Posts to a profile or Company Page. Add media, an article card, or @mention an organization.

LinkedIn's official API is powerful — and painful

Posting through the LinkedIn Posts API means Marketing Developer Platform access, OAuth, and an author URN that is either a urn:li:person or a urn:li:organization. Media must be registered and uploaded before you can reference it, and link-card thumbnails must be uploaded as assets — LinkedIn rejects raw URLs. Outstand turns all of it into a single request.

Marketing Developer Platform access and app review
Connect once via OAuth — we manage the app and permissions, or bring your own
Author URNs differ for a person vs an organization
We resolve the right person/organization URN for each account
Media needs registerUpload → upload → reference the asset URN
Pass a media URL; we register, upload and reference the asset
Article cards reject raw URLs — thumbnails must be uploaded assets
Send a thumbnailUrl; we upload it and attach the image URN
Mentions need the exact registered name in annotation format
Give us { urn, text }; we rewrite the inline mention correctly
60-day tokens that expire silently
Automatic token refresh — you never see a 401

LinkedIn API FAQ

The questions developers ask before they build.

Does LinkedIn have an official API?

Yes — the LinkedIn Posts API (part of the Marketing Developer Platform) lets approved apps publish posts, share articles and read analytics for member profiles and Company Pages. Outstand is a managed layer on top of it, so you skip the setup.

Can I post to a Company Page and a personal profile via API?

Yes. Both work through the same POST /v1/posts/ call — Outstand resolves the correct author URN (urn:li:organization for a Page, urn:li:person for a profile) based on the connected account.

Can I share an article or link with a custom card?

Yes. Pass linkedin.article with a source URL plus optional title, description and thumbnailUrl. Outstand uploads the thumbnail to LinkedIn and attaches the image URN, since LinkedIn rejects raw URLs as thumbnails.

Can I @mention a company on LinkedIn via API?

Yes. Pass linkedin.mentions with the entity URN and its exact, case-sensitive registered name. The matching text in your post is rewritten into LinkedIn’s annotation format so it renders as a clickable mention.

Can I schedule LinkedIn posts via the API?

Yes. Add a scheduledAt ISO-8601 timestamp (up to 30 days ahead) and Outstand publishes the post automatically — no cron or queue on your side.

Can I read and reply to LinkedIn comments via the API?

Yes. Read the comments on a published post with GET /v1/posts/{id}/replies?network=linkedin and post a reply with POST /v1/posts/{id}/replies.

Can I delete a LinkedIn post via the API?

Yes. LinkedIn supports deleting posts via the API, and Outstand exposes it through DELETE /v1/posts/{id}/remote.
