I am integrating paytm in my android app using this documentation: PAYTM integration in android app
but when I am clicking on pay with PAYTM button it is showing following error:
Payment failed due to any of these reasons:
- Session expired due to inactivity
- Our system encountered an obstacle
You can fix it yourself! Here’s how:
- Clear cookies & temporary internet files of the browser
- Check payment status with your bank to avoid double payment
- Launch a new browser & start from the beginning
- Still unable to transact? visit us at?paytm.com/care
I am using PHP for backend services as provided in PAYTM documentation.
I am using send box credentials right now for testing purpose.
