The API feature makes life simpler

“[SimpleTexting] connects with API, which makes my life simpler as I can use their system mix all my systems and use automation.

I have bad email deliverability, but 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.”

Tre W. G2

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. Capterra

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. Capterra

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.”

Verified User G2

Achieve your vision with our API

Our API allows even the biggest dreams to come true–including Times Square billboards.

When SmileDirectClub asked Tiger Party New York to grab people’s attention in Times Square, Tiger Party turned to SimpleTexting.

Using SimpleTexting’s API and keywords, Tiger Party enabled people to send a text to make people smile using the details on the billboard. Their messages would then appear on the billboard to make everyone in Times Square smile.

“Customers appreciate how smooth the process is from start to finish.” – CW Bruton, Estrella Tacos y Mas

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.
