Overview

Complete guide to all social media platforms supported by Zernio API

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:

typescript

const { url } = await zernio.connect.getConnectUrl({
  path: { platform: 'twitter' },
  query: { profileId: 'YOUR_PROFILE_ID' },
});
// Redirect the user to `url` to start the OAuth flow.

python

res = client.connect.get_connect_url(
    platform="twitter",
    profile_id="YOUR_PROFILE_ID",
)
# Redirect the user to res["url"] to start the OAuth flow.

bash

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:

typescript

const post = await zernio.posts.createPost({
  body: {
    content: 'Hello from Zernio API!',
    platforms: [
      { platform: 'twitter', accountId: 'YOUR_ACCOUNT_ID' },
    ],
    publishNow: true,
  },
});

python

post = client.posts.create_post(
    content="Hello from Zernio API!",
    platforms=[
        {"platform": "twitter", "accountId": "YOUR_ACCOUNT_ID"},
    ],
    publish_now=True,
)

bash

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:

typescript

const post = await zernio.posts.createPost({
  body: {
    content: 'Cross-posting to all platforms!',
    platforms: [
      { platform: 'twitter', accountId: 'acc_twitter' },
      { platform: 'linkedin', accountId: 'acc_linkedin' },
      { platform: 'bluesky', accountId: 'acc_bluesky' },
    ],
    publishNow: true,
  },
});

python

post = client.posts.create_post(
    content="Cross-posting to all platforms!",
    platforms=[
        {"platform": "twitter", "accountId": "acc_twitter"},
        {"platform": "linkedin", "accountId": "acc_linkedin"},
        {"platform": "bluesky", "accountId": "acc_bluesky"},
    ],
    publish_now=True,
)

bash

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"}
    ],
    "publishNow": true
  }'
