Track leads and sales from your links and QR codes

Connect a click on a CodeQR link or QR code to the sign-up and the sale it produced — what the chain needs, which plan, and where the results show up.

Click counts tell you which link got attention. Conversion tracking tells you which link got paid. CodeQR ties a click to the person who signed up and to the amount they spent, so a campaign report ends in revenue instead of traffic.

Availability

  • Plan: Pro and above. A 14-day trial is available once per workspace, and some older workspaces have it enabled from an earlier release.
  • Where: the Conversion tracking switch in the link and QR code builder, and Settings → Conversion tracking.

Turning the switch on without the plan is refused with the exact reason: You can only use conversion tracking on a Pro plan and above. Upgrade to Pro to use this feature.

The three events

Everything rests on one identifier, the click id, which CodeQR issues when someone opens your link.

  • Click — recorded by CodeQR on its own, with no work from you.
  • Lead — someone identified themselves: signed up, filled a form, started a trial. Your server tells us, quoting the click id.
  • Sale — money changed hands. Again your server, or the Stripe integration.

The asymmetry is the thing to understand before anything else: clicks are counted for you, leads and sales are reported by you. That is why a workspace often shows plenty of clicks and no conversions — nothing is broken, the second half was never wired.

What happens when you turn it on

The Conversion tracking switch in the link builder, turned on

With the switch on, the redirect changes in two ways:

  • The destination URL receives ?cq_id=…, so your site can read the click id even before any script runs.
  • The cq_id cookie lasts 30 days instead of one hour.

Both are how a click in August can still be credited for a purchase in September.

What you need to set up

  1. Turn the switch on for the links and QR codes you want measured — Set up conversion tracking on your website.
  2. Install the script on your site so the click id is stored in the browser. Same article.
  3. Report the lead and the sale — Send lead and sale events from your server, or let the Stripe integration do it in Attribute Stripe payments to the right link.
  4. Read the results in See which links and QR codes generate sales.

Where the results show up

Customers is the clearest view: each person, where they came from, and a timeline of everything they did.

Each link and QR code also carries its own counters — clicks, leads, sales and revenue — which is what turns a campaign list into a ranking by money.

About the API

Domain management aside, conversions are the part of CodeQR most often driven by code. Two endpoints do the work:

curl -X POST https://api.codeqr.io/track/lead \
  -H "Authorization: Bearer codeqr_xxxxxxxxxxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"clickId":"qcdyQHsX1oajEock","eventName":"Sign up","customerExternalId":"user_123"}'

An AI assistant connected over MCP can read your conversion totals but cannot record events — recording is deliberately left to your server.

Verify it works

After a full round trip, ask the link for its counters:

curl -sS "https://api.codeqr.io/links/info?domain=go.example.com&key=summer" \
  -H "Authorization: Bearer codeqr_xxxxxxxxxxxxxxxxxxxxxxxx"
{ "key": "summer", "trackConversion": true, "clicks": 1, "leads": 1, "sales": 1, "saleAmount": 4990 }

saleAmount is in cents, so 4990 is $49.90.

Troubleshooting

Clicks are growing and leads stay at zero

Nothing is reporting the leads. Clicks are recorded by CodeQR; leads and sales arrive from your server. See Send lead and sale events from your server.

The switch is disabled on a static QR code

A static QR code encodes the destination directly, so no click passes through CodeQR and there is nothing to attribute. Use a dynamic QR code.

I turned it on after the campaign started

Only clicks that happen after the switch is on carry the long-lived click id. Earlier clicks keep the one-hour cookie and are unlikely to be credited.

The sale is recorded but the link shows no revenue

Check the currency and amount you sent: amount is in the smallest unit of the currency, so 49.90 means 49 cents, not $49.90.
