Collaborate 4.4 is due to be released soon and in this release we have added several new API's. The list of the new API's can be found here.

All new API endpoints and changes have been completed under Collaborate API version 4 and all clients using previous versions of the API should not experience any change in their integration. We have upgraded our sandbox environment found here: https://integrationbeta.highq.com to Collaborate 4.4, so the integrators can test the integration with the new Collaborate version. For more information, the announcement for this was posted a few weeks ago. Please use the beta sandbox environment to test out these new API endpoints. 

Finally, please note that in order to keep the naming convention consistent, we have renamed the "location" tag to "address" in the Get User and Get User list API. Please consider this change when upgrading to version 4 of the Collaborate API.
