.    I also did set my return URL and IPN Notification URL inside my PayPal profile to point to the common page (PayPalProcessor.aspx). I assume that your control will override that with it's own address? But maybe that doesn't work?   Thanks, Bob

An user   10/2/2009 10:04:17 AM I tried various permissions but could not run your script file. Then I remembered that I'm using Microsoft's Membership role provider to secure my website. So I moved your script to *****/SpiceLogicTester.aspx and set access to allow all users there. Then when I went there I could see  your script.   I'm wondering if the problem might be that access to my folder is denied for all but logged in users. I may have to create a special rule for the PayPal IPN. Anyway you can try your script from the above address. I didn't run it but could if you want me to. I didn't know what all it does.   Thanks, Bob

An user   10/2/2009 10:08:23 AM Maybe I need to put the following into my web.config <location path="MemberDues/PayPalprocessor.aspx">    <system.web>        <authorization>              <allow users="*"/>        </authorization>     </system.web> </location path>   or create a specific page for the IPN return and set its access in this manner.

Resolution:

An user   10/2/2009 3:22:09 PM OK. I believe my problem is that I DO need to add the following section to my web.config: <location path="MemberDues/PayPalprocessor.aspx">    <system.web>        <authorization>              <allow users="*"/>        </authorization>     </system.web> </location path>   After doing this then the IPN event handler is firing. Now I just need to clean that up and put some additional checks in the code to only let PayPal IPN into that code block. Thanks, Bob
