Overview

Zernio supports 15 major social media platforms. Each platform page includes quick start examples, media requirements, and platform-specific features.

Platform Quick Reference

Getting Started

1. Connect an Account

Each platform uses OAuth or platform-specific authentication. Start by connecting an account:

curl "https://zernio.com/api/v1/connect/{platform}?profileId=YOUR_PROFILE_ID" \
  -H "Authorization: Bearer YOUR_API_KEY"

Replace {platform} with: twitter, instagram, facebook, linkedin, tiktok, youtube, pinterest, reddit, bluesky, threads, googlebusiness, telegram, snapchat, whatsapp, or discord.

2. Create a Post

Once connected, create posts targeting specific platforms:

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Hello from Zernio API!",
    "platforms": [
      {"platform": "twitter", "accountId": "YOUR_ACCOUNT_ID"}
    ],
    "publishNow": true
  }'

3. Cross-Post to Multiple Platforms

Post to multiple platforms simultaneously:

curl -X POST https://zernio.com/api/v1/posts \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Cross-posting to all platforms!",
    "platforms": [
      {"platform": "twitter", "accountId": "acc_twitter"},
      {"platform": "linkedin", "accountId": "acc_linkedin"},
      {"platform": "bluesky", "accountId": "acc_bluesky"}
    ],

Analytics KPIs Matrix

Which metrics does the Analytics API return for each platform?

* LinkedIn views only for video posts

** YouTube shares only available via daily Analytics API, not basic Data API

YouTube also supports audience demographics (age, gender, country breakdowns) via a dedicated endpoint.

Google Business also supports daily performance metrics (impressions, clicks, calls, directions, bookings) and search keywords via dedicated endpoints.

Inbox Feature Matrix

Requires Inbox add-on — Build: +$10/mo · Accelerate: +$50/unit · Unlimited: +$1,000/mo

The Inbox API provides a unified interface for managing DMs, comments, and reviews across all platforms.

DMs Support

Comments Support

Reviews Support

Webhooks

Base message + comment events:

Message lifecycle events (edits, unsends, delivery status):

Dashes indicate the underlying platform API does not expose that event; the gap is a platform limitation, not a Zernio one.
