Quickstart: your first identified visitor in 10 minutes
Create an account, add your site, paste one tag, and connect a destination.
1. Create an account
Go to Start free. You get 100 credits every month and unlimited company-level ID. No card needed.
2. Add your site
Onboarding asks for your domain and whether you're B2B or ecommerce. You'll get a site key that starts with site_.
3. Paste the tag
Put this in the <head> of every page, replacing the key with yours:
<script async src="https://cdn.wholayer.com/t.js" data-site="YOUR_SITE_KEY"></script>Using a site builder? See the guides for Google Tag Manager, Shopify, WordPress, Webflow, Framer, or Next.js.
4. Try it in sandbox mode
New sites start in sandbox mode, which shows clearly fictional test people (on example.com addresses) so you can see the whole flow without spending credits. Visit your own site and open People in the dashboard. Read sandbox vs live.
5. Connect a destination
Under Destinations, add Slack, a webhook, Klaviyo, or HubSpot. Use Send test to check it.
6. Go live
On Sites, turn sandbox off. From then on, real matches appear and spend credits.
