Social media automation has become a critical component of modern software systems, SaaS platforms, developer tools, and content workflows. Whether you're building a marketing platform, automation agent, developer tool, or personal automation system, managing social media programmatically across multiple platforms is challenging.

Each platform—Twitter/X, Instagram, LinkedIn, TikTok, YouTube, and others-has its own:

  • API structure
  • Authentication flow
  • SDK
  • Media requirements
  • Rate limits
  • Platform-specific behavior

Maintaining integrations with all of these platforms individually significantly increases engineering complexity, maintenance overhead, and development time.

Late solves this problem by providing a unified API and official SDK ecosystem that allows developers to automate publishing, scheduling, analytics, media uploads, and inbox management across 13 major social media platforms using a single integration.

Official Documentation:
https://docs.getlate.dev

Overview: What is Late?

Late is a developer-first social media automation and scheduling platform designed to unify social media integrations under one API.

Instead of building and maintaining separate integrations for each platform, Late provides:

  • One unified REST API
  • Official SDKs for multiple languages
  • Cross-platform publishing
  • Media upload and management
  • Analytics tracking
  • Scheduling and queue management
  • Unified inbox management

Core Architecture and Concepts

Understanding Late’s architecture helps in building scalable automation systems.

Profiles

Profiles act as containers for grouping accounts.

Example:

  • Personal profile
  • Company profile
  • Client profile

Each profile can contain multiple connected social accounts.

Accounts

Accounts represent actual connected social media accounts, such as:

  • Twitter account
  • LinkedIn page
  • Instagram profile
  • YouTube channel

Accounts belong to profiles.

Posts

Posts represent content that can be:

  • Published immediately
  • Scheduled for future publishing
  • Saved as drafts
  • Cross-posted to multiple platforms

Late automatically handles publishing to each platform.

Queue System

Late supports queue-based publishing, allowing automated scheduling using predefined time slots.

Example:

  • Monday 9 AM
  • Wednesday 2 PM
  • Friday 5 PM

Late automatically assigns posts to the next available slot.

Official SDK Support

Late provides official SDKs for multiple programming languages:

Language SDK
Node.js https://github.com/getlate-dev/late-node
Python https://github.com/getlate-dev/late-python
Go https://github.com/getlate-dev/late-go
Java https://github.com/getlate-dev/late-java
PHP https://github.com/getlate-dev/late-php
.NET https://github.com/getlate-dev/late-dotnet
Rust https://github.com/getlate-dev/late-rust
Ruby https://github.com/getlate-dev/late-ruby

These SDKs allow seamless integration into backend systems.

Node.js SDK Integration (Recommended)

Node.js SDK provides the most comprehensive integration capabilities.

Install:

npm install @getlate/sdk
Enter fullscreen mode Exit fullscreen mode

Example: Publish post

import { Late } from "@getlate/sdk";

const late = new Late({
  apiKey: process.env.LATE_API_KEY
});

await late.posts.create({
  content: "Automated post using Late Node.js SDK",
  platforms: [
    { platform: "twitter", accountId: "acc_xxx" },
    { platform: "linkedin", accountId: "acc_yyy" },
    { platform: "instagram", accountId: "acc_zzz" }
  ],
  publishNow: true
});
Enter fullscreen mode Exit fullscreen mode

Scheduling Posts 

await late.posts.create({
  content: "Scheduled post",
  scheduledFor: "2026-02-10T10:00:00Z",
  platforms: [
    { platform: "youtube", accountId: "acc_xxx" }
  ]
});
Enter fullscreen mode Exit fullscreen mode

Uploading Media 

const media = await late.media.upload("video.mp4");

await late.posts.create({
  content: "Video upload example",
  mediaUrls: [media.publicUrl],
  platforms: [
    { platform: "youtube", accountId: "acc_xxx" }
  ],
  publishNow: true
});
Enter fullscreen mode Exit fullscreen mode

Python SDK Integration

Install:

pip install late-sdk
Enter fullscreen mode Exit fullscreen mode

Example:

from late import Late

late = Late(api_key="YOUR_API_KEY")

late.posts.create(
    content="Automated Python post",
    platforms=[
        {"platform": "twitter", "accountId": "acc_xxx"}
    ],
    publish_now=True
)
Enter fullscreen mode Exit fullscreen mode

REST API Integration

Example:

curl -X POST https://getlate.dev/api/v1/posts \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
  "content": "Automated REST API post",
  "publishNow": true,
  "platforms": [
    {"platform": "linkedin", "accountId": "acc_xxx"}
  ]
}'
Enter fullscreen mode Exit fullscreen mode

This works with any language.

Cross-Platform Publishing

Example:

await late.posts.create({
  content: "Cross-platform automation example",
  publishNow: true,
  platforms: [
    { platform: "twitter", accountId: "acc_xxx" },
    { platform: "linkedin", accountId: "acc_yyy" },
    { platform: "facebook", accountId: "acc_zzz" },
    { platform: "instagram", accountId: "acc_aaa" }
  ]
});
Enter fullscreen mode Exit fullscreen mode

Analytics Integration 

const analytics = await late.analytics.get({
  period: "30d"
});

console.log(analytics);
Enter fullscreen mode Exit fullscreen mode
