Whatever programming language you choose, we've got you covered
An SMS API (Application Programming Interface) is a set of tools which allows the capabilities of one computer application to be made available to another, so that SMS messages can be sent and received.
The API specifies how software components should interact and follows a set of predefined rules, allowing developers to build SMS-based workflows into their own applications.
How does an SMS API work?
An SMS API simplifies the whole process of sending a text from a system to a mobile handset.
It acts as a bridge between your organisation and your customers or members of staff.
The SMS API removes the hassle of having to write and deploy specific code to handle the complexities of multiple mobile phone networks that operate different protocols and infrastructures.
For a more in depth description, take a look at our simple explanation.
There are additional costs in integrating with the new supplier and there is always a danger that the new company doesn’t perform as expected. We understand these concerns and wanted to try and put a couple of fears to bed and explain why the benefits outweigh the risks.
In our experience, this is never as bad as feared. Most SMS API companies have similar approaches and often the code changes required are quite modest.
Our copy and paste code snippets go a long way to simplifying the process and we’re always on hand to help out if needed.
Customers tell us that above everything else, reliability is the single most important factor; even more crucial than SMS API price. We really understand this and we’ve put in the work to make sure that everything’s in place to provide the best SMS API online possible.
For a quick summary, take a look at our technical overview.
Paying for undelivered texts when your existing provider doesn’t, isn’t a very open way of operating.
By looking at your SMS delivery reports you’ll be able to see how much you’re currently spending on failed texts.
Over the course of a year, it’s likely to be a reasonable amount. Our delivered only pricing means you only pay for what’s delivered so there zero wastage.
