REST Endpoint: POST: https://rason.net/api/simulate

A REST API endpoint that accepts a RASON model, runs a simulation and returns a result in JSON format. This call should only be used with models that run very quickly, i.e. within a few seconds. There is a time limit of 30 seconds on all 'Quick Solve' calls.

• URL: https://rason.net/api/simulate
• Method: POST
• URL Params

  Required: None

  Optional: Any data component may be passed as a query parameter if a binding property exists for that data component. See the previous topic "Parametric Selection Feature" for a complete example illustrating how to pass a query parameter from outside or inside your RASON model.

• Headers:

  Required: Authorization - Example: Authorization: bearer {your RASON token}

  Optional: None

• Data Params Example: A RASON simulation Model.
