Why Zernio vs Meta Business API?

Save 4-6 weeks of development time

Zernio API

  • Simple API key - start in 30 seconds

  • Automatic retries & queue management

  • Upload directly - we optimize for Meta

  • Zero maintenance forever

  • One API for 17 platforms

Meta Business API

  • 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

How It Works

Three steps to Facebook automation

1

Profile

default

Facebook

Connect your page

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

2

POST /v1/posts

const { data } = await zernio.posts.createPost({
  body: {
    content: 'Launch day! 🚀',
    mediaItems: [{ url: 'https://cdn.acme.com/launch.jpg' }],
    platforms: [
      { platform: 'facebook', accountId: 'acc_8f2a' },
    ],
    scheduledFor: '2027-01-15T14:30:00',
    timezone: 'Europe/Madrid',
  },
});

Build your integration

Use our simple REST API to schedule posts with text, images, videos, or links. Same pattern works for all 17 platforms.

We handle the rest

Zernio publishes at your scheduled time, retries on failures, and notifies you via webhooks. You never touch Meta's API directly.

Facebook API integration requires a Business page

Features

Everything you need to ship Facebook features

Messenger

Read and send Messenger DMs, with attachments, reactions, and delivery and read receipts.

Send an automatic DM when someone comments a keyword on a post.

Formats

Publish feed posts, multi-image posts, link carousels, Stories, and Reels to a Facebook Page.

Explore Meta Ads

Run paid ads on Facebook programmatically via the same API

Pages

Connect a Page and publish to it, with drafts, first comments, and country targeting on each post.

Reviews

Read the reviews on your Facebook Pages and reply to them.

Analytics

Pull impressions, likes, comments, shares, clicks, and views per post.

Integrate

Three ways in. Same API behind all of them

Write it yourself with the SDKs, hand it to an agent over MCP, or run it from a shell.

Read the docs
import Zernio from '@zernio/node';
const zernio = new Zernio(); // reads ZERNIO_API_KEY
const { data: post } = await zernio.posts.createPost({
body: {
content: 'Launch day! 🚀',
mediaItems: [{ type: 'image', url: 'https://cdn.acme.com/launch.jpg' }],
platforms: [
{
platform: 'facebook',
accountId: 'acc_xxx',
platformSpecificData: {
firstComment: 'Full changelog on our blog',
},
},
],
publishNow: true,
},
});
And more
