Square Online install guide

Add Velo to Square.

Install the Velo cookie banner and Google Consent Mode v2 on Square Online in minutes. One line in the tracking tools panel does it. If you already run Google Tag Manager, that route is on this page too.

TimeAbout three minutes

Paste one line
into Tracking Tools.

One line in Square Online, and the banner is on every page with the Consent Mode default set before any other tag can fire. Same banner, same wiring and the same audit log as the Tag Manager route.

Already running Google Tag Manager? Take that route instead ↓

Three steps · about three minutes

  1. 01

    Copy the line

    One script tag, the same on every page of the site. Everything below is about getting it into the right place, and that place is always the head, ahead of the tags it governs.

    <!-- Before your other tags. That order is the point. --> <script src="https://veloconsent.com/v1/velo.js" data-velo-site="your-site-id" defer></script>
  2. 02

    Add the snippet in Square Online

    In the Square Online editor, open the site’s settings and add the snippet as custom header code under Tracking Tools. Custom code is available on paid Square Online plans.

    Publish the site

    Republish and reload the live site. The banner renders on the next page load with the Consent Mode default set before any other tag can fire.

One thing to watch

Square's hosted checkout runs on Square's own surface and does not execute site code. Velo captures the decision on your storefront, where the marketing tags actually live, and the stored decision keeps applying across the session.

Recommended if you run a container

Or import the tag
in Tag Manager.

One tag, no code on the page, and your whole measurement stack stays in one place. No Tag Manager yet? Square Online accepts a GTM container in the same tracking settings. Connect it, then start here.

Square Online questions,
answered.

What teams installing on Square Online ask first.

Which Square Online plan do I need?

Custom code on Square Online is a paid plan feature, the same requirement any tracking tag has. With that in place, either method on this page takes a couple of minutes.

What about Square’s hosted checkout?

The checkout runs on Square’s own surface and does not execute site code. Velo captures the decision on your storefront, where your marketing tags actually live, and the stored decision keeps applying across the session.

I already show another cookie banner.

Remove it before publishing Velo. Two banners confuse visitors, and two consent tools writing Consent Mode defaults send Google conflicting signals. One layer, one source of truth.

Will it slow the site down?

No. The script loads deferred, never blocks rendering, and the visitor's region is resolved at the nearest edge before the page finishes painting. The banner itself is a few kilobytes of static code.

Can an AI assistant do this for me?

Yes. Copy the prompt in Install with agents, just below, into Claude, ChatGPT, Cursor or whichever assistant you already use. It carries the steps on this page, the order the tags have to load in, and the checks the agent has to run before it tells you the job is done.

Or hand it
to an agent.

Copy the prompt into Claude, ChatGPT, Cursor or whichever assistant you already use. It carries everything on this page: both routes, the order the tags have to load in, and the checks that prove it worked.

The prompt

Paste it in as your first message, then swap your-site-id for the ID on your Velo dashboard. Everything else the agent needs is already written into it, including what to check before publishing.

Install prompt · Square Online
# Install Velo on Square Online: cookie banner + Google Consent Mode v2 You are installing Velo, a consent management platform, on my Square Online site. Velo shows the cookie banner, sets the Google Consent Mode v2 defaults before any other tag can fire, and records every decision. Ask me for these before you touch anything: - My Velo site id. It is in the Velo dashboard. No account yet? Send me to https://veloconsent.com/get-started and wait for the id. - Whether the site already runs Google Tag Manager, and which container. - Which cookie banner or consent tool is live on the site today. ## Path A: through Google Tag Manager (preferred when GTM is live) 1. Templates → Tag Templates → New, then ⋮ → Import. Import the template.tpl from github.com/ampliodata/velo-cmp ("Velo CMP"). 2. Create a tag from that template. Set my Velo site id and pick the light or dark theme. 3. Fire it on the "Consent Initialization – All Pages" trigger. Not Initialization, not All Pages. Both run too late to set consent defaults. 4. Preview, check the Consent tab in Tag Assistant, then Submit and Publish. No container yet? On Square Online, Square has no GTM toggle, so paste the container snippet under Settings → Tracking Tools → Add custom header code. ## Path B: the snippet, straight into the site Put this line in the <head>, above every analytics and advertising tag: <script src="https://veloconsent.com/v1/velo.js" data-velo-site="MY_SITE_ID" defer></script> On Square Online: the Square Online editor → the site's settings → Tracking Tools → add the snippet as custom header code. Custom code is available on paid Square Online plans. ## Rules - One path, never both. Two installs means two banners. - Velo loads first. Everything that measures or advertises comes after. - Only one tool may set Consent Mode defaults. If another cookie banner is showing, remove it before publishing Velo. Leave no hard coded gtag('consent', 'default', ...) anywhere else either. - Change nothing beyond what this install needs. Tell me first if a theme file, plugin or existing tag has to be touched. ## Verify, then report back - The banner renders on a fresh load in a private window. - Before I choose, every consent signal except security_storage is denied from an EEA, UK or Swiss location. - Accepting and rejecting each flip the matching signals, and a velo_consent_update event lands in the data layer. - Google tags stay in their cookieless mode until consent is granted, and any tag gated by hand fires only after it. - window.Velo is defined, and Velo.open() reopens the preferences panel. - On a Tag Manager install, Tag Assistant shows the Velo tag firing on Consent Initialization ahead of every other tag. Tell me what you changed, where you changed it, and what each check showed. If a check fails, fix it and run the checks again.
