Why Zernio vs Instagram Graph API?

Save 4-6 weeks of development time

Zernio API

  • 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 17 platforms with identical patterns

Instagram Graph API Direct

  • Complex OAuth 2.0 flow with Facebook Business verification

  • Strict rate limits requiring careful management and backoff logic

  • Media must be hosted on publicly accessible URLs before posting

  • Frequent API changes require constant code updates and testing

  • Separate integration needed for each social platform

How It Works

Three steps to Instagram automation

1

Profile

default

Instagram

Connect your account

Link your Instagram Business or Creator account through our dashboard. One-click OAuth - we handle all the Meta permissions.

2

POST /v1/posts

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

Build your integration

Use our simple REST API to schedule posts, stories, reels, or carousels. 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 Instagram's API directly.

Instagram integration works with Business and Creator accounts

Analytics

Pull impressions, reach, likes, comments, shares, saves, and views per post, plus per-Story insights.

Messaging

Read and send Instagram DMs, with attachments, reactions, and read receipts.

Webhooks

Get new comments, messages, and reactions delivered as they happen.

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: 'Behind the build 📸',
mediaItems: [{ type: 'image', url: 'https://cdn.acme.com/launch.jpg' }],
platforms: [
{
platform: 'instagram',
accountId: 'acc_xxx',
platformSpecificData: {
firstComment: 'Link in bio',
collaborators: ['partner_brand'],
},
},
],
publishNow: true,
},
});
And more
