Requires App Review.The leads_retrieval permission allows your app to retrieve and read all information captured by a lead ads form associated with an ad created in Ads Manager or the Marketing API. The allowed usage for this permission is to contact people who completed your lead ad form requesting more information. For example, an auto dealer reaching out to a potential customer (lead) that responded to their ad with quotes for a car. This permission can also be used by advertiser authorized CRM platforms to pull the lead data on behalf of the advertisers. These advertisers can then use the lead information to reach out to the user. Note: Requires the manage_pages permission to work correctly. You may also use this permission to request analytics insights to improve your app and for marketing or advertising purposes, through the use of aggregated and de-identified or anonymized information (provided such data cannot be re-identified).
