There is one more route(Send OTP route) which is for Send OTP. If you are looking for OTP services, we would suggest you to opt for send OTP because it has various advantages over the traditional transactional route:

- We generate the OTP on your behalf, we send and we verify. You just have to call the APIs.
- The back-end algorithm makes sure that the OTP is processed from our end in less than half-a-second.
