Overview

Create a post on a company page. The authenticated account must be an admin of the specified company page.

This endpoint consumes 1 credit per request. Ignore this if you’re on per-seat pricing: usage is unlimited.

You must be an admin of the company page to create posts on its behalf.

Request

string

required

Your API key for authentication.

string

required

The unique identifier of the account to use.

string

required

Must be "create_company".

object

required

Show params properties

string

required

The URL of the company page on the connected platform (e.g. "https://www.linkedin.com/company/acme-corp").

string

The text content of the post. Supports hashtags (#tag), line breaks and people mentions. To mention someone, use mention_user(public_id, display_text) where public_id is the slug of their profile URL (linkedin.com/in/<public_id>) and display_text is the clickable text shown in the post — e.g. "Great talk mention_user(williamhgates, Bill Gates)!". To mention a company page, use mention_company(slug, display_text) where slug is from linkedin.com/company/<slug> — e.g. "Proud to partner with mention_company(microsoft, Microsoft)".

string | object

A single file to attach — an image (.jpg, .png, .gif, .webp), a video (.mp4, .mov, .webm…) or a document (.pdf, .doc, .docx, .ppt, .pptx), which LinkedIn publishes as a page carousel. Can be a URL string or an object with filename and data properties.

Show file object properties

string

The name of the file including extension (e.g. "photo.jpg").

string

Base64-encoded file data.

string | object

Custom cover image for a video post. Only valid when file is a single video (.mp4, .mov, .webm…). Same format as file: a URL string or an object with filename and data (base64). Without it, LinkedIn picks a frame of the video.

array

An array of files for carousel posts. Each element can be a URL string or an object with filename, data, and optional altText properties.

Show file object properties

string

The name of the file including extension.

string

Response

boolean

Unique identifier of the post. Treat it as an opaque string and pass it back exactly as returned.

object

string

The action that was performed ("create_company").

string

The account ID used for the request.

integer
