The API feature makes life simpler

“I love that SimpleTexting’ connects with API, which makes my life simpler as I can mix their system mix all my systems and use automation. I have bad email deliverability, SMS helps me contact the client and let them know they have an email from us but that it may be in junk. It also gave us a platform to chat with clients in real time.”

Anybody can become a pro

“The interface is very friendly and the tools/features are pretty much standard and very helpful. Basically, anybody can become a pro and if you have access to a developer the API is also a great plus to integrate your current CRM system and keep customers well notified throughout the entire journey.”
Marcelo F.
Trust Signal Star Icon

Lots of helpful features

“API capabilities were one of the greatest reasons we switched but as we’ve used it more and more there have been so many other reasons like assigning texts to other users, the SimpleTexting app, texting templates, and scheduling… the list could go on and on.”
Stephen H.
Trust Signal Star Icon

Incredibly easy to use

“SimpleTexting is an incredibly easy service to use. The interface as well as the API options made this a great selection for our use case. I think the customer service provided is world-class and that has been a huge help as we got started and even when we had questions regarding SimpleTexting.”

What is an SMS API?

An SMS API is a special way for computer software to communicate with text messaging. It helps people add texting features to their apps or systems. This special software has a set of rules and functions that let people send and get text messages automatically.

There are SMS APIs for Java, HTTP, and PHP. Once you set up an SMS API, you can see the status of your messages, send and get different types of texts, and even see what people wrote back to you without needing a password.
Read our SMS API and REST API documentation to learn about the functions available with SimpleTexting’s API.
SimpleTexting provides unparalleled SMS and MMS coverage in North America. Our offerings help businesses reach customers and subscribers across the U.S. and Canada. We also cover Puerto Rico and some countries in the Caribbean.
