I am using a PayPal SandBox for testing purposes. All was working fine, but all of a sudden I stopped receiving the txn_id. I am using
$_POST["txn_id"]
to check whether it is a request or a response. Help Please.
I just realized that it is not about $_POST["tex_id"], the "notify_url" is not working in the PayPal response. It was working up till yesterday, not sure what went wrong. Any Suggestions?
I am having trouble testing IPN with Sandbox. I have been testing my setup with the IPN Simulator and that works very well. However when I make a test transaction using the Sandbox I get no output. I have looked in the IPN history and there is nothing shown there. I have also checked my url's.
I am new to this aspect of PayPal so there may well be something I'm missing. Any help would be much appreciated.

I need some help for this is not set on my side.
Please help me out on this.
Thank you in advance.
The handshake error is most likely to occur when your server/keystore config is non-compliant with the upgraded PayPal SSL encryption algorithms.
IPN simulator will connect againest the PayPal Sandbox environment, which has been upgraded with Versign G5 root cert / SHA-2 encryption algorithms (btw this is an industry standard as supposed to be everywhere in 2016).
Once your IPN host failed to meet the compliance, the SSL connnection will error out with handshake problems.
Simply check your server by running a connection script against the PayPal sandbox endpoint like this:
openssl s_client -connect api-3t.sandbox.paypal.com:443 -showcerts -CApath /etc/ssl/certs/
If you were not getting an Verify return code: 0 (ok), you would probably have to check the cert/SHA-2 compatibility, following the general instructions that PayPal has published here:
2015-2016 SSL Certificate Change Microsite
I was having the same issue. A workaround to test IPN messages would be to actually setup IPN notification URL on your Sandbox business account and test it from there.
Login to https://sandbox.paypal.com with your sandbox business account (sb-xyz#business.example.com)
Navigate to your Account Settings page
Website Payments
Update Instant payment notifications
set your notification URL there.
Make sure, your IPN listener is not behind firewall and is directly accessible from outside world.
PayPal's Response:
"Thank you for contacting PayPal Merchant Technical Services, I apologize for the delay in responding to your email.
We are aware of this issue with our IPN Simulator and our development team is working on a fix. Until this issue is fixed, I'd suggest running your IPN tests by making payments in Sandbox as we do send IPN requests with every payment.
If you have a similar issue with your payment tests, please let us know and we can take a look.
My apologies for the inconvenience caused."
I am not getting any IPN notification after successful Expresscheckout.
I have tried overwriting NOTIFY URL dynamically and by setting it through "My Setting tools" setting. But none of them hitting to url specified for IPN.
I am using sandbox accounts for making payments.
What is missing in here? Please help me out. Thanks in advance..!
This works perfectly fine if i use IPN Simulator for IPN testing...!
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.
