It looks like the old IPN sandbox endpoint is no longer working again.

 

Instead of this:

 
Use this:
 
And it's working again. This was not the case a day ago as I tested both URLs when I noticed the IPNs were not coming through.
 
So not sure what changed?

Hello,

so how VA23 told:

yesterday I changed the Sanbox Endpoint 

 

from

https://ipnpb.sandbox.paypal.com/cgi-bin/webscr

 
to this:
 
Justin, could you confirm that the endpoint url has changed?
If so, where is this documented?
 
The Example Code hasn't changed.
 
So  the IPN Simulator now works fine. Befor I got an BAD REQUEST Error.
But that doesn't solve the problem, that no IPN messages are sent from PayPal.
 
Bernd

Hi all:

 

We were always using https://www.sandbox.paypal.com/cgi-bin/webscr 

 

We've given up on the sandbox, though, and are now testing on the live platform with prices set to just a few cents.  I must say I'm completely unimpressed with the sandbox and with the lack of support for this issue.

Hello,

You can use either of the endpoints for IPN validation.

"https://www.sandbox.paypal.com" or "https://ipnpb.sandbox.paypal.com". Both are always active, one did not replace another.

Due to an issue with IPN validation returning initially a HTTP 400 and now a HTTP 403 error with the "https://ipnpb.sandbox.paypal.com" endpoint, I recommended in another post where the issue was first reported to use "https://www.sandbox.paypal.com" for validation whilst we investigated the issue.

Hello,

Thanks for the update.

I've asked the IPN team to take a look at this, as it was working when I posted the response above.

I'll revert back here once they've confirmed it's been resolved.

Thanks

Hello,

 

my merchant id in sandbox is 4VEX8DNAVZ9BJ

I see the IPN message is sent to my IPN post back url. But, the PayPal response is empty when I receive it. It was working before (for a few years now) and not sure if something changed. However, IPN simulator is able to successfully post to my URL.

 

Our server supports TLS1.2 and when I open connection with PayPal, I get the following exception java.lang.ClassNotFoundException: com.ibm.jsse2.SSLSocketFactoryImpl; java.lang.ClassNotFoundException: com.ibm.jsse2.SSLSocketFactoryImpl

Here are the supported protocol versions - [TLSv1.3, TLSv1.2, TLSv1.1, TLSv1, SSLv3, SSLv2Hello]

 

When I run the TlsCheck.java, get inputstream from https://tlstest.paypal.com connection is empty (PayPal_Connection_OK message is not present). Please help. Let me know if any other information is needed.

 

Thanks.
