Popular topics
Whether you're an administrator or a tester, we have a variety of topics to get you started with API simulation.

You're an administrator and want to set up API simulation the first time? These are your next steps:
-
Check the system requirements.
-
Learn about key concepts and components in the Tosca Cloud architecture.
-
Set up your simulation environment.

Your administrator has just told you that API simulation is ready for you. These are your next steps:
-
Follow the instructions in the email to join up. Welcome!
-
Download the Simulator agent to get the API simulation schema file. This schema will help you to develop your simulations.
-
Create your simulations. You can do this directly in the simulation registry or with a text editor or any Integrated Development Environment (IDE) of your choice.

You are a tester or business user and would like to get an overview of all simulations and the related tasks? Check out these topics:
-
Go to the simulation registry and check out which simulations are currently running. You can manage them there directly.
-
Deploy your simulations to a Simulator agent and run them there.
-
Modify your simulations if you run into issues.
