Meta Ads

API keyAdvertisingOrg connection

Org-level connection

Meta Ads is connected once at the org level by an admin. The credential is shared across all groups that have been granted access — individual team members don't need to connect their own accounts.

Getting your API key

In Meta Business Suite, go to Business Settings → Users → System Users

Create a System User (Admin role), then click "Generate New Token"

Select your app, set token expiration to "Never", and add permissions: ads_read, ads_management, business_management

Copy the System User access token and paste it below

Note: Your Meta app must have Standard Access (not Development) for production use. Apply via the app's App Review page.

Ready to connect?

Sign in to On Belay and open the Integrations page to add Meta Ads.

Permissions (scopes)

These are the data scopes On Belay can be granted for Meta Ads. Your org admin controls which scopes are enabled per group.

Troubleshooting

"Invalid API key" or "Unauthorized" error
Double-check that you copied the full key without any leading/trailing spaces. Some platforms show a truncated preview — make sure to copy the full token. If the key was generated with restricted scopes, verify it includes the permissions listed above.
Connected but Claude can't access data
Check that your group has been granted access to this integration in On Belay → Groups → [your group] → Integrations. Also verify the specific scopes your group is permitted to use match what your query requires.
The key expires or stops working
Some API keys have expiration policies. Generate a new key in Meta Ads and update it in On Belay → Integrations → Meta Ads → Update key. Consider creating a dedicated service account or machine user for On Belay so the key isn't tied to a personal account.
