Error Handling For Custom Stripe Checkout

I am working on custom stripe integration(gateway).If i do payment using credit/debit card i am getting successfull json response with token id from this url https://api.stripe.com

Solution 1:

Checkout validates the card information with the issuing bank. If the information is invalid, then the error is displayed directly to the customer in the popup form and no token is created, i.e. with a custom integration, the token callback function is not called.
