I am stuck in a situation in which when a user registers, he/she get a confirmation SMS on his/her mobile number, and he/she able to confirm their application by replying to the confirmation SMS, be repling like YES/NO to that confirmation sms..
Is there any SMS gateway available which provides the suitable functionality, I mean an API which takes user input from sms reply..
thanks in advance
Twilio has the ability to receive sms messages.
