Update Post

Low-level LinkedIn post update

Low-level LinkedIn post update. Forwards a raw Posts API partial-update body as-is. This is how an ad’s editable content is changed: resolve the ad’s post URN via linkedin_ads_get_ad, then patch commentary (intro text), contentLandingPage (destination URL), contentCallToActionLabel, or adContext.dscName/dscStatus. Headline and attached media are never editable (LinkedIn limitation; create a new ad instead). Requires the connected user to have an admin or DSC-poster role on the authoring Company Page.

Inputs

Field	Type	Required	Default	Description
post	string or SelectItem	Yes	-	The post to update, as a full URN (urn:li:ugcPost:123 or urn:li:share:123). An ad’s content lives on its referenced post: get the URN from linkedin_ads_get_ad (creative.content.reference).
update_payload	object or string	Yes	-	Raw LinkedIn post partial-update body, sent to LinkedIn as-is. Use LinkedIn’s documented shape: {“patch”: {“set": \{...}}}. LinkedIn only allows updating: commentary (intro text), contentLandingPage (destination URL), contentCallToActionLabel, lifecycleState, and the sponsored name/status via a nested patch: \{"patch": \{"adContext": \{"set”: {“dscName”: ”…”}}}}. Headline and attached media cannot be updated (LinkedIn limitation; create a new ad instead). Accepts a JSON object or JSON string.
dry_run	boolean	No	False	When true, return the resolved update body without calling LinkedIn.

SelectItem

Field	Type	Required	Default	Description
value	string	Yes	-	The value of the selectable item.
label	string	Yes	-	The label of the selectable item, used for display purposes. If not provided, defaults to the value.
