We have a new version of our REST API with new and enhanced methods. Our time tracker also includes support for SAML-based single sign-on (SSO) authentication. Version 1.3 of the REST API is accessible by all customers. If you're interested in building and integrating your own custom application with ClickTime, check out our web services documentation.
If you're currently using an old version of our REST web services, check out our REST 1.3 documentation for information on what's changed. We encourage you to migrate as soon as possible. The old version is now deprecated and will only be accessible until September 15, 2015.
