These errors can occur from a variety of root causes. Even if you’re not sure of the root cause, the steps below can solve a variety of issues. 

Troubleshooting steps

Review your Meta account and settings

First, confirm you have complete control of your Meta Business Account, Facebook page, and Advertising account.

1. Visit your Meta Business settings. 
2. At the link, click your user name under People.
3. If you are using Lead Ads: make sure the Facebook page you wish to connect to Klaviyo has Full control permissions. If it does not, click Manage and adjust the permissions. Once you have full control, you can continue.
   
4. If you are using Custom Audiences: make sure the Ad account you wish to connect to Klaviyo has Full control permissions. If it does not, click Manage and adjust the permissions. Once you have full control, you can continue.

Accept Meta’s terms of service

To accept Meta's terms of service:

1. Copy and paste the following URL into your browser, but do not hit enter:

    https://business.facebook.com/ads/manage/customaudiences/tos/?act=AdAccountID

   
2. You'll need to update the link above by changing AdAccountID to your specific ad account ID from Meta. To find this ID:
1. Open a new tab and navigate to Ad accounts in Meta’s business settings.
2. Select your ad account on the left.
3. Find the account ID, under the account name on the right.
   
4. Copy the ID.
3. In your original tab, replace AdAccountID with the ID you copied from Meta, then hit enter.
   
4. Review and accept the terms of service.

Re-authenticate Klaviyo and Meta Ads

1. In Klaviyo, select the Integrations tab.
2. Find Meta Ads on the list and select it.
3. On your settings page, click Manage integration > Re-authenticate in the upper right corner.
   

Your integration should now start syncing normally.
