How do I change obsolete Paypal IPN URL? - paypal

Paypal wrote, "Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:" But the URL was an old cart address discontinued and replaced a year ago. How do I switch them to the new address?

Depends on where it was set. Check your PayPal profile under Instant Payment Notification Preferences. If that's not where it's set then it must be in the NotifyURL parameter of your shopping cart's API requests.

How to get IPN notification for subscription at client site if user suspend it from paypal account interface

I want to update the status of subscription in database based on changes in PayPal user's account. I am not getting any notification from paypal side for it. What should I do for it. Our site is working as a platform and our client provide subscription for their customers. So when a customer changes the status of subscription in PayPal side then the same status needs to update at our side. We have used IPN not API. Please suggest.
It depends on the type of the subscription integration you have.
If it is a classic subscription that was created with a notify_url specified for IPN, then you should receive an IPN message with the txn_type subscr_cancel, as documented here: https://developer.paypal.com/docs/api-basics/notifications/ipn/IPNandPDTVariables/
If you have a current PayPal Subscriptions integration, you can subscribe to the webhooks event BILLING.SUBSCRIPTION.CANCELLED, as documented here: https://developer.paypal.com/docs/api-basics/notifications/webhooks/event-names/#subscriptions

After modifying the PayPal IPN URL, still using old IPN listener URL for some notifications

I'm working on a project which has PayPal integration. We have two PayPal accounts for payment and choose the PayPal account based on the type of users. We previously had two IPN listeners for the two different PayPal accounts. Previously our IPN was pointed to "https://www.old-domain1.com/paypal/ipnhandler" and "https://www.old-domain2.com/paypal/ipnhandler". Yesterday we have updated two websites into one and we started to use a common IPN to this address "https://www.new-domain.com/paypalipn/paypal/IpnHandler" to the new project.
We have added the common IPN URL on both PayPal accounts. But we could see PayPal is still sending the IPN to the old IPN handler for the old recurring payment. Our old IPN handler URLs are not currently working and we don't have the option to update the payment if PayPal is still sending the notification to the old URL. For some users, it worked correctly. For some users PayPal still using the old IPN URL. Why does this happen?
Now we have one IPN listener for two different PayPal accounts. Is this related to the problem?
If a URL was specified as part of setting up the transaction (i.e. by the software/site when the user was redirected to PayPal), that transaction-level specification supersedes any setting in the PayPal account. It is now set in stone for anything related to that transaction/recurring profile, and cannot be changed.

issues with notify_url in paypal

I am a developer and we have paypal payment sytem integrated with our shop since long.
We have implemented the notify_url paramter in checkout code and was working fine since 4 months back. But now we could see that when a payment is done, we are not notified via the notify_url we specified. But however if we check the url via the IPN simulator, we can see everythign works as expected, but not not notifying automatically when payment is done .
What could be the issue or what all do we need to cross check for this issue to be solved
Did you received any 'PayPal Instant Payment Notification Warning' email from PayPal? This email could be telling you that there's an issue with your IPN URL when PayPal trying to post back the notification to your server, and that could be the reason you didn't receive the notification message from PayPal.
Otherwise, I would recommend you to contact PayPal technical support via https://www.paypal-techsupport.com/app/ask and providing the detail of your PayPal account for them to troubleshoot on this issue.

How to check Payment failure for Paypal Express Checkout

We are using Paypal recurring billing service (using Express Checkout) at our website for monthly subscription.
Since we have an Australian account so we are not able use the DPRP (Direct Payment Recurring Payment) service offered by Paypal because it seems, DPRP service is limited
to only few countries (US, UK and Canada).
In Express checkout payment details are received at Paypal Website. So we do not have any information, whether the payment failed, user pressed the Back button in browser or He/She intentionally clicked the cancel payment.
After speaking to Paypal support team we get know that there could be multiple possible reason for Payment failure, and seller has to contact Paypal by themself. So we can
not provide any troubleshooting for that at our website.
So we want to know, Is there any possible solution to avoid this or atleast can we diffrentiate between the user for whom payment failed and who intentionally moved to
our website back without doing payment because this way we are not only unable to followup with them but also loosing a part of the customer base, interested in our service.
Any help in this is Appreciated.
Thanks
You should implement the Pay Pal IPN (Instant Payment Notification).
You configure the IPN url address on your PayPal merchant account settings. This page is simple HTML page with server-side programming that is listening for requests coming from PayPal.
There's no need to do something extra in the checkout process for making IPN work. Once you set this up, it will automatically work.
Every time something happens with a transaction in your merchant account, e.g. transaction completed/failed/canceled, PayPal will send an HTTP Post to your IPN listener URL.
Here you can get all the relevant information about the transaction, like the payer ID, the payment status. With this information you can decide what to do with your customer's order.

DNN and PayPal, how to sent email to customer after payment has been made

In my DNN website, using Paypal's Checkout button, when user has click the buy button and sent to Paypal. Make a payment and then redirect back to my site.
Question:
How can I get that customer email address (from Paypal) so that i can sent a conformation email to him/her from my DNN website?
thanks.
Two ways; you can either call the GetTransactionDetails API and supply the TRANSACTIONID as a parameter. 'EMAIL' will contain the buyer's (PayPal) email address.
Or you can use PayPal IPN to get notified through POST whenever a payment / action has been made.
GetTransactionDetails API doc is at https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_api_nvp_r_GetTransactionDetails
You can also have a look at TransactionSearch for past transactions.
In case you want to use IPN, just supply NOTIFYURL in your SetExpressCheckout and DoExpressCheckoutPayment call if you're using Express Checkout, or if you're using Website Payments Standard.
Remember to send the POST back to PayPal for validation at paypal.com/cgi-bin/webscr?cmd=_notify-validate and check for a VERIFIED / INVALID response.
Some sample code and docs for IPN is available at https://www.paypal.com/ipn/
