Know where every lead
really came from.

Install it with two GTM tags

Library in one tag, settings in another. Simple to set up, safe to update later.

Tag 1 — Intake Library (Custom HTML, no trigger)

Paste the full library code from intake.plurio.ai. Don't edit anything here — updates are painless this way.

// Intake library v2.x — paste the whole block from intake.plurio.ai
// DO NOT EDIT. Configuration lives in the "Intake — Config" tag.
!function(t,e){/* …minified library… */}(this, function(){ … });

Tag 2 — Intake Config (Custom HTML, trigger: All Pages)

The tag you actually edit. Start with this recommended config:

intk.init({
  // Hash emails/phones from forms (SHA-256) — off by default
  pii_collection: { enabled: true },

  // Capture GA Client ID for BigQuery stitching — off by default
  analytics_ids: { google_analytics: true },

  // Push intk_ready event + intk_user_profile to dataLayer
  data_layer: true,

  // Consent: respect your CMP (OneTrust, Cookiebot, Didomi…)
  consent_mode: {
    enabled: true,
    default_consent: 'denied',   // no cookies until user clicks "Accept"
    url_passthrough: true         // pass UTMs via URL while consent denied
  }
});

Link them with Tag Sequencing

Open Config tag → Advanced Settings → Tag Sequencing. Check "Fire a tag before this tag fires" and pick Intake — Library. Turn on "Don't fire this tag if the setup tag fails". Save and publish.

Verify it works

Send the real traffic source with every form

The highest-value use case: your CRM stops saying "direct / none" and starts showing the actual campaign behind every lead.

1Create a trigger for intk_ready

In GTM: Triggers → New → Custom Event. Name: Intake Ready. Event name: intk_ready. Save.

2Create GTM Variables

Go to Variables → User-Defined Variables → New. Choose Data Layer Variable. Fill in the name from the table below.

3Pass the data with every form submission

Option A — Hidden fields in the form (works with any form builder)

Create a Custom HTML tag in GTM with trigger Intake Ready. It automatically injects hidden fields into every form on the page:

// Fires on trigger: Intake Ready
document.querySelectorAll('form').forEach(function(form) {
  var fields = {
    'utm_source':   intk.get.current.src,
    'utm_campaign': intk.get.current.cmp,
    'first_source': intk.get.first.src,
    'gclid':        (intk.get.click_ids || {}).gclid || ''
  };
  Object.keys(fields).forEach(function(name) {
    var input = form.querySelector('input[name="' + name + '"]');
    if (!input) {
      input = document.createElement('input');
      input.type = 'hidden';
      input.name = name;
      form.appendChild(input);
    }
    input.value = fields[name];
  });
});

The script finds every <form> on the page, creates hidden fields if they don't exist yet, and fills them with Intake data. When the user submits, the values go to your CRM automatically.

Option B — GA4 event parameters (if you send form events via GTM)

In your GA4 Event tag, add the GTM variables from the table above as event parameters:

Compare "first click" vs. "last click" in GA4

Most marketers only see the last click before conversion. With Intake you can send the first click too — and finally answer "which channel starts sales, and which one closes them?"

Add two custom dimensions to your GA4 conversion event tag:

first_touch = {{Intake — First Source}} / {{Intake — First Medium}}
last_touch  = {{Intake — Current Source}} / {{Intake — Current Medium}}

(Create Intake — First Medium: Data Layer Variable = intk_user_profile.traffic_attribution.first_visit.medium)

Quick data reference

Every path below is a value you can read via GTM variables or in the console.

Config options that solve real problems

The config above handles 80% of setups. Below are options you add when you hit a specific problem.

consent_mode: {
  enabled: true,              // wait for consent before storing cookies
  default_consent: 'denied',  // no cookies until "Accept"
  url_passthrough: true       // pass UTMs via URL while consent denied
}

user_id: { source: 'dataLayer', key: 'userId' }
