# 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
