LinkedIn Company Tagging

Tag other LinkedIn company pages directly from the posterly composer. Tagged companies get a notification and the mention shows up as a clickable blue link in your published post — exactly like when a human types @companyname in LinkedIn's own composer.

Adding a tag

1. Open the composer and select a LinkedIn account
2. Click the @ icon in the caption toolbar to open Tag a LinkedIn company
3. Paste the company's LinkedIn URL and click Add company
4. If the company isn't already in posterly's cache, type the company name exactly as it appears on LinkedIn (case, spacing, punctuation all have to match)
5. Click Insert on the company chip to drop the tag into your caption
6. When you publish, posterly replaces the placeholder with a live LinkedIn mention

Finding the right URL

LinkedIn's mention API needs the company's numeric ID, not its vanity name. The URL you need looks like this:

https://www.linkedin.com/company/18904665/

Not like this:

https://www.linkedin.com/company/grassroots-creative-agency/   ← vanity URL, won't always work

Method 1: Numeric URL (easiest)

If you're an admin of the company page, LinkedIn often shows you the numeric URL directly in the admin view. Copy that one.

Method 2: "See all employees" trick (works for any company)

Most public pages use vanity URLs, so here's a one-click way to get the numeric ID:

1. Go to the company's LinkedIn page
2. Find the See all employees link (usually right under the follow button, above the company description)
3. Click it
4. Copy the URL from your browser — it'll look like this:

   https://www.linkedin.com/search/results/people/?currentCompany=%5B%2218904665%22%5D
   

5. Paste that URL into posterly — we pull the numeric ID out automatically

The number inside currentCompany=["..."] is the company's LinkedIn ID.

Why the name has to match exactly

LinkedIn's Posts API silently strips any mention whose display name doesn't exactly match the company's canonical LinkedIn name — case, spacing, and punctuation all matter. If you type "Grassroots Creative" but LinkedIn stores "Grassroots Creative Agency", the mention will render as plain black text, no link, no notification.

posterly auto-fetches the canonical name when:

• You're an admin of the company (LinkedIn returns its name via API)
• Or the company has already been resolved by any other posterly user — we cache canonical names across workspaces, so over time most companies just work

If neither applies and posterly asks you to type the name, copy it character-for-character from the top of the company's LinkedIn page.

Recently tagged

The popover remembers the last eight companies tagged in your workspace. Click any of them to re-tag without pasting URLs again.

Limitations

• Companies only. LinkedIn's public API doesn't let third-party apps tag individual people (/in/username). This is a LinkedIn restriction, not a posterly one.
• No self-tagging. LinkedIn strips mentions where the author equals the mentioned entity — you can't tag your own company page.
• Exact name match required. LinkedIn renders non-matching names as plain text (see above).
• One-to-one URL → company. If a company has rebranded and kept a different vanity URL, use the numeric URL to be safe.

What the tag looks like

In the posterly composer your tag appears as @[Company Name]. In the published LinkedIn post it becomes a blue clickable link, and LinkedIn notifies the tagged company.
