Metadata Tags

You can optionally set metadata tags in your product feed files. This enables Facebook to attribute catalogs using this feed to your app. Once a catalog is attributed to your app, the meta tag is not required in subsequent feed uploads to that catalog.

Include the following elements as space-delimited comments at the top of TSV/CSV feeds or inside a metadata tag in your XML feeds:

• ref_application_id — Your Facebook app ID
• ref_asset_id - ID that uniquely identifies this feed in your system
