Synced data

Date range

• Historical: Last 90 days on first sync
• Ongoing: Daily incremental sync

Attribution matching

TrustData matches Google Ads clicks to conversions:

User clicks ad → gclid captured → stored as trdt_cid
        ↓
User converts → conversion event sent
        ↓
TrustData matches conversion to click via trdt_cid
        ↓
Attribution credit assigned to campaign/ad group/ad

Conversion forwarding

TrustData can upload offline conversions to Google Ads via the Conversion Upload API. This feeds your first-party conversion data back into Google's bidding algorithms.

How it works

Google Ads OAuth tokens expire every hour. TrustData automatically resolves a fresh access token from your connected Google Ads data source — no manual token entry is needed.

Finding your customer ID

Your customer ID is the 10-digit number shown in the top right of Google Ads (e.g., 123-456-7890). Enter it without dashes: 1234567890.

Finding your conversion action ID

1. In Google Ads, go to Goals → Conversions → Summary
2. Click on the conversion action you want to use
3. Look at the URL in your browser — it contains a ctid parameter, e.g.:

   ...ctid=7175926768...
   

4. Copy the numeric ID (e.g., 7175926768)

Configuring in TrustData

1. Go to Settings → Attribution IDs → select your ID → Edit Tracking Config
2. Open the Forwarding tab
3. Under Google Ads Conversion Upload:
   • Enable Google Ads
   • Enter your Customer ID (without dashes, e.g., 1234567890)
   • Enter the Conversion Action ID (numeric, e.g., 7175926768)
4. Click Save Configuration
