How do I find my Kit API Secret?

Log in to Kit, go to **Settings > Advanced**. Under 'API', click **Show** next to API Secret, copy the string, and paste it below.

Why is the API Secret required instead of the standard API Key?

The API Key only provides read access to public forms. The API Secret grants full access to manage subscribers, tags, and broadcast data as needed by this integration.

Can the agent send broadcast emails?

No. For safety, the integration is read/manage only. The agent can check campaign metrics and manage tags, but actual email sending must be done via the Kit dashboard.
