What Is An SMS Gateway

SMS Gateway API

In computer technology terms, API provides a set of processes and tools that help build application software to make the process seamless – transferring from your email to a text message to the recipient’s mobile phone number. There are many different types of web application programming interfaces developed by SMS providers.

The term HTML and PHP should be understood. HTML is the information technology language that is used to explain to a browser how to display text in a browser window. It is not a programming language – HTML will work on your computer. PHP is different in that it is a scripting language used to develop web pages which will be written in HTML format.

To send SMS from PHP script you need to pick a reliable SMS gateway provider that will meet your needs. Once the SMS gateway and the way to proceed are complete, then the SMS integration of the gateway in PHP script can be completed by the SMS provider.


SMS Gateway API Integration In PHP

Millions of organisations use API integration as an easy way to improve the way business communication can effectively take place.  When distributing bulk SMS, this can happen by allowing you to connect from your own software or CRM directly into the provider’s sms gateway using their API platform. This way, by connecting via an API you will know that the text messages you have instructed the SMS provider to send using their platform will be done. After the delivery of the text message, you can request a receipt of the effectiveness of the distribution. This all takes just a few seconds, thereby saving you time and resources. Another advantage of the API system is that it can create and edit new user credentials.

Businesses can also choose to purchase a suitable phone number to use when send and receiving these text messages. These include short code phone numbers.

By engaging an SMS gateway API provider you will need to see the variety of options available to integrate your mobile messaging service seamlessly into their operations. APIs should provide the client in all aspects of their business whether it is applications, websites, intranets, CRMs or other software. Not only is integration important, but also reporting, accessibility and the ability to customise features or scripting to their APIs.

Take an example within the health sector, using an SMS gateway API, it will allow health professionals to:

  • Allow appointment rescheduling, should an appointment be missed
  • Alert for patient reminders
  • Alerts for emergency and incident thereby maintain open communications
  • Alert staff to fill shifts at short notice
  • Analyse traffic with real time analytics with regular delivery status reports
