minipostiz-cli — LinkedIn Setup

End-to-end guide to get a working LinkedIn access token and store it in minipostiz-cli. Covers app creation, product activation, OAuth flow, and credential storage.

What you need

Credential	Source
accessToken	OAuth 2.0 flow (60-day TTL)
personUrn	auto-resolved from token via /v2/userinfo if openid scope included

---

Step 1 — LinkedIn Developer App

1. Go to https://www.linkedin.com/developers/apps → Create app
2. Fill in app name, company page, logo → submit
3. In the app → Products tab → request both:
   • Share on LinkedIn → grants w_member_social (posting)
   • Sign In with LinkedIn using OpenID Connect → grants openid profile email (personUrn resolution)
4. In Auth tab → add redirect URI: http://localhost:3001
5. Note your Client ID and Client Secret

Both products are usually auto-approved for developer apps within seconds.

Step 2 — Run the OAuth server

Create and run /tmp/linkedin-oauth-minipostiz.js:

#!/usr/bin/env node
const http = require('http');
const url = require('url');
const crypto = require('crypto');

const CLIENT_ID = 'YOUR_CLIENT_ID';
const CLIENT_SECRET = 'YOUR_CLIENT_SECRET';
const REDIRECT_URI = 'http://localhost:3001';
const SCOPE = 'w_member_social openid profile email';
const STATE = crypto.randomBytes(16).toString('hex');

const authUrl = `https://www.linkedin.com/oauth/v2/authorization?` +
  new URLSearchParams({ response_type: 'code', client_id: CLIENT_ID,
    redirect_uri: REDIRECT_URI, state: STATE, scope: SCOPE }).toString();

console.log('\n=== LinkedIn OAuth for minipostiz-cli ===');
console.log('\nOpen this URL in your browser:\n');
.(authUrl);
.();

 server = http.( (req, res) => {
   { pathname, query } = url.(req., );
   (pathname !== ) { res.(); res.(); ; }

   { code, state, error } = query;
   (error) { .(, error); res.(); server.(); ; }
   (state !== ) { .(); res.(); server.(); ; }

  
   tokenRes =  (, {
    : ,
    : { :  },
    :  ({ : , code,
      : , : , :  }).()
  });
   token =  tokenRes.();

   (!token.) {
    .(, .(token));
    res.();
    server.(); ;
  }

  .();
  .(, token.);
  .(, token., );

  
   uiRes =  (, {
    : { :  }
  });
   ui =  uiRes.();
   personUrn = ui. ?  : ;

   (personUrn) {
    .(, personUrn);
    .(, ui.);
  }

  
   fs = ();
  fs.(, token.);
   (personUrn) fs.(, personUrn);

  .();
  .();
  .();
  .();

  res.(, { :  });
  res.();
  server.();
});

server.();
process.(,  { server.(); process.(); });

Run it:

node /tmp/linkedin-oauth-minipostiz.js

---

Step 3 — Store credentials in minipostiz-cli

The script prints the exact command. Run it:

# Direct binary
minipostiz auth --platform linkedin \
  --accessToken "$(cat /tmp/linkedin-access-token.txt)" \
  --personUrn "$(cat /tmp/linkedin-person-urn.txt)"

# Or via supercli
sc minipostiz auth set-linkedin \
  --accessToken "$(cat /tmp/linkedin-access-token.txt)"
# (personUrn auto-resolved at post time if openid scope was included)

---

Step 4 — Verify and test

# Verify credentials are valid
minipostiz auth verify --platform linkedin

# Fire a test post
minipostiz publish --platform linkedin --message "LinkedIn API test via minipostiz-cli"

# Check history
minipostiz history --platform linkedin --limit 5

---

Step 5 — Cleanup

rm /tmp/linkedin-oauth-minipostiz.js /tmp/linkedin-access-token.txt /tmp/linkedin-person-urn.txt

---

Troubleshooting

Error	Cause	Fix
invalid_scope	App missing required product	Add "Share on LinkedIn" + "Sign In with OpenID" in Products tab
redirect_uri_mismatch	URI not registered	Add http://localhost:3001 in Auth tab → OAuth 2.0 settings
403 ugcPosts.CREATE	Token missing w_member_social	Re-run OAuth — scope must include w_member_social
Token Type: undefined	Exchange response parsing bug	Use the Node.js script above — captures full response
personUrn not resolved	Token has no openid scope	Re-run with openid profile email included in scope

Token lifetime

• Expires in 60 days (5,184,000 seconds)
• No refresh token in standard OAuth — re-run the flow before expiry
• Re-run: node /tmp/linkedin-oauth-minipostiz.js → paste new token via minipostiz auth --platform linkedin ...
