A better documented fork:

It worked for me on Android. I still need to test on iOS

Answer 2

Make sure you are using the correct values of paytm parameters.
In your code, you are using APP_STAGING in website parameter. It should be APPSTAGING.
To check the correct parameters value of website parameter, follow the steps :-
Log into your Paytm dashborad - https://staging-dashboard.paytm.com
Go to settings->profile
Check value of Website
Also I need to add one more parameter to get it working i.e. mode:'stage'.
I am sharing my code that worked fine for me in android.
var details = {
mid: "my_mid",
industryType: "Retail", //Prod
website: "APPSTAGING", //prod
channel: "WAP",
amount: 100,
orderId: "ORDER_12390",
email: "abc#gmail.com",
phone: [phone],
custId: "CUST-12879",
checksumhash: "checksum generated using paytm sdk",
callback: "my_call_back_url",
mode:'stage',
};
// alert(JSON.stringify(details));
paytm.startPayment(details);
