Messaging API

We offer a simple yet powerful suite of API methods to empower your developers with the ability to send and receive SMS from within your application. There are a vast number of use cases for SMS within most businesses and we make it as easy as possible for you to get started.

Our platform is lightning fast and available handsets will be notified within seconds (literally). It's hard not to notice an SMS!

The introduction of SMS capabilities into your platform enables you to develop complex interactions that simply aren't possible using other means. Using our API your development team can rapidly integrate SMS into your web app. Messages can be sent to many contacts in a single request and we will provide a callback for real time delivery notifications.

One Time Password

You have probably encountered one time password security features as many popular websites and service providers race to protect their customers data from unauthorised access. This type of authentication has been around for decades, with hardware devices often used to automatically generate and invalidate passwords, however this model has been too costly for all but the largest service operators to implement.

Now, with the price of sending SMS dropping dramatically we are able to offer affordable implementations for companies of all sizes. Password security alone simply does not offer adequate protection against determined individuals looking to gain access to your customers sensitive data. Using our simple and cost-effective OTP service you can provide your customers with confidence that you take their security seriously.
