When i try to place order using paypal payments method i got error like this paypal gateway has rejected request . Invalid token (# 10410 invalid token). i have double checked by backend credential. there is no problem. How to resolve this.
In my case, I modified in the configuration module:
- Backend -> System -> Configuration -> Payment methods -> Paypal -> Advanced Settings -> Enable SSL verification to Yes.
If it does not work I recommend, in paypal account, reset API credentials and update in magento.
I have seen this happen when the configuration change has not been updated and was able to fix by flushing the Magento Cache through the admin (both buttons).
Are you using PayPal sandbox? What PayPal checkout method you're using?
Please post the complete error message.
