WHY POSTZEN VS. META BUSINESS 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

Facebook native workflow

  • Complex OAuth with Facebook Business verification
  • Rate limit management with backoff logic
  • Media must meet strict Meta requirements
  • Constant updates when Graph API changes
  • Build separate integrations per platform

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

⚠️

Facebook Business Page Required

Facebook API integration requires a Business page. Personal profiles cannot use automated posting APIs due to Meta's restrictions.

You must be an admin of the page to connect it.

HOW IT WORKS

1.

Connect Your Page

Link your Facebook Business page through our dashboard. One-click OAuth - we handle all the Meta permissions.

2.

Build Your Integration

Use our simple REST API to schedule posts with text, images, videos, or links. Same pattern works for every supported platform.

3.

We Handle the Rest

PostZen publishes at your scheduled time, retries on failures, and shows publishing status for every post. You never touch Meta's API directly.

FEATURES

Ship Faster

Go from zero to posting in under 30 seconds. No Facebook app review, no Business Manager headaches - just get your API key and start building.

Official Flow, Zero Hassle

We use Meta's official Business 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.

CODE EXAMPLE

const response = await fetch('https://api.postzen.dev/v1/posts', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    platforms: [{
      platform: 'facebook',
      accountId: 'your-facebook-page-id'
    }],
    content: 'Exciting news! Check out our latest update 🚀',
    mediaItems: [{
      url: 'https://your-image-url.jpg'
    }],
    scheduledFor: '2024-01-15T14:00:00Z'
  })
});

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

FREQUENTLY ASKED QUESTIONS

Do I need a Facebook Business Page?
Yes. Facebook API integration requires a Facebook Business Page. You cannot post to personal profiles via API due to Meta's restrictions. You must be an admin of the page to connect it.
Why use PostZen instead of Meta's API directly?
Meta's Business API requires Facebook app verification, complex OAuth flows, media hosting, rate limit management, and ongoing maintenance. PostZen abstracts all of that - you get a simple API key and start posting in minutes.
Can I post to Facebook Groups via API?
Facebook restricts automated posting to Groups via third-party APIs. PostZen supports posting to Facebook Pages, which is the standard for business and brand automation.
Can I cross-post to Instagram from the same API call?
Yes. Include both 'facebook' and 'instagram' in your platforms array, or any other supported platforms. PostZen optimizes media and content for each platform automatically.
How much does the Facebook API cost?
Facebook's Graph API is free to use, but the integration costs weeks of engineering for Meta Business verification, OAuth, and ongoing version maintenance. PostZen is free up to 2 accounts and pay only for what you use beyond that.
