The Teamwork Cloud (TWCloud) REST APIs are the essential properties in TWCloud that allow you to query data about user accounts, roles, projects, and that provide access and basic operations for the resources.
The remainder of REST APIs supported in TWCloud are properly defined via Swagger, a formal specification for documenting REST APIs. In Swagger, you can find the description of the APIs in both machine-readable and human-readable format. TWCloud REST API documentation is accessible at http://osmc.nomagic.com. The API document is also bundled with TWCloud installation. You can access if from the url, https://<TWCloud IP>:8111/osmc/swagger.
