Communication made easy with
Red Oxygen's API

With a short message service (SMS) gateway application programming interface (API), you can take advantage of your existing workplace databases to keep relay information via SMS. In this modern day, a text message is often the easiest way to grab your recipients’ attention. With an SMS gateway API integration, you can send pertinent information out without having to change applications, be that payment reminders, appointment notices, security codes or alerts.

What is an API?

Application program interfaces (APIs) allow databases and applications to communicate with each other. For example, if a hot tub reseller wants to display the weather from their local news station on their website, they would use an API to request the information from the news station’s weather database to then display on their site. Or maybe you utilize membership database software, and you’d like to send SMS to some of your members without having to leave the software interface…Red Oxygen’s API is the perfect solution.

APIs also add a layer of privacy and protection as the go-between that never allows the two to directly interface with each other.

Red Oxygen’s API SMS gateway consists of a core API, extended API and command API. Together, Red Oxygen can help you reach clients and customers faster than ever while giving your business an extra layer of privacy.
