Introduction: the role of SMS API in modern retail
In the fast-paced retail and ecommerce landscape, connecting instantly with customers is crucial. SMS API technology lets stores send notifications, promotions, and transactional messages to customers' phones, ensuring prompt, reliable communication. The result? Improved customer experience, stronger engagement, and increased sales.
What is an SMS API?
An SMS API (application programming interface) is a software bridge that enables businesses to integrate SMS sending and receiving into their own platforms. With an SMS API, retailers and ecommerce stores can automate notifications, streamline marketing campaigns, and personalize customer interactions—all programmatically and at scale.
