Marketing integration
Kit integration for AI workflows.
add subscribers to Kit, tag them and start forms and sequences from any workflow.
In short
Fluxo Flow connects to Kit with an API key or credentials you provide; workflows can create or update a subscriber, tag a subscriber and add a subscriber to a form and more, and start from new subscriber. The integration is live.
Live means tested end to end against real accounts. Found a problem? Tell us.

How to connect
Connect Kit in a minute.
Connects with an API key or credentials, tested before they're saved and encrypted at rest.
- In Kit, open Settings → Developer and, under V4 Keys, click Add a new key.
- Name it (e.g. “Fluxo Flow”) and copy the key right away; Kit shows it only once.
- Open Settings → Integrations here, click Connect on Kit and paste the key.
Permissions & limits
What it can access, and how fast it runs.
Permissions requested
Everything: a Kit v4 API key can use every endpoint this connector calls (Kit keys have no scopes)
Limits and timing
- Polling triggers are checked on your plan's schedule interval: Basic every 15 minutes, Pro every 5 minutes, Business every 2 minutes, Elite every minute.
- Kit triggers check at most every 5 minutes, whatever your plan, to respect Kit's limits.
- If Kit says to slow down (HTTP 429 or 503), requests wait as told and retry a limited number of times.

FAQ
Kit questions, answered.
Does adding someone to a double opt-in form send a confirmation?
Kit's docs don't say for this step, so check with a test address. To let Kit handle consent, create the subscriber as Inactive, then add them to the form; to skip opt-in, create them as Active only when you already have consent.
Why does tagging fail with “not found”?
Kit only tags, adds to forms and adds to sequences people who already exist. Put “Create or update a subscriber” before those steps.
Does it update an existing subscriber's details?
When the email already exists, Kit updates the first name only; custom fields and state aren't changed by that step.
Is the Kit integration ready to use?
Yes. Kit is live: connect it in Settings → Integrations on any plan, including Free (on Free you can build with it and Dry Run; running it live needs a paid plan).
Can I call Kit endpoints the integration doesn't cover?
Yes, if Kit has an API: save a key in the encrypted credential vault and call it with an HTTP Request step.
Can I test a workflow without touching my real data?
Yes. Dry Run walks through every step with simulated app calls, so nothing is sent until you run it for real or activate its trigger.
