If those tracking parameters are missing, Boxly:
cannot tell where the lead came from
cannot show correct reports
cannot send conversions back to Google or Meta
marks the lead as “Direct Traffic”
Most tracking issues come from missing the GCLID or FBCLID.
This URL must include the tracking tags that Google & Facebook add.
Example correct Google Ads URL:
Example correct Facebook Ads URL:
If your URL looks like this:
https://www.yoursite.com/braces
or this:
Then Boxly has ZERO tracking information and cannot send conversion events back to platforms.
Below are the requirements for every common way leads enter Boxly.
What Boxly needs:
Nothing from you.
Boxly automatically receives:
Meta Lead ID
FBCLID
All tracking data Facebook provides
What Boxly can send back:
✔ Conversion events → Meta (Facebook & Instagram)
❌ Conversion events → NOT sent to Google Ads
Example (you do nothing)
User submits a Facebook Lead Ad → Boxly receives:
Meta Lead ID: 743819232 fbclid: FB.1.abc123 utm_source: facebook utm_medium: cpc utm_campaign: whitening_jan
This is the best method for accuracy.
If you send users to a landing page BEFORE the form submission, the landing page MUST capture the FBCLID.
Most people forget this.
If the landing page form does NOT send the FBCLID → Meta cannot optimise your ads.
What Boxly needs:
✔ The full form submission URL including FBCLID
Example of a correct submission:
https://www.yoursite.com/braces-offer?fbclid=IwAR1Xyz123&utm_source=facebook&utm_medium=cpc&utm_campaign=braces_offerIncorrect (most common error):
https://www.yoursite.com/braces-offer
If you send the second version →
❌ Boxly cannot send conversions to Meta
❌ No attribution
❌ Reporting breaks
Why?
Because Meta requires FBCLID to match the lead back to the ad.
Same logic as Facebook, but Boxly needs the GCLID.
If the gclid is missing:
❌ Google Ads cannot receive conversions
❌ Boxly reports will be wrong
Whatever form builder you use (WordPress, Webflow, Swipepages, Unbounce…), your form MUST send the FULL page URL.
Correct:
Hidden field → “Page URL” → send it to BoxlyExample submission data:
Entry URL: https://www.yoursite.com/veneers?gclid=abcd123&utm_source=google&utm_campaign=veneers_janIncorrect (most people send this):
Entry URL: veneers_formor
Entry URL: https://www.yoursite.com/veneers
This BREAKS tracking.
This is where most leads get labelled incorrectly.
Boxly requires:
✔ Map your “Page URL” → Boxly “Submission URL”
Correct example:
Zapier mapping:
• Landing Page URL → Submission URL
• Referrer URL → Submission URLValue passed:
https://www.yoursite.com/invisalign?gclid=123abc&utm_source=google&utm_campaign=invisalign_janIncorrect example:
Submission URL = (empty)or
Submission URL = Invisalign Form
If empty →
❌ Boxly marks lead as Direct Traffic
❌ Cannot send conversion data to Google
❌ Cannot send conversion data to Meta
❌ Cannot send conversion events back to Facebook
Reason:
FBCLID and Meta Lead ID do not come through Zapier.
Example of what actually arrives in Zapier:
Name: Sarah
Phone: 07123456789
fbclid: (missing)
Meta Lead ID: (missing)
So Meta cannot match the lead back to the ad.
If you use Boxly’s API, you MUST send submission_url.
Correct:
submission_url: "https://www.yoursite.com/implants?gclid=123abc&utm_source=google"Incorrect:
submission_url: "implants_form"or missing completely.
If missing → Direct Traffic → no optimisation.
