We have integrated paypal express checkout in our application 1 year back and it was working just fine till last week. It still works fine on Live environment, the issue is with sandbox.
We get below error
The Request was aborted: Could not create SSL/TLS secure channel
On doing some search I found that there are some changes on Pyapal API. I did changes in endpoint as mentioned in API document but still it doesn't work. Anybody is facing the same and it would be great if you can give some working sample with new API changes.
