An SMS API is an application programming interface (API) that allows developers to integrate SMS messaging functions into their applications. It provides a simple way for interaction between the client application and the BSG platform. In simple terms, a REST API (Representational State Transfer Application Programming Interface) is a way for web services to exchange data with each other over the internet using the HTTP protocol and a convenient data format called JSON (JavaScript Object Notation). JSON is a simple text format that is easy to read and write for both humans and computers. You just need to send an API request with specific parameters to send a single SMS message or a Bulk SMS campaign, and our service will handle the delivery and provide a report.
API is a powerful tool that enhances communication capabilities, providing businesses with a reliable, scalable, and efficient method of reaching their audience.
We have libraries for PHP, Java, Python, Node.js, and other popular programming languages. You can view the full list in the GitHub repository at the following link.
To send a bulk SMS message through the API, you need to use the ‘Bulk SMS campaign’ method. In its parameters, you should specify an array with recipients’ phone numbers, the message text, message lifespan, and of course, the Sender name (phone number, short code, or alpha name on behalf of which the broadcast will take place). Additionally, you can use the ‘Send SMS to Contacts list’ method to avoid specifying the entire list of recipient numbers in the request. Instead, you only need to specify the list ID from your contact book.
SMS API gateway is a service that provides access to sending SMS messages through mobile carrier networks. It acts as an intermediary between applications and networks. SMS API Gateway and SMS API are not the same, although they are related. SMS API Gateway is the infrastructure that handles sending SMS, while SMS API is a set of instructions provided to developers to work with SMS messages through this infrastructure.
