How do I find my Chuanyun Engine Code and Secret?

Log in to the H3Yun Portal, go to [Settings] → [Integration] → [API], and you will find your Engine Code and Engine Secret (API Secret) there.

What is a 'Schema Code' in Chuanyun?

A Schema Code is the unique identifier for a specific form or business object structure. You can find these codes in the application design section or by using the `list_forms` tool.

Can I see who approved a specific business object?

Yes. Use the `get_workflow_history` tool with the business object ID. It will return the detailed history of the workflow, including all approval steps and the users involved.
