Facebook Ads
Facebook Ads connections give you access to your company’s Facebook ads statistics data.
Source Setup
We use OAuth to authenticate with Facebook. The connection setup page will forward you to Facebook to authenticate and authorize Etleap to extract ads data from your Facebook account.
For Lead Ads, Etleap will extract leads data for ads belonging to pages the user has given permission to. If you want to extract leads data for all pages, make sure to give access for leads retrieval to all current and future pages.
