Working with Paypal

ci_loi

I am having trouble with the return and cancel_return traits.

When the transaction is complete Paypal does not automatically return me to AwareIM.
When a "Return to Merchant" button is clicked from Paypal a broken XML page is shown.

I am wondering how I might control how paypal returns me to the aware server and how to run a process upon a successful return.

ps. I have found the library sample suffers the same problems as my own program so using that as a reference hasn't helped me much.

PayPal never returns to the merchant automatically - you have to press the "Return to Merchant" button. This has nothing to do with Aware IM - this is how PayPal works
What is the exact message that you are getting?

Here is a screenshot of the error.

Is there a typical way that people use to administer users that have paid through paypal but simply closed their window instead of returning to merchant and completing process in awareIM?

christopherb

We use PayPal for a particular application and the instance of a user closing the browser prior to returning has never been and issue.

Just an FYI

Are you sure the same thing happens in the Library application? It is quite a hassle for us to re-test it again and we are quite sure it was tested before and it worked fine. Can you try this in IE (where it was tested, maybe it's the problem with FF?)

ci_loi

Yep. The same problem happens in IE as it does in FF. The only thing I have changed is the URL so that it points to the particular sandbox that I happen to be using.

aware_support

Then it must be the problem with the sandbox. Is there any chance you can try it without the sandbox?

ci_loi

I just tried it with a non-sandbox account and it gave me the same XML error.

RE:ChristopherB

For your application are you using "return" and "cancel_return" as parameters for the URL channel just like the Library example?

aware_support

OK. We'll have to re-test. If the bug is confirmed, we will fix it for the next build.

The pay-pal app we built is a little different from the sample applications.

aware_support

There IS a bug in Aware IM and it will be fixed in the next build.

Also the Library example is missing one important parameter. The PayPalParameters object must have an attribute with the name "rm" and initial value = 2

ci_loi

thank you very much support!

aware_support

This has been fixed in build 1160

Didn't want to start a new post but just thought I'd ask the question of AwareIm support.

Does AwareIM support Paypal's IPN (Instant Payment Notification) or has anyone implemented IPN in AwareIM

Looking at the PayPal stuff is my next task

aware_support

Why do you need IPN? IPN is integration at the code level and obviously Aware IM does not support it (unless you want to write your own plug-ins).

PayPal returns control to Aware IM automatically when the payment is finished or cancelled, so in theory I don't see the need for IPN.

rocketman

Hi support, don't worry about it, I have a blind script written in asp I can use.

FYI - IPN is useful if for any reason the PayPal transaction fails the first time around (Servers busy, problem with credit card, not enough funds etc etc. IPN sends a notification (usually to a "blind" script) which can then mark the members account as "Payment Pending".PayPal then periodically retries the transaction over a period of time until the tranaction succeeds or PayPal gives up.

Either way, a notification is sent to the script which can then flag the members record and react accordingly under (my) process control.

It is used mostly when a site DOESN'T send the customer to the Paypal site to complete the transaction but rather, gathers all the necessary data itself and then sends a complete set of name value pairs to PayPal.

This overcomes the problem of users NOT clicking the return to site button on PayPal which in reality - particularly with single item transactions, like a membership renewal - happens more often than not

If you want to have a play, I can send you the script
