4. To obtain or change data, add the desired operations in the **Integrations tab and actions**.
5. Check reading and changing the test entity before running on real clients.

Connection and actions are described separately. After authorization, go to [**Actions in integrations**](<../../actions/integrations/index.md>) to configure available operations and variables.
