Inputs

Field	Type	Required	Default	Description
`author`	string or SelectItem	Yes	-	Who publishes the post: ‘me’ for the connected member’s personal profile, or a Company Page id from linkedin_select_pages (urn:li:organization:<id> also works). There is no default: confirm with the user which one they mean.
`text`	string	No	-	The post text. Hashtags (#marketing) work as typed. Mention a page or member with @[Exact Name](urn:li:organization:<id>) or @[Name](urn:li:person:<id>); the name must match the entity’s LinkedIn name or it shows as plain text.
`link_url`	string	No	-	Share a link as an article card. LinkedIn does not scrape the page, so set link_title (and optionally link_description and link_thumbnail_url) to control how the card looks.
`link_title`	string	No	-	Article card title.
`link_description`	string	No	-	Article card description.
`link_thumbnail_url`	string	No	-	Article card image. Accepts direct URLs, Google Drive share links with sharing set to ‘Anyone with the link’, or files uploaded through Markifact.
`image_urls`	string or array of string	No	-	One image, or 2 to 20 images for a multi-image post (JPG, PNG or GIF). Accepts direct URLs, Google Drive share links with sharing set to ‘Anyone with the link’, or files uploaded through Markifact.
