Can I see the health score for a specific account?

Yes! Use the `get_account_success_details` tool with the unique account External ID. The agent will return the churn score, health metrics, and current status from ChurnZero.

How do I check which success playbooks are currently active?

Use the `list_success_playbooks` tool. Your agent will fetch all configured playbooks, allowing you to identify which automation flows are currently running.

Where do I find my ChurnZero App Key?

Log in to ChurnZero, go to the **Admin** section, and look for **Application Keys**. You can generate a new App Key there for API access.
