LinkedIn — how to connect

Posts to your personal profile and, optionally, Company Pages you administer. Personal posting uses THIS app (Sign In with LinkedIn + Share on LinkedIn). Company Pages need a SEPARATE LinkedIn app that has ONLY the Community Management API product — LinkedIn forbids that product alongside any other — connected as its own connection. Add your LinkedIn app's client ID and secret below, then connect with OAuth. Supports text, single image, video, and multi-image carousel (rendered as a PDF document).

LinkedIn needs TWO separate apps if you want both personal posting and Company Pages. LinkedIn forbids the Community Management API from sharing an app with any other product, so personal posting and Company-Page posting each live on their own app and connect as separate connections here. Set up the personal app first; add the company app when you're ready for Pages.

Before you start

A LinkedIn account, plus a Company Page you can associate the app with — LinkedIn requires an associated Page to create ANY app, even the personal one.
For Company Pages: an ADMINISTRATOR role on each Page you want to post to. LinkedIn only returns Pages where you are an admin.
For Company Pages: a SECOND LinkedIn app with the “Community Management API” product approved — it cannot be added to the personal app.

Step by step

1
Create the personal app
developer.linkedin.com → Create app. Associate it with a Company Page you control and verify the app.
Open
2
Add the personal products
Products tab → request “Sign In with LinkedIn using OpenID Connect” and “Share on LinkedIn”. Together these grant openid, profile, email and w_member_social — everything personal-profile posting needs.
3
Register the redirect URL
Auth tab → OAuth 2.0 settings → add the exact redirect URL this tool shows on the LinkedIn connect screen. It must match byte-for-byte (scheme, host, path, no trailing-slash mismatch).
4
Copy the personal app keys
Auth tab → copy the Client ID and Client Secret into this app’s LinkedIn settings (Client ID / Client secret), then Save.
5
Connect your personal profile
Channels → Connect → LinkedIn. You authorize as yourself and your personal profile is added as a channel.
6
Company Pages: create a SECOND app
Create a brand-new LinkedIn app and, on its Products tab, request ONLY the “Community Management API” product. LinkedIn rejects it if any other product is present or pending, so keep that app clean.
Open
7
Wait for Community Management API approval
That product needs LinkedIn’s review before its scopes work. Until it’s approved, connecting the company app fails with unauthorized_scope_error.
8
Wire the company app + turn on Company Pages
Add the SECOND app’s Client ID/Secret to its own LinkedIn connection, set “Company Page posting” to On in Settings, then connect it. The Pages you administer are offered in the channel picker — tick the ones you want.

App keys (set once in Settings)

Client ID
linkedin.com/developers → your app → Auth tab → "Client ID". Use the PERSONAL app here (products: Sign In with LinkedIn + Share on LinkedIn). Company-Page posting is a SEPARATE app + connection.
Client secretsecret
Same Auth tab → "Primary Client Secret". Register this tool's exact redirect URL under Auth → OAuth 2.0 settings, byte-for-byte.
API version
LinkedIn-Version header (YYYYMM). Blank = built-in default.
Company Page posting
Off by default. Company Pages need a SEPARATE LinkedIn app that has ONLY the Community Management API product (LinkedIn forbids it alongside Sign In + Share). Turn this on only on that dedicated app's connection — else connecting fails with unauthorized_scope_error.

Good to know

Requesting org scopes (w_organization_social, r_organization_admin) on an app WITHOUT the Community Management API approved makes the ENTIRE authorize fail with unauthorized_scope_error — that’s why “Company Page posting” is off by default.
Personal and Company connections are independent: you can hold both in one workspace, and the channel picker after connect lets you choose exactly which profile / Pages to add.
LinkedIn access tokens last ~60 days; the app refreshes them automatically once the app is approved for programmatic refresh.

Troubleshooting

unauthorized_scope_error on the LinkedIn login screen: The app is requesting a scope it isn’t approved for. For the company app, confirm the Community Management API product is APPROVED (not just requested). For the personal app, keep “Company Page posting” Off.
Connected, but no Company Pages appear in the picker: You connected the personal app (no org scopes) or you’re not an admin of the Page. Use the company app’s connection with “Company Page posting” On, and confirm your ADMIN role on the Page.
The authorize screen errors immediately / redirect_uri mismatch: The redirect URL registered on the app must exactly match the one this tool shows on the connect screen — copy it verbatim into the app’s OAuth 2.0 authorized redirect URLs.
Can’t add Community Management API to my existing app: LinkedIn requires it to be the ONLY product on an app. Create a NEW app dedicated to it — you cannot add it alongside Sign In / Share on LinkedIn.
