What it does

What is the LeadTrackr API?

The LeadTrackr API is a simple REST endpoint you POST leads to from any source — a custom form, a backend service, a mobile app or a data warehouse. Each lead arrives with its full attribution attached: the click IDs (GCLID, fbclid), UTM parameters and campaign data that tie it back to the ad that drove it.

Once a lead lands, it behaves exactly like one captured through a form plugin: you qualify it in LeadTrackr (or let your CRM qualify it automatically), and LeadTrackr pushes the resulting conversion to your ad platforms. The API is the fallback that guarantees you can track leads from literally any system, even ones we have no native integration for — without exporting a thing.

The moment a form is submitted, LeadTrackr captures the lead with full attribution — the campaign, ad, keyword and landing page behind it. Qualify it with one click and follow the whole path, from the first ad click to the closed deal.

  • Every lead tied to its campaign, ad & keyword
  • One-click qualification, synced back to your ad platforms
  • The full path from form fill to closed deal

FAQ

Frequently asked questions

Send the lead contact details plus any attribution you captured on your side — the GCLID or fbclid, UTM parameters and the campaign that drove the lead. The more attribution you pass, the more accurately LeadTrackr can match the conversion back to the originating ad click. If you only have an email address, LeadTrackr can still use Enhanced Conversions matching.
A basic POST request is all it takes, so anyone comfortable with HTTP requests can wire it up in minutes. If you would rather not touch code at all, use our WordPress plugin or Google Tag Manager template instead — they capture leads without any custom development.
Yes. Once a lead is in LeadTrackr, the destination is independent of how it arrived. Leads sent via the API can be pushed to Google Ads, Meta and GA4 exactly like leads captured through a form plugin.
