Develop InfoBip USSD Platform/App

I want a USSD platform that will connect with my app. I prefer using InfoBip. So the workflow will be as follows: 1. Client dials, say, *123# 2. USSD session begins. 3. At the end of the session, the data is submitted to my app that I have created using Zoho Creator. I can provide API's for my Zoho App.
