Required permissions

The OAuth flow requests these scopes:

• https://www.googleapis.com/auth/adwords - Read Google Ads data

TrustData only reads data. We never modify your campaigns or settings.

Synced data

Date range

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

Attribution matching

TrustData matches Google Ads clicks to conversions:

TrustData captures gclid only to forward conversions to Google Ads when the visitor consents. Consent masking drops it. It is never the attribution key.

Conversion forwarding

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

How it works

Google Ads OAuth tokens expire every hour. TrustData resolves a fresh access token from your connected Google Ads data source. You do not enter a token manually.

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
