Why connect Klaviyo to n8n?

n8n runs on triggers and schedules, so a question you ask once can become a check that runs every morning. Connected through Lemonado, it reads your Klaviyo campaigns, flows, segments and attributed revenue, so it can catch a list that's wearing out with today's numbers.

  • All your Klaviyo data

    Email and SMS campaigns, ready to ask about.

  • Always today's numbers

    Opens, clicks, unsubscribes and spam complaints, synced from Klaviyo automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "Does Klaviyo over-claim?" use Klaviyo and Shopify, Meta Ads at once.

How to connect Klaviyo to n8n

Before you start

  • A Klaviyo account you can sign in to
  • n8n installed
  • A Lemonado account (the free trial works)
  1. 1

    Connect Klaviyo in Lemonado

    In Lemonado, open Connectors, find Klaviyo and sign in. Sign in to Klaviyo and pick the account. A user with access to campaigns, flows and analytics works best.

  2. 2

    Turn on external access

    In the company's settings, open External tools, turn the connection on, choose which sources it can reach and copy the server URL.

    https://mcp.lemonado.io/mcp
  3. 3

    Create a token in Lemonado

    In External tools, open your connection's guide, choose n8n, pick an expiry and click Generate Token. Copy it.

  4. 4

    Add the MCP Client Tool

    In your workflow, add an AI Agent node, then add an MCP Client Tool under its tools. Use node version 1.1 or later; version 1 only speaks SSE.

  5. 5

    Configure it

    Set the endpoint to the server URL, the transport to HTTP Streamable (pick it yourself on node version 1.1, which defaults to SSE) and authentication to Bearer Auth. Create a Bearer Auth credential and paste the raw token, without a "Bearer " prefix.

  6. 6

    Test and save

    Test the connection, save the workflow and ask the agent about your data.

  7. 7

    Ask n8n about Klaviyo

    Try "Every morning at 8, check yesterday's Klaviyo numbers and post anything unusual to #marketing." Or ask: "Did a flow stop sending?" or "How did the campaign land?"

Good to know

  • If the MCP Client Tool only shows an SSE Endpoint field, it's the version 1 node: replace it with a newer one. Keep the /mcp URL and choose HTTP Streamable.
  • Regenerating a token in Lemonado invalidates the old one, so update n8n when you do.

What can n8n do with Klaviyo?

n8n's AI Agent reads your Klaviyo data on a trigger or a schedule, then posts, logs or files the result in the next node.

Yes. Klaviyo's official MCP server is hosted, so n8n can use it too. It covers Klaviyo only. Lemonado covers Klaviyo plus your ad platforms, GA4 and the rest of your stack in one connection, so n8n can answer questions across them.

Use Test step on the MCP Client Tool. A 401 means the token expired or was regenerated, so paste a new one into the Bearer credential. In Lemonado, check that Klaviyo is connected and External tools is on for the company. If revenue is missing, check that your store sends orders to Klaviyo. Klaviyo can only attribute revenue to campaigns and flows when it sees the orders.
