Tropo.com The Tropo Web API is a web-service API that lets you build communications applications that run on your servers and drive the Tropo cloud using JSON over HTTP. It uses the same request-response model many web developers are already comfortable using, communicating with applications running on your own server, feeding requests and processing responses back and forth as needed. The WebAPI is particularly useful in situations where, for example, you need to use a custom library (or libraries), or need access to a SQL database. The WebAPI allows for the deep backend integration you may need, but does, however, require you have your own infrastructure, your own hosting, and your own servers already in place. Quickstarts Quickstarts are fast, easy to follow examples that exemplify the ease of use and simplicity behind Tropo's functionality. Each example will include code samples; typically, the code will include both JSON examples as well as examples written in the four most popular libraries:

Processing.org SMS API Bulk Message Send Captain Kirk was always demanding more out of his Chief Engineer on Star Trek by saying, “Scotty, we need more power.” While there is no limit on the number of inbound SMS messages your application can receive, Tropo’s 10 digit numbers are limited by the SMS carriers to sending 10 outbound messages per minute per number (UPDATE – this limit has been improved to 1 message per second, 60 messages per minute as of July 22, 2011). All 10 digit US SMS numbers have such a rate limit but it’s up to each API provider to adhere to their request. Our SMS Shortcodes, on the other hand, have no limit on outbound SMS messages but there is a leasing fee to acquire these “Warp Speed” numbers. Contact sales@tropo.com if you are interested! If you feel like Captain Kirk when using 10 digit numbers and you want more power but you are not ready to move up to our SMS Shortcodes, here’s a trick! Here is an example of how I was able to help a customer do this using Ruby:
