Setup

Install the Skill from ClawHub

npx clawhub@latest install mikipalet/late-api

This downloads the skill and its rule files (authentication.md, posts.md, accounts.md, connect.md, platforms.md, webhooks.md, media.md) into your local skills directory.

Add Your API Key

Add your Late API key to your OpenClaw environment file:

echo 'LATE_API_KEY=sk_your_api_key_here' >> ~/.openclaw/.env

Replace sk_your_api_key_here with your actual key from getlate.dev/dashboard/api-keys.

Restart OpenClaw

Restart your OpenClaw session so it picks up the new skill:

openclaw restart

Using the Skill

Once installed, you can use natural language to manage your social media through OpenClaw:

Publishing Posts

You: Post "Just shipped a new feature!" to Twitter

OpenClaw: I'll post that to Twitter for you. Let me first check your connected accounts... Done! Posted successfully.

Scheduling

You: Schedule a LinkedIn post for tomorrow at 9am: "Excited to share our Q1 results"

OpenClaw: Scheduled your LinkedIn post for 2026-03-17 at 09:00 UTC.

Cross-Posting

You: Cross-post "Big announcement coming soon" to Twitter, LinkedIn, and Bluesky

OpenClaw: Posted to all three platforms successfully.

Managing Posts

You: Show me my recent posts

OpenClaw: Here are your recent posts: [lists posts with status, platform, and content]

You: Retry all my failed posts

OpenClaw: Found 2 failed posts. Retrying... Both posts published successfully.

Connecting Accounts

You: Connect my Instagram account

OpenClaw: I'll start the OAuth flow for Instagram. Open this URL to authorize: [auth URL]

Analytics

You: How did my last Twitter post perform?

OpenClaw: Your last tweet got 1,234 impressions, 56 likes, and 12 retweets.

Webhook Integration

OpenClaw can receive webhook events from external services to trigger Late API posts.

Configure an Incoming Webhook

Add a webhook endpoint to your OpenClaw configuration (~/.openclaw/openclaw.json):

{
  "webhooks": {
    "late-post": {
      "path": "/webhooks/late-post",
      "secret": "your_webhook_secret",
      "action": "Run the late-api skill to publish the post content from the payload"
    }
  }
}

External services can POST to http://your-openclaw-host:port/webhooks/late-post with a JSON body:

{
  "text": "Hello from a webhook!",
  "platform": "twitter"
}

OpenClaw will invoke the Late skill to publish the post.

Advanced Workflows

OpenClaw watches your blog RSS feed (via a scheduled skill or webhook)
When a new post is detected, it summarizes the content using AI
It crafts platform-appropriate versions (short for Twitter, longer for LinkedIn)
It calls Late API to post to each platform

Content Calendar

Store your content calendar in Apple Notes, Notion, or a local file
Set up a scheduled OpenClaw task to check for posts due today
OpenClaw reads the entry and posts via Late API

Media Uploads

You: Post this product photo to Instagram with the caption "New arrivals!"

OpenClaw: I'll generate a presigned upload URL for the image, upload it, and create the Instagram post.

The skill knows how to use presigned URLs for media uploads, handling the multi-step flow automatically.

Troubleshooting

"Skill not found"

Verify the skill is installed:

ls ~/.openclaw/skills/late-api/

You should see SKILL.md and the rule files. If not, reinstall:

npx clawhub@latest install mikipalet/late-api

"LATE_API_KEY not set"

Verify the environment variable is in your .env file:

grep LATE_API_KEY ~/.openclaw/.env

Make sure it starts with sk_ and has no extra spaces or quotes around the value.

Authentication Errors (401)

Check your API key at getlate.dev/dashboard/api-keys
Verify the key is active and not expired
Restart OpenClaw after any .env changes

Rate Limits (429)
