It is possible to simulate Teamwork Cloud projects on the server by using REST API. The topics below describe all available REST API requests and provide examples of how to use them. Prerequisites Before starting the simulation, make sure you have prepared your projects for server-side simulation. REST API documentation For more information about simulation-related REST APIs, see our REST API documentation in Swagger. There you can find REST API descriptions in both machine-readable and human-readable formats. REST API documentation is also provided with the installation of Cameo Simulation Toolkit with server-side simulation functionality. You can find it at http://<IP>:<Port>/simulation/swagger/index.html. GET /simulation/api/projects POST /simulation/api/run/project/<project>/version/<version>/branch/<branch>/element/<element_id>/config/<config> The following table describes the parameters used in the REST API request: Starts the simulation automatically after the initialization phase is completed. Available values are: false - only the initialization phase of the simulation is performed. The simulation then waits for an invocation to start the simulation, perform a step, or terminate the simulation. Commits a new project version with the simulation results. Available values are true or false (default). Returns the selected verification results. Available values are: The set of input parameters with values that should be provided for the simulation. Input parameters can be the parameters with the data type, primitive type, or enumeration type. The set of output parameters that should be obtained after the simulation is complete. If no output parameters are specified, all initialized values are returned. Output parameters can be the parameters with the data type, primitive type, or enumeration type.
