Where Clausi sends your flows

Six platforms get one-click template push with your own API key (Clausi never stores it server-side). Everything else is reachable through the webhook: your n8n, Zapier, or Make workflow receives the whole flow as JSON and routes it anywhere those tools connect.

Klaviyo

Templates land in your account with subjects set, plus a step-by-step guide to wire the flow and the exact segment definition to paste.

You bring: Private API key (pk_...)

Mailchimp

Every email arrives as a saved template, ready to drop into Customer Journeys.

You bring: API key from Account, Extras, API keys

Omnisend

Guided setup with the paired SMS flow included. Omnisend runs both channels from one automation.

You bring: API key from Store settings

HubSpot

Marketing emails created via your private app token, editable in the HubSpot email editor.

You bring: Private app token (pat-...) with content scope

Brevo

Templates ready for campaigns and automations, subjects already set.

You bring: API key from SMTP & API

MailerLite

Key-verified guided setup: download the HTML here, paste it into your automation there.

You bring: API token from Integrations, API

Webhook: n8n, Zapier, Make, or anything with an HTTPS endpoint

Pick Webhook as the push destination and paste the URL from your trigger (an n8n Webhook node, a Zapier Catch Hook, or a Make custom webhook). Clausi POSTs the payload below on every push. Keep the workflow active and every future flow lands in it automatically.

Sample payload

{
  "source": "clausi",
  "event": "flow.generated",
  "sentAt": "2026-07-04T17:00:00.000Z",
  "brand": {
    "name": "Summit Coffee",
    "industry": "food_beverage"
  },
  "flow": {
    "name": "Abandoned Cart",
    "type": "abandoned_cart",
    "emailCount": 3,
    "emails": [
      {
        "position": 1,
        "subject": "your beans are still in the cart",
        "subjectVariants": [
          "your beans are still in the cart",
          "still thinking it over?",
          "about your cart."
        ],
        "previewText": "Roasted to order, ships within 48 hours.",
        "sendDelay": "1 hour after trigger",
        "purpose": "Recover the cart by removing the freshness doubt.",
        "body": "you left some beans behind...",
        "html": "<!doctype html>..."
      }
    ]
  }
}

Field notes

flow.emails[].html is a complete, styled, ready-to-import email with your logo and brand color already rendered.
subjectVariants holds the A/B/C options; subject is the one Clausi rates strongest.
sendDelay carries the research-backed timing for each step, as human-readable text.
Personalization tokens use Klaviyo syntax ({{ first_name }}); map them to your platform's merge tags in your workflow.

Requirements

HTTPS URLs only, and the endpoint must be publicly reachable.
Delivery is one POST per push with a 15 second timeout; answer with any 2xx.
Webhook push is available on Pro and Agency plans, like the other destinations.

No platform at all? Download every email as ready-to-import HTML or copy the whole flow as text.
