I'm using sandbox accounts to test SetExpressCheckout and DoExpressCheckout methods. However, I'm not receiving any IPN notifications.
My PC has public IP and firewall is off, so I'm expecting IPN posts but none are coming. Is there anything I should do (e.g. any profile settings) to start receiving IPN? (I'm using the Java SDK and passing the notify_url as parameter)
I'm also checking the "IPN History Page" from PayPal.com and I do not find any data there. Am I supposed to find IPN data in this page even if I use the sandbox accounts?
Thanks for your help
EDIT: I solved the problem by transfering my code to another server. something must have been wrong with my public IP.
Make sure you have IPN enabled in your test Sandbox PayPal account. Also, you will not see IPN messages in your PayPal account if you are going to www.paypal.com. This would only be for live IPN messages sent through your live account. If you are wanting to see the IPN messages for your sandbox transactions, you would need to log into the sandbox seller account and view the IPN messages from there.

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.
I have a question about Paypal IPN, I was wondering when does the IPN activate and send it's message to my website.
I currently have my website that has a buy button. When the client buy the service, he is directed to paypal. Once he pay the service, nothing happen. In order for me to receive the IPN notification, the user has to click "Return to merchant website" or whatever the link is, then I receive the IPN notification.
Is it normal, does it work like that for everyone?
Cause right now, most people when they are done with the payment, just close the website and I don't receive any notification.
Thanks for any help !
Your question leaves a lot of missing information so I will go through each option for you:
Read here about how to setup a sandbox account if you don't already have one: https://developer.paypal.com/docs/classic/lifecycle/sb_create-accounts/
Bare in mind that your sandbox account is entirely separate in every way from your live paypal account. All settings will need to be checked and customised as needed.
Set up your IPN URL on your sandbox account Here: https://www.sandbox.paypal.com/uk/cgi-bin/webscr?cmd=_profile-ipn-notify
Once set up, you then need to download and set your code (PHP or something else) to the listener (referenced in the above sandbox profile link). You can find IPN code examples here: https://github.com/paypal/ipn-code-samples
When that's all set you need to set your listener to using the sandbox mode and then log in to your live account and then run the IPN simulator from here: https://developer.paypal.com/developer/ipnSimulator/
Paypal will send messages to your IPN listener and you need to do something with the messages, typically output them into some sort of log file. Any issues, you can read Paypals feedback and IPN data/delivery information here https://www.sandbox.paypal.com/uk/cgi-bin/webscr?cmd=_display-ipns-history&nav=0.3.4 [Found from History->ipnHistory on the Paypal menu] and it should list them out. You can resend any failed or queued or undelivered messages.
Paypal is a terribly documented and terribly structured system for coding with. I hate it. Use Stripe.
I love bullet points.
Paypal claims they will try and resend failed/queued IPNs 16 times over 5 days. I have yet to see this, you need to resend them manually (at least, sandbox ones)
Please remember all the settings and changes you have made to your Sandbox account will need to be also made to your live account before you make your payment system live!
Solution
My return_URL is the location of my IPN.php file which take care of the data sent and received. My problem is that the IPN is only firing when I click the "Return to merchant website" and not when the payment is actually completed
What you have done, from reading your comments, is set your IPN page to being your return from paypal page, this is NOT the way IPN is supposed to work, the IPN page should never be visited by the customer, only ever by Paypal.
Read through my anwser (points 2,3,4) and set up your IPN web link as I have described above, your return_url value should be a basic page to say to the customer "transaction complete". The IPN page is defined on your paypal accounts (sandbox and live) as I stated above.
This will fix your problem.
We have this website that was running since September 2013 and relying on paypal IPN for user registration. However, this week we got a report from the client where 3 users was able to pay through paypal but was not registered into the site.
We temporary changed the paypal email('business' field) from the client's to another paypal account. Went through the process of registration and the IPN was successfully delivered. The user was created in the system, the IPN transaction was logged into our system. When we tried to changed it back to the client's paypal email account, but unfortunately the IPN did not reached through our system.
Here are some questions that I have in mind
Does the type of paypal account (ie. business or personal account) matter when sending and receiving IPNs? Could this be a possibility? (even though last year it was working perfectly fine with the client's paypal account)
We've been receiving this paypal email (below) for the past months. That email was appearing after a few months when we opened the site and we didn't even changed a single code from our IPN listener. Could this be the reason why the IPN was not sent when we use the client's paypal account? However, we always use the notify_url field since we have multiple IPN listeners.

Your IPN script is not completing successfully, so PayPal's server is not getting a 200 result back, which causes it to send repeat IPN's and will eventually disable itself as the message says.
Your web server logs should provide the info you need. Check there to see the history of the IPN script getting hit and you'll probably find some 500 results. Those should also provide the actual error that happened so you can get it resolved.
It's possible that some IPN's are working just fine but others are failing based on certain characters in payer information or other similar issues. You need to get all of that worked out in your IPN script so it can handle anything thrown at it.
On the introduction of PayPal Invoicing API documentation it states that.
PayPal sends IPN messages for invoice payments and for invoices
cancelled by the buyer.
But I've found this is not the case. IPN for invoice payment, cancel or other operation never get sent from PayPal (I have checked and confirmed it from IPN history page).
Worth Mentioning
Invoices are being created via Invoicing API successfully without any warning.
I am working on Sandbox and Creating for Third Party Merchant.
I do understand that paypal doesn't send IPN for api operation changes.
The IPN listener is working fine and I have successful implementation for subscription api with IPN.
Update
Today I tried the whole process with Live PayPal account other than sandbox account and I still not getting any IPN. So, I guess I am doing something wrong or Invoicing API is broken (which I highly doubt).
Which also makes me wonder about some additional questions:
I (merchant #1) has the permission information form merchant #2 for sending invoice to their behalf.
I have setup IPN to my IPN listener URL.
merchant #2 do not have IPN setup to my listener URL.
So, when Invoice that I created for merchant #2, Do I get IPN?
OR, merchant #2 also needs to setup their IPN url pointing to my listener URL?
IPN is get send from the account that receiving payment as #effone mentioned in comment. So, it seems I was confused from paypal documentation.
Answer: The IPN url from merchant #2 will need to setup in order to get notification about invoice payment. merchant #1 account who sending the invoice behalf of merchant #2 will not send any IPN as the payment isn't involves merchant #1
Way I see it, this is not a proper solution to create an invoice management system. As if I have 1000's of user they all need to set their IPN url to mine in order to get the application work correctly (aka, setting invoices as paid when they gets paid)
Your question reads strangely, because you say the IPN is working fine, then in your update, you say you're trying it in your live PayPal account. It sounds like it's working on the Sandbox, but not in production?
If this is the case:
Did you activate the IPN under your Production (Live) Paypal account?
Do you have the IPN URL for this?
Are you seeing the IPN being logged under the Production (Live) PayPal site?
If No -> it's been a while since I've worked with this, but there used to be an interface where you could send an IPN test- have you tried that?
If Yes -> make a bare bones listener- just a page that logs that it was hit, then add logic to it.

I got an email from paypal saying:

Is anyone familiar with this? We got 1 payment that made through today, it updated the database and all but still I am concern if this email will be a threat to our website.
I tested the IPN url using the IPN stimulator and it worked fine. Should I need to change my IPN setting? Some forums are saying to turn off the IPN notifications. Should I assume that this is coming from the server refusing to accept the Paypal IPN? I'm so confused on what to do with this problem, let alone my client also knows.
I checked my site error logs but I couldn't find any new errors related to the my paypal IPN listener.
thanks,
If the warning message you are receiving is showing "url--", you may want to double check:
- the value set up in your PayPal Profile > Instant Payment Notification
- or the value you have inserted in your integration in the variable "notify_url" (if you are using Website Payment Standard or "PAYMENTREQUEST_n_NOTIFYURL" (if you are using API).
When you receive an IPN warning message, I'd recommend to check your IPN history (in your PayPal account) to check what is the HTTP response that your server is returning to PayPal.
