API Documentation

This documentation refers to our Legacy API, which is unavailable for new users and will be deprecated for existing users soon. Please check out our new API here.

Disabling TLS 1.0 & SSL encryption protocols on June 30th 2018 - What You Need to Know

As part of continuous improvements to our systems, we are disabling support for TLS 1.0 & SSL encryption. Only TLS 1.2 and above will be supported going forward. This is in accordance with Industry practice for improved security. Outgoing https connections from our servers to any customer server will be supported over TLS 1.1/1.2. After this change, you cannot connect to our APIs over TLS 1.0. Get the full story and next steps here.


Leverage the power of EZ Texting's flexible Bulk SMS API to allow your application to send text messages through our SMS gateway. Whether you're an independent developer or you work on a team at a Fortune 500 company, we're here to provide you with the right tools and the support you deserve. Our SMS gateway is robust, reliable, and easy to use.

We offer a REST API and a legacy HTTP API. While we will continue to support our HTTP API, this is a legacy product. Active development has moved to our REST API. As such, we encourage you to use our REST API. The REST API already offers new bulk sending and message scheduling options. No new features will be added to the HTTP API. Regardless of the API you choose, incoming messages are handled by our Incoming Message API.

Lastly, feel free to explore our C# SDK. You can download it from the NuGet package manager or directly from GitHub.

Read The Documentation

Before you begin working with our text messaging API you'll want to read through the documentation. We Offer REST & HTTP APIs. Please make sure to read the documentation for the API that you are using.

If you are sending the same message to multiple recipients our REST API allows you to pass us an array of phone numbers. The HTTP API requires you to loop through each phone number. The HTTP API is a legacy product.
