Capsule API for Developers

Phillip Haines posted in Product September 23, 2009

This blog post was written before Javelin was renamed to Capsule. See this post for more details.

We’re pleased to announce the Capsule API is now available. Developers can use the API to access Javelin whether you’re planning on creating a clever add-on you want to share with the community or hooking in one of your internal applications. The API is implemented using XML or JSON over plain old HTTPS allowing developers to use existing tools and languages.

The API closely follows RESTful principles with every resource like person, opportunity or tag having its own URL. Resources can be manipulated using standard REST commands GET (view), POST (create), PUT (update) and DELETE. For more details and to get started visit our API guide.

We would love to hear ideas you have on how you plan to use the API. Drop us a note at
