What you'll need
- A Google Ads account with Lead Form extensions active
- A Google Cloud project with the Google Ads API enabled
- A developer token (applied for in Google Ads → API Center)
Step 1 — Set Up OAuth in Google Cloud
1
Go to console.cloud.google.com → create or select a project.
2
Enable the Google Ads API under APIs & Services → Library.
3
Go to APIs & Services → Credentials → Create Credentials → OAuth Client ID.
4
Select Web Application and, under authorised redirect URIs, paste the OAuth redirect URI shown in Telemantix → Integrations → Google Ads.
5
Copy your Client ID and Client Secret.
Step 2 — Get a Developer Token
1
In your Google Ads account, go to Tools → API Center.
2
Apply for a developer token. For testing, the Test Account token works immediately.
3
For production, apply for Basic Access which requires approval.
Step 3 — Connect in Telemantix
1
Go to Integrations → Google Ads → Configure.
2
Enter your Client ID, Client Secret, and Developer Token.
3
Enter your Customer ID (10-digit Google Ads account ID, no dashes).
4
Click Connect with Google to authorize via OAuth.
Step 4 — Sync Leads
1
Save your account settings, click Test to verify account access, then Sync. The first pull starts with the previous day; later pulls resume the saved sync window.
2
Connected accounts with a Customer ID are scheduled every 15 minutes. Failed deliveries appear under Integrations → Delivery recovery.
3
For direct lead-form delivery, enter a private Google webhook key in Configure, save, and copy the callback URL into your Google Ads lead form. Use the same key in Google Ads and send its test webhook. Test submissions do not create CRM leads.

Common Issues
OAuth error: redirect_uri_mismatch
The redirect URI in Google Cloud Console must exactly match: the redirect URI shown in Telemantix (no trailing slash).
Developer token denied
Test tokens only work with Google Ads Test Accounts. Apply for Basic Access for production use.
No leads importing
Ensure your Google Ads campaign has Lead Form extensions (not just a landing page). Check that the Customer ID matches the account running the campaign.
