LinkedIn publishing as software
Codex runs postqueen commands, reads the JSON results and verifies each step, so your LinkedIn pipeline behaves like any other task it automates in CI or cron.
LinkedInAutomate LinkedIn with Codex
Point Codex at the postqueen CLI and it creates, schedules and verifies LinkedIn posts as one repeatable task you can rerun any time.
Quick start
Set up the CLI inside the workspace Codex uses, then describe the LinkedIn outcome you want in the task prompt.
Codex session
# Inside a Codex sessionnpm install -g postqueenexport POSTQUEEN_API_KEY=your_api_key # Then prompt:# "Create this week's LinkedIn posts# from notes.md and schedule them# with postqueen"What Codex can run on LinkedIn
Windows that fit LinkedIn
Tell Codex 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 Codex 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
Codex 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 Codex
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 Codex can pull the results after.
What LinkedIn allows
Codex 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 Codex connect LinkedIn to postqueen?
Install the postqueen CLI where Codex runs commands and export your API key. Every command returns JSON, so the agent can create, schedule and list LinkedIn posts reliably.
Can Codex 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 Codex 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 Codex can turn the same brief into LinkedIn posts plus adapted versions for every other channel you run.
Does Codex 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.
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.
What LinkedIn analytics does postqueen show?
postqueen reports the post-level metrics LinkedIn's API exposes, such as impressions, reactions, comments and shares, plus how your follower count moves. LinkedIn exposes more detail for company pages than for personal profiles, so expect a richer picture there.
