Connect Kit (formerly ConvertKit) to ListFunnel.
Handles Kit's single-use refresh tokens automatically.
How connecting works
- 01Click "Connect Kit (formerly ConvertKit)" from ListFunnel's Connections page.
- 02Sign in and authorize on Kit (formerly ConvertKit)'s own consent screen — ListFunnel never sees your Kit (formerly ConvertKit) password.
- 03Kit (formerly ConvertKit) redirects back with an access token, which ListFunnel encrypts (AES-GCM) before it ever touches the database.
- 04Your Kit (formerly ConvertKit) connection shows as connected — subscriber sync activates from there.
What syncs

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.
