Connect Kit (formerly ConvertKit) to ListFunnel.

Handles Kit's single-use refresh tokens automatically.

How connecting works

  1. 01Click "Connect Kit (formerly ConvertKit)" from ListFunnel's Connections page.
  2. 02Sign in and authorize on Kit (formerly ConvertKit)'s own consent screen — ListFunnel never sees your Kit (formerly ConvertKit) password.
  3. 03Kit (formerly ConvertKit) redirects back with an access token, which ListFunnel encrypts (AES-GCM) before it ever touches the database.
  4. 04Your Kit (formerly ConvertKit) connection shows as connected — subscriber sync activates from there.

Why this connection is scoped the way it is

Kit (formerly ConvertKit) uses a single 'public' scope today, with more granular scopes still in development on their side. ListFunnel's connection uses PKCE and correctly rotates Kit's single-use refresh tokens, so reconnecting is never required just because a token got used once.

Questions people ask

I have an old ConvertKit app authorized — does that still work?

Yes — Kit's legacy app.convertkit.com OAuth URLs still redirect correctly, so existing authorizations keep working under the new Kit branding.

Why would I ever get disconnected from Kit?

Kit issues single-use refresh tokens — ListFunnel handles the rotation automatically, but if a refresh ever fails after long inactivity, you'll get a one-click reconnect prompt.
