From ChatGPT draft to LinkedIn queue
The writing already happens in ChatGPT. With the public API or the CLI, the same conversation can create scheduled LinkedIn posts instead of text to paste.
LinkedInAutomate LinkedIn with ChatGPT
Draft LinkedIn posts in ChatGPT, then let postqueen schedule and publish them. One conversation in, a full LinkedIn queue out.
Quick start
Point a custom GPT action at the public API, or let agent modes that run commands use the CLI for LinkedIn.
Custom GPT or CLI
# Custom GPT action: call the public APIPOST https://api.postqueen.ai/public/v1/postsAuthorization: your_api_key # Or in agent modes that run commands:npm install -g postqueenpostqueen posts:create --json linkedin-week.jsonWhat ChatGPT can run on LinkedIn
Windows that fit LinkedIn
Tell ChatGPT when your followers are most active and it schedules posts into that window on LinkedIn, day after day, without reminders.
Media attached, sized right
Images upload in the same postqueen call, so LinkedIn posts arrive with their media in place instead of a bare link.
Drafts until you are ready
Ask ChatGPT for drafts only. They sit on the postqueen calendar unscheduled, so you can edit them and pick the time yourself, and nothing reaches your followers on LinkedIn until you do.
Three steps to a full queue
Discover LinkedIn
ChatGPT calls postqueen to list your connected profiles and company pages and sees what LinkedIn supports, so drafts start from real capabilities, not guesses.
Draft with ChatGPT
Give it the brief. The agent writes LinkedIn-shaped posts and proposes publish times that match when your followers are around.
Check and publish
Look over the queue on the postqueen calendar and change anything you want. postqueen publishes each post at its time, and ChatGPT can pull the results after.
What LinkedIn allows
ChatGPT reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.
- Post length
- Up to 3,000 characters per post
- Images
- Up to 9 images in a multi-image post
- Video
- Up to 10 minutes and 5 GB per native video
- Image aspect ratios
- From 1.91:1 landscape to 1:1 square and 4:5 portrait
- Destinations
- Personal profiles and company pages, with an admin role needed for a page
- Token lifetime
- LinkedIn access tokens expire after about 60 days, so connections need a periodic reconnect

F.A.Q.
Frequently asked questions
How does ChatGPT connect LinkedIn to postqueen?
Through the public API from a custom GPT action, or through the CLI in agent modes that execute commands. Both use the same API key and cover LinkedIn posts end to end.
Can ChatGPT schedule LinkedIn posts at exact times?
Yes. Give it exact slots or a rule like mornings at nine and it sets publish times on the posts it creates, so your followers see them at the right moment.
Will ChatGPT publish to LinkedIn on its own?
Only if you ask it to. Tell it to save drafts and nothing is scheduled: the posts wait on the calendar until you set a time. Tell it to schedule, and they go out at the times you can see, which is the setup most people move to once they trust the output.
Can one brief cover LinkedIn and other channels too?
Yes. postqueen connects 30 channels, so ChatGPT can turn the same brief into LinkedIn posts plus adapted versions for every other channel you run.
Does ChatGPT access cost extra on postqueen?
No. The agent uses your regular API key and plan limits: unlimited posts on every plan, and channel counts from 5 on Creator up to uncapped on Ultimate.
When is the best time to post on LinkedIn?
LinkedIn traffic skews to weekdays and working hours, but the exact slot depends on where your audience works. Schedule similar posts into a few different slots for a couple of weeks, compare them in postqueen analytics, and keep the ones that land.
Can I cross-post LinkedIn content to X and other networks?
Yes. Write once, select LinkedIn plus X, Threads, Mastodon or Bluesky, and edit each version before scheduling. A post built for LinkedIn's 3,000 characters rarely fits X, so the per network trim is worth the extra minute.
