Frequent Questions

If you’re not a software developer, the concept of SMS API integration with third-party services may be somewhat difficult to understand, so you may want to look at these questions:

How to use the Uwazii MOBILE API

You can utilize the Uwazii MOBILE SMS API to obtain inbox and outbound message information, transmission/reception of SMS messages, contact lists, recurring text scheduling, bulk SMS processing, and template setup. This is how to start using the Uwazii MOBILE SMS Gateway API: (i) Register for an account to obtain your SMS API credentials. The login credentials for the Uwazii MOBILE web application are the same as those for the API credentials. (ii) Connect to the API endpoint and start writing your code.

What is an API

An application programming interface or API is a set of web-based application programming rules, standards, and instructions. Generally speaking, SMS APIs are released to the public to allow developers to use the API to power their services. The end user sees only one interface, but many APIs work together behind the scenes and integrate with SMS solutions to deliver a seamless experience.

Does Uwazii MOBILE provide public SMS API documentation?

Of course! Our team has produced an exhaustive SMS API documentation to help you construct your own messaging application through our infrastructure. Our documentation includes information on text messages, SMS emails, distribution lists, personalized fields, accounts and sub-counts, and 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, acess the API and connect with your code.
