Paytm guys suggests to verify the transaction status manually after the successful transaction.

ENVIRONMENT info has to be part of 'options', which says the environment transaction has to be started. Possible values are 'staging' and 'production'.
Send transaction amount in String format, as that is the format accepted in iOS platform.
