Bulk SMS API Integration Service

What is SMS API Integration?

iSMS provides a fully documented SMS API (Application Programming Interface) that allows developers and businesses to integrate bulk SMS capabilities directly into their own software, websites, ERP systems, or mobile applications. Once integrated, your system can send, receive, and track SMS messages automatically without logging into the iSMS portal manually.

The iSMS API connects via HTTP/HTTPS, making it straightforward to integrate with virtually any platform or programming language. iSMS operates on a prepaid credit model — you pay only for what you send, with no setup fee or monthly subscription.
