I am trying to integrate paytm payment in my web app. i am following Paytm payment gateway

Till step two it's working fine. but at step three i am not able to post request with paytm URL by using react js --"Customer fills payment details and completes the payment authentication. Once the payment is complete, response is posted as HTML form POST on your app/website's callback URL"

How do i do this in react js only.

You should handle the call back response through backend as checksum need to verify. Also do the status query from backend before showing the success response to user
