WHY POSTZEN VS. LINKEDIN MARKETING API?

PostZen

  • Simple API key authentication - no OAuth complexity
  • We handle rate limits automatically with smart queuing and retries
  • Upload media directly to us - we host and optimize it for you
  • Zero maintenance - we handle all API changes behind the scenes
  • One integration for 10 social platforms with identical patterns

LinkedIn Marketing API

  • Complex OAuth with LinkedIn partner program approval
  • Strict rate limits with daily quota management
  • Media must be uploaded in multiple steps
  • Frequent API changes require constant updates
  • Build separate integrations per platform

Save 4-6 weeks of development time. Ship your LinkedIn API integration today, not next month.

HOW IT WORKS

1.

Connect Your Account

Link your LinkedIn profile or company page through our dashboard. One-click OAuth - we handle all the LinkedIn permissions.

2.

Build Your Integration

Use our simple REST API to schedule text, up to 20 images, a video, or a PDF carousel. Same pattern works for every supported platform.

3.

We Handle the Rest

PostZen publishes at your scheduled time and retries on failures. You never touch LinkedIn's API directly.

FEATURES

Ship Faster

Go from zero to posting in under 30 seconds. No LinkedIn partner program approval - just get your API key and start building.

Official API, Zero Hassle

We use LinkedIn's official Marketing API under the hood. You get full compliance and reliability without the integration pain.

We Handle the Hard Parts

Rate limits, token refresh, media processing, error handling - all managed for you. Focus on your product, not infrastructure.

      accountId: 'your-linkedin-account-id'
    }],
    content: 'Publishing LinkedIn thought leadership content via PostZen!',
    mediaItems: [{
      url: 'https://your-image-url.jpg'
    }],
    scheduledFor: '2024-01-15T14:00:00Z'
  })
});

const result = await response.json();
console.log('LinkedIn scheduled:', result.post._id);

FREQUENTLY ASKED QUESTIONS

Do I need LinkedIn Partner Program approval?
Not with PostZen. We handle all LinkedIn platform partnerships and approvals on your behalf. You get a simple API key and start posting immediately.
Can I post to both personal profiles and company pages?
Yes. Connect personal LinkedIn profiles or any Company Page you admin. Both work through the same API endpoint - add the page URN to the request and PostZen publishes as the page. Company pages also unlock country targeting and longer videos.
Does the LinkedIn API support document posts?
Yes. PostZen publishes LinkedIn document posts - the swipeable PDF carousels - alongside text, up to 20 images per post, video, quote reshares, and link posts. Add an optional first comment to any of them.
Does PostZen support LinkedIn analytics?
No. The Analytics API is currently under development.
How much does the LinkedIn API cost?
LinkedIn's Marketing API is free after Partner Program approval, but integration typically requires 4-8 weeks of engineering. PostZen is free up to 2 accounts and pay only for what you use beyond that.
