Getting Started

Set up Simmer in about four minutes — install the pixel, connect a CRM or store, see attributed revenue.

Simmer is a B2B marketing attribution platform. You install a small browser pixel on your website, connect HubSpot and/or Shopify, and Simmer stitches anonymous browsing sessions to CRM contacts and revenue events. The dashboard then tells you which channels actually drove the deal — not just the last click before signup.

What you'll set up

A project in Simmer — your tenant; everything below scopes to it.
The pixel on your website — captures page views, form submits, and engagement.
At least one conversion source:
- HubSpot — for B2B teams. Provides the conversion (form submit / closed-won deal) and the identity (email ↔ browser session).
- Shopify — for storefronts. Provides the conversion (order) and the customer email.
- Server-side Conversion API — for everyone else. POST from your Stripe webhook (or any backend) when a payment completes.
(Optional) Identity stitching for HubSpot — add a hidden simmer_id field to your conversion form so Simmer can link a contact to the browser session that created them.

Prerequisites

A website where you can add a <script> tag in <head>.
Admin access to HubSpot and/or Shopify (OAuth needs an account owner).
About 4 minutes.

Quickstart

Create a project

Sign up at the dashboard and create a project. Note your project ID (e.g. acme_demo) — you'll paste it into the pixel snippet next.

Install the pixel

Add this to the <head> of every page on your site:

<script
  src="https://app.letsimmer.com/pixel.js"
  data-project="YOUR_PROJECT_ID"
  data-collect-url="https://app.letsimmer.com/api/collect"
  data-identify-url="https://app.letsimmer.com/api/identify"
  defer
></script>

Replace YOUR_PROJECT_ID with the project ID from step 1. The pixel auto-tracks page views, form submits, scroll depth, and time on page once the user grants consent.

See Install the Pixel for SPA, CMP, and verification details.

Connect HubSpot or Shopify

In the dashboard, go to Settings → Integrations and click Connect HubSpot or Connect Shopify. You'll be redirected through OAuth and back to Simmer with the integration linked to your project.

For HubSpot, follow up by adding the hidden simmer_id field to your conversion form — this is what links anonymous browser sessions to the contact record.

See attribution

Once a real visitor lands on your site, fills out the connected HubSpot form (or completes a Shopify order), the conversion will appear in the dashboard within seconds, with the channels that introduced, assisted, and closed it.
