SMS API and SMS Gateway API Documentation

The TextUs SMS API is a RESTful API that allows your company to integrate your TextUs messages and contacts with your CRM or any other tool. The majority of functionality within our web application is accessible via the API, so the integration possibilities are endless.

The TextUs SMS API service supports HTTP Basic authentication. To authenticate, base-64 encode your username and api key (separated with a colon) and place the result in an ‘Authorization’ header. You may authenticate with your username and password, or with your username and API key.

An even easier and faster way to add SMS to your software.

Don’t let technology come between you and the people you’re trying to reach. With TextUs’s embedded messenger and white label texting, SMS is a seamless extension of your current suite of offerings. Rather than build out a proprietary texting solution, let TextUs do the heavy lifting. We’ll take our industry-leading conversational text messaging platform and make it look, feel and function like your own.

TextUs is business texting designed to work seamlessly with your current workflow and drive increased engagement with real-time, conversational communication.
