Developers have full access to the WinSMS API — tools that let you easily integrate two-way SMS messaging into your existing database applications, custom software and websites.
Full access to the WinSMS API
The WinSMS Bulk SMS API is available to developers and allows for the simple integration of SMS messaging into various platforms. Add SMS messaging to your existing database applications, as well as any custom software or websites.
Our SMS gateway supports FTP, HTTP, XML and POP3 (Email to SMS), giving you a flexible solution that meets most needs. WinSMS is aligned with all the major South African networks — Vodacom, MTN, Cell C and Telkom Mobile — so you also benefit from highly competitive rates with no network restrictions.
