Post to LinkedIn from Claude

How it works

1. Claude calls list_channels to find your LinkedIn channel.
2. It calls get_channel_rules to learn the LinkedIn limit, media needs and settings.
3. It writes the post and runs check_post, which returns any rule problems.
4. It picks a time with find_free_slot if you did not give one, shows you the post, and calls schedule_post after you say yes.

LinkedIn rules Claude follows

• Up to 3,000 characters. Up to 9 images or 1 video, never both.
• Turn on the carousel setting to show several images as a set.
• Follow-up comments are posted as comments. Company Pages can also auto repost and auto plug.
• Postozo escapes special characters so LinkedIn does not cut the post short.

Rule summary from the LinkedIn connector: Max 3000 characters. Up to 9 images or 1 video. Follow-up comments are posted as comments.

LinkedIn settings the agent can use

These go in channels[].settings of schedule_post. Claude learns them from get_channel_rules, so you can just describe what you want.

LinkedIn profiles and Company Pages are separate channels with the same settings. Company Pages also support automatic reposts and plugs.

Example prompts for LinkedIn

• "Write a LinkedIn post from my profile about what we learned this quarter, under 1,300 characters, and save it as a draft."
• "Post these 3 images to our Company Page as a carousel with a short caption on Tuesday 9:00."
• "Add a first comment with the link to the full article."
• "How did our LinkedIn Page posts do in the last 30 days?"
• "Rewrite this post in a more personal tone for my profile and a more formal tone for our Page."

How Claude handles LinkedIn

Claude is at its best when it plans before it writes. Ask for a table of LinkedIn posts first, with a date, the opening line and the post images as a carousel for each, and say OK before it saves anything. In a Claude Project, put your brand notes and the LinkedIn rules you care about in the project instructions, so every chat about LinkedIn starts from them. Claude then calls check_post on each draft, fixes what the LinkedIn rules flag, such as text over 3,000 characters, and only then calls schedule_post.

More prompts in Claude's style

• "Make a table of 4 LinkedIn posts for next month, 1 a week, with the date, the first line and why it matters. Wait for my OK, then save them as drafts."
• "Read the 3 LinkedIn posts I published last, tell me what they have in common, and write the next one in the same style."
• "Check this LinkedIn draft against the channel rules and fix anything that breaks them before you schedule it."

Before Claude schedules a LinkedIn post

• The channel is connected in Postozo and shows in list_channels.
• The text is under 3,000 characters.
• You have seen the text, the time and the channel, and said yes.

What the call looks like

You never have to write this yourself. It shows what Claude sends to schedule_post for LinkedIn, with real setting keys:

{
  "type": "schedule",
  "date": "2026-10-01T09:30:00+05:30",
  "content": "Your LinkedIn text",
  "channels": [
    {
      "channelId": "YOUR_LINKEDIN_CHANNEL_ID",
      "settings": {
        "carousel": true
      }
    }
  ],
  "thread": [
    {
      "content": "First comment",
      "delay": 5
    }
  ]
}

Set up Claude

Add Postozo to Claude as a custom connector. Then ask Claude in plain English to plan, write and schedule posts on your connected channels. Connection: OAuth sign-in. Full steps are on the Claude setup page. Your LinkedIn account must be connected in Postozo first: see the LinkedIn scheduler.

Also works with ChatGPT and Cursor.

Tips for LinkedIn posts written with Claude

• Tell Claude who the post is for and what you want people to do. "Write a LinkedIn post for small shop owners that asks them to book a demo" works better than "write a post".
• Start the chat with a few lines about your tone and the words to use or avoid. Claude writes the text itself, so it needs this to sound like you.
• Ask for 2 or 3 versions and pick 1. It is faster than asking for changes 5 times.
• Say "save as drafts" when you want to check the posts on the calendar before they are scheduled.
• Add 1 detail only you know, like a real number from your business or a customer question. It makes the post yours.
