Ad Delivery Checks

Delivery checks are a set of tests which can help find out potential issues related to ad delivery.

Run And Read

To run the ad delivery checks and get the failed check results, read the failed_delivery_checks field of an ad. For example, running delivery checks for ad 6014290603725:

curl -G \
  -d 'fields=failed_delivery_checks' \
  -d 'access_token=<ACCESS_TOKEN>' \
  https://graph.facebook.com/v19.0/<AD_ID>

If all the checks have passed failed_delivery_checks field will not be part of the response.

For example, the response for an ad with a failed invalid_custom_audiences check will be in a form of:

{
 "failed_delivery_checks": [\
    {\
      "summary": "Custom Audience No Longer Shared",\
      "description": "This ad uses a custom audience that's no longer being shared with you. Please contact the person who set up the audience for more information.",\
      "check_name": "invalid_custom_audiences",\
    }\
  ],
  "id": "6014290603725"
}

The failed_delivery_checks field is a JSON array which contains JSON objects of the failed checks. Each failed check has the following fields:

Name	Description	Type
check_name	The name of the failed check (See Delivery Check types)	String
summary	One line description of the error	String
