Get Audience Count - Markifact

Size a LinkedIn audience from targeting criteria before building anything. Use it to check a targeting spec clears LinkedIn’s 300 member minimum, and to compare how much each facet narrows the audience. Look up real facet URNs with linkedin_ads_search_targeting first.

Inputs

Field	Type	Required	Default	Description
`targeting_criteria`	object or string	Yes	-	LinkedIn targetingCriteria object describing the audience, as a dict or JSON string, for example {‘include’: {‘and’: [{‘or’: {‘urn:li:adTargetingFacet:locations’: [‘urn:li:geo:103644278’]}}]}}. Use linkedin_ads_search_targeting to look up real URNs and do not invent them. LinkedIn requires locations, and in practice also interfaceLocales, before it will answer.

Output
