Zapier provides a similar service to ifttt, that is to connect web services easily (via API, but without any programming knowledge).
For example, when you have a new Trello card, you can trigger to send a Twilio SMS.
I blogged about ifttt, and that an API might be coming. Zapier just done that.
I have tried adding my RESTful API to Zapier platform, and it took me just 1 hour. Our API wasn't even Perfect, and I took an additional minute to use their scripting API to make things work.
Awesome job, Zapier!
