In order to use the activeCollab API, first you will need to authenticate yourself to the system, which you can do using your API key. This key is available on the API Settings page of your activeCollab user profile:

When creating a request, the API key must be passed as a "token" GET variable. The sample request URL would then look like this:

http://example.com/public/api.php?path_info=projects&token=1-55lTBjCvCALC6Jksg3vo2xQeymySDqFwkReL1H8s
Note

Your API key can be reset at any time. All you need to do is to click the Reset Key link. Please also be aware that your API key will be automatically reset whenever you change your password!
