ClickSend aims to improve business communications with the use of messages, e-mails, and voice systems. The goal of the PHP SDK is to ease the integration of SMS messaging into desktop and mobile applications. The requirements for developers include PHP 5.0, CURL enabled, and a ClickSend account.
When I saw three new SMS APIs, Kinross, Oventus & Txttools added to our index I thought that I might as well dive into this telephony area a little more deeply. A few minutes of clicking and I learned just how ignorant I was about this space. My previous understanding of the texting service provider arena was based on limited exposure. I had only heard of Tropo & Twilio and I assumed that they were the main players with other SMS sites simply wrapping around them. It seems that just the opposite is true, and that there is a lot of fragmentation in this area.
