Paste IDs from your platform's Ads Manager. For Meta: find them in the URL when viewing a campaign, ad set, or ad, or export from the Leads Centre. For Google: find them in Google Ads under the campaign/ad group/ad. Names are optional; the dashboard resolves them automatically.
Tracking tags appended to the ad's destination URL. If the lead came from a Meta Lead Form (no landing page), these are usually blank. Copy from the ad's URL or your UTM builder if available.
