Hi,
Paypal IPN verification fails, I have multiple payments but 2 of them fails at IPN verification. I didn't changed my code.
Also I tested with PostMan, I got the data which I need to send back to PayPal from IPN History from my PayPal account, if you click on a message id, you will see a text box with some data. For a payment where IPN verification was successful, it was successful in PostMan too, but for the failing ones, Paypal is returning "INVALID". The data which I used for test can't be wrong because is from my PayPal account.
Where is the issue, the data which PayPal send it to me, and shows me in my account, is wrong? Or PayPal IPN verification method has a problem?
Thank you
