i am using paypal express checkout integration in sandbox mode. I have followed the code given in paypal express checkout document. When i click on the payapl checkout button, it is redirected to paypal login page. But everytime i enter my email and password it shows "Some of your information isnt correct. Please try again later".
What account details are you entering on the checkout page ?
Check the URL shown in the address bar - If this starts with "sandbox.paypal.com" then you should be using a sandbox account to login to the checkout flow. If this starts with "www.paypal.com" then you should be using a production account to login to the checkout flow.
Account credentials between our production and sandbox environments are not interchangeable.
