  1. Is calling Fetch payment options mandatory?-

    The API call is used to create your cashier page where the paymodes will be displayed. If you are calling it when the user isn't logged into Paytm account, you can skip this call as the response will always have the same details except for NB channel details as the top 5 banks are shown on the basis of success rates. If the call is made when the user is logged into Paytm account, you should make this call as each user has different saved instrument and wallet balance.
