Connect your client

One URL. Every client.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Kit, so you can see the experience inside your AI.

It does not authenticate your account with Kit. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Kit owners ask.

  • 01

    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.

  • 02

    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.

  • 03

    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.
