Frequently Asked Questions

If you’re not a developer, the concept of SMS API integration with third-party services may be a bit difficult to comprehend, so you might want to take a look at these frequently asked questions:

How to use the Uwazii MOBILE API

You can use the Uwazii MOBILE  SMS API to query information about inbound and outbound messages, send and receive SMS messages, manage contact lists, schedule recurrent texts, process bulk SMS messages and create templates. Here’s how you can get started with the Uwazii MOBILE SMS Gateway API: (i) Register for an account to obtain your SMS API credentials. The login credentials for the Uwazii MOBILE Portal are different as those for the API credentials. Uwazii MOBILE has two SMS APIs (REST API v1 and v2 and SMPP API). If you already have a V1, please ensure that you upgrade it to V2, so that you are able to access our services efficiently. (ii) Connect to the API endpoint and start writing your code.

What is an SMS API

An application-programming interface or API is a set of programming rules, standards and instructions for accessing a web-based application. SMS APIs are generally released to the public to enable developers to power their services with the API. The end user only sees one interface, but behind the scenes, many APIs are working together and integrating with SMS solutions to provide a seamless experience.

Does Uwazii MOBILE provide public SMS API documentation?

Of course! Our team has prepared a comprehensive SMS API documentation that will help you build your own messaging app through our infrastructure. Our documentation includes information on sending, receiving and scheduling text messages, email to SMS capabilities, distribution lists, custom fields, accounts and sub-accounts, statistics, encoding and more. Read full SMS Gateway API documentation.

How can I obtain Uwazii MOBILE SMS API credentials?

Before you get started with the Uwazii MOBILE REST API, you have to register for an account which will give you your API credentials and connect to the API endpoint. This can be done by signing up for free. Once you have received your account credentials, download or read the API and connect with your code.
