Why Zernio vs LinkedIn Marketing API?

Save 4-6 weeks of development time

Zernio API

  • Simple API key - start in 30 seconds

  • Automatic retries & queue management

  • Upload directly - we handle LinkedIn's format

  • Zero maintenance forever

  • One API for 17 platforms

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

How It Works

Three steps to LinkedIn automation

1

Profile

default

LinkedIn

Connect your account

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

2

POST /v1/posts

const { data } = await zernio.posts.createPost({
  body: {
    content: 'We just shipped v2',
    mediaItems: [{ url: 'https://cdn.acme.com/launch.jpg' }],
    platforms: [
      { platform: 'linkedin', 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 documents. 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 LinkedIn's API directly.

Post to your personal LinkedIn profile or any company page you admin

Features

Everything you need to ship LinkedIn features

Personal profiles

Publish to a LinkedIn member's own profile, with analytics and comments on the same connection.

Company pages

One connected account can publish to any organization page that member administers.

Posts

Publish text, image, video, document, and polls, and edit the text of anything already published.

Explore LinkedIn Ads

Run paid ads on LinkedIn programmatically via the same API

Zernio's LinkedIn Ads API lets you run and manage campaigns - no LinkedIn developer approval required.

Analytics

Pull impressions, reach, likes, comments, and shares for your LinkedIn posts, plus follower and page-view stats for company pages.

First comment

Drop your link in an automatic first comment.

Mentions

Turn a company or profile URL into an @mention you can embed in your post text.

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: 'We just shipped v2',
mediaItems: [{ type: 'image', url: 'https://cdn.acme.com/launch.jpg' }],
platforms: [
{
platform: 'linkedin',
accountId: 'acc_xxx',
platformSpecificData: {
firstComment: 'Full changelog in the comments',
disableLinkPreview: true,
},
},
],
publishNow: true,
},
});
