How can I start using Facebook Ads Remarketing?
Meta targets its users using their email addresses or phone numbers via an external data source. Therefore, you need to provide your users' email addresses or phone numbers, along with their GDPR opt-in status, to Insider One before starting to use Meta Custom Audiences. You can pass this data using the Upsert User API, Insider Object Integration, Web SDK or App SDK Integration.
- Go to Insider One's InOne panel and click on your user name to navigate to Inone Settings > Integration Settings > Facebook Ads Integration.

- Click the Continue with Facebook button to authenticate with your Facebook Business Manager account. Once authenticated, the integration will require permission to access any Facebook Ad account linked to your Facebook Business Manager account.

- You will see a table below the connection button. Add your Ad account user to the table.

- You will see that your connected account resides under the table below.

Send a segment from Insider One to Facebook Ads
You can start sending the segments you want to Facebook Ads through the corresponding icons on the Dynamic Segments listing page.
- Administrator
- Editor
- Collaborator
Additionally, the user intending to send the segments to the Ads channels must have admin access in their corresponding Ads account profile.

The modal opens when you click the button to send the segment to Facebook to sync the audience. You need to select the Facebook Ads account, enable the Start sending toggle to validate sending, and then click the Save button.
Once the segment is sent from Insider One, you can view the audiences that Insider One sent, which have an “insider” prefix.
You will create a custom audience list that includes many people from your database.
When you try to use this custom audience list to target your ads, Facebook can only match a small percentage of the people on the list.
- This is because Facebook will not be able to match the phone numbers in your database to those in its database.
Accept the Facebook Custom Audience Terms
The Facebook Custom Audience Terms should be accepted to send the segment to the Facebook Ads side. If you click on the underlined title in the error toaster, you will be redirected to the manager page of the respective connected ads account.
You can accept the terms on the Facebook Ads account’s manager page and proceed to try to send your segment again to Facebook.
