API Integration

API is an acronym for Application Programming Interface. This interface represents a series of programming commands that allow two software applications to collaborate with one another. Think of it as a virtual partnership or agreement between the two to streamline interactivity and, in many cases, improve the performance of the software being integrated. Many of the tools that we use on a daily basis, including Google and Facebook, are powered and enhanced by APIs working behind the scenes.


So, now you know what APIs are and why they can be so vital for the survival and success of modern businesses. But you might be asking yourself: why Txtwire’s API? There are a number of reasons why our API has emerged as one of the most advanced and robust in the industry. Here are just a few:

International Reach

Txtwire’s global network is massive, giving us access to over 700 mobile carriers in 190 countries throughout the world.

Connect to Existing Software

One of the factors that makes integrating with our API so quick and easy is the fact that it allows you to use our platform with the software that you already have installed on your system.


While our competitors charge for both inbound and outbound messages, integrating with Txtwire means that you will only be charged for inbound messages if the amount exceeds the number of outbound messages you have received.


Integrating with our API streamlines the entire process of sending messages and managing your mobile campaigns, automating critical functions so you can focus your attention on other things.


Txtwire’s web-based documentation also includes industry best practices and regulations for your convenience. We also offer full support and consulting on all API compliance issues.

Ready To Go!

You’ll be surprised how easy it is to integrate, even with no prior experience with SMS. Once you receive the credentials to use our API, getting started is a cinch! You’ll be up and using our system in a matter of minutes.

Save Time

The Txtwire API unifies and consolidates a number of different time-consuming functions in real time, so you can concentrate on running your business instead of on running programs.

Pick and Choose

An API integration with Txtwire allows you the freedom to pick and choose which features you would like to use with each of your short codes.

Multiple API Options

Txtwire’s API also offers developers a number of different programming languages and application protocols to utilize within their system. We support the .NET Framework developed by Microsoft in addition to the SMPP 3.4 protocol. This allows us to give you real-time delivery status updates through your SMPP bind. We also have custom TLV’s defined to help streamline and simplify the integration process for you. Whatever your language, we’ve got you covered.
