Introduction

QRIOS USSD API is intended for developers, who want to create their own USSD apps. It's a quick and easy solution for creating and deploying USSD apps.

Why use it?

The main advantage of USSD API is the ease of use and expandability. USSD API offers the ability to create advanced USSD processes and integrate them with external services via REST or SOAP API. To start with, you get a free shortcode, which can be difficult to acquire by yourself. At once you will be able to use it and communicate with your USSD app by Qrios USSD API.

How does it work?

The end user has a feature phone with GSM access, thus can send and receive USSD messages. Such USSD messages then reach Telco providers, who then relay those messages to Developer's USSD Application via Qrios APIs. It's not a problem if the end users have MSISDNs in different Telcos, since QRIOS integrates with many providers of telecommunications services. Developer's App can then optionally integrate with external system via REST or SOAP API. Alternatively, it can integrate just with USSD Application created and managed by Developer via the QRIOS API.
