We’ve recently updated the Capsule API pages. The API itself is more or less the same, there’s a few updates and we have improved the design and overall look and feel of the API documentation.
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.
We’ll be removing the old documentation shortly so you should update your bookmarks with the new URL. Check it out here: developer.capsulecrm.com
