WHY POSTZEN?

PostZen vs. Meta Business API

Meta Business API brings its own authentication, rate limits, media rules, and maintenance. PostZen replaces it with one predictable integration.

CODE EXAMPLE

Create a Post on Facebook via API

One POST request to /v1/post — send a file or a public URL

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

Still have 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.
