## Discussion

Discussion Each key is a metadata attribute name, such as name or campaignId, not a fixed field name. The entityMetaData field is a free-form map rather than an object with named properties, so the reference page labels this key Any Key. Both keys and values are strings, and the set of keys present varies by entityType. For example, a Campaign entity’s entityMetaData typically includes name. An AdGroup entity’s also includes the parent campaignId.
