Late Node.js SDK

One API to post everywhere. 13 platforms, zero headaches.

The official Node.js SDK for the Late API — schedule and publish social media posts across Instagram, TikTok, YouTube, LinkedIn, X/Twitter, Facebook, Pinterest, Threads, Bluesky, Reddit, Snapchat, Telegram, and Google Business Profile with a single integration.

Installation

npm install @getlatedev/node

Quick Start

import Late from '@getlatedev/node';

const late = new Late(); // Uses LATE_API_KEY env var

// Publish to multiple platforms with one call
const { data: post } = await late.posts.createPost({
  body: {
    content: 'Hello world from Late!',
    platforms: [
      { platform: 'twitter', accountId: 'acc_xxx' },
      { platform: 'linkedin', accountId: 'acc_yyy' },
      { platform: 'instagram', accountId: 'acc_zzz' },
    ],
    publishNow: true,
  },
});

console.log(`Published to ${post.platforms.length} platforms!`);

Configuration

const late = new Late({
  apiKey: 'your-api-key', // Defaults to process.env['LATE_API_KEY']
  baseURL: 'https://getlate.dev/api',
  timeout: 60000,
});

Examples

Schedule a Post

const { data: post } = await late.posts.createPost({
  body: {
    content: 'This post will go live tomorrow at 10am',
    platforms: [{ platform: 'instagram', accountId: 'acc_xxx' }],
    scheduledFor: '2025-02-01T10:00:00Z',
  },
});

Platform-Specific Content

Customize content per platform while posting to all at once:

const { data: post } = await late.posts.createPost({
  body: {
    content: 'Default content',
    platforms: [
      {
        platform: 'twitter',
        accountId: 'acc_twitter',
        platformSpecificContent: 'Short & punchy for X',
      },
      {
        platform: 'linkedin',
        accountId: 'acc_linkedin',
        platformSpecificContent: 'Professional tone for LinkedIn with more detail.',
      },
    ],
    publishNow: true,
  },
});

Upload Media

// 1. Get presigned upload URL
const { data: presign } = await late.media.getMediaPresignedUrl({
  body: { filename: 'video.mp4', contentType: 'video/mp4' },
});

// 2. Upload your file
await fetch(presign.uploadUrl, {
  method: 'PUT',
  body: videoBuffer,
  headers: { 'Content-Type': 'video/mp4' },
});

// 3. Create post with media
const { data: post } = await late.posts.createPost({
  body: {
    content: 'Check out this video!',
    mediaUrls: [presign.publicUrl],
    platforms: [
      { platform: 'tiktok', accountId: 'acc_xxx' },
      { platform: 'youtube', accountId: 'acc_yyy', youtubeTitle: 'My Video' },
    ],
    publishNow: true,
  },
});

Get Analytics

const { data } = await late.analytics.getAnalytics({
  query: { postId: 'post_xxx' },
});

console.log('Views:', data.analytics.views);
console.log('Likes:', data.analytics.likes);
console.log('Engagement Rate:', data.analytics.engagementRate);

List Connected Accounts

const { data } = await late.accounts.listAccounts();

for (const account of data.accounts) {
  console.log(`${account.platform}: @${account.username}`);
}

Error Handling

import Late, { LateApiError, RateLimitError, ValidationError } from '@getlatedev/node';

try {
  await late.posts.createPost({ body: { /* ... */ } });
} catch (error) {
  if (error instanceof RateLimitError) {
    console.log(`Rate limited. Retry in ${error.getSecondsUntilReset()}s`);
  } else if (error instanceof ValidationError) {
    console.log('Invalid request:', error.fields);
  } else if (error instanceof LateApiError) {
    console.log(`Error ${error.statusCode}: ${error.message}`);
  }
}
