Facebook publishing as software
Codex runs postqueen commands, reads the JSON results and verifies each step, so your Facebook pipeline behaves like any other task it automates in CI or cron.
FacebookAutomate Facebook with Codex
Point Codex at the postqueen CLI and it creates, schedules and verifies Facebook posts as one repeatable task you can rerun any time.
Quick start
Set up the CLI inside the workspace Codex uses, then describe the Facebook 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 Facebook posts# from notes.md and schedule them# with postqueen"What Codex can run on Facebook
Windows that fit Facebook
Tell Codex when your followers are most active and it schedules posts into that window on Facebook, day after day, without reminders.
Community rules respected
Codex targets the exact pages you choose and keeps every submission reviewable, so you can check each one against community rules first.
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 Facebook until you do.
Three steps to a full queue
Discover Facebook
Codex calls postqueen to list your connected pages and sees what Facebook supports, so drafts start from real capabilities, not guesses.
Draft with Codex
Give it the brief. The agent writes Facebook-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 Facebook allows
Codex reads these limits from postqueen before it composes, so a draft that would be rejected never reaches the queue.

F.A.Q.
Frequently asked questions
How does Codex connect Facebook 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 Facebook posts reliably.
Can Codex schedule Facebook 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 Facebook 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 Facebook and other channels too?
Yes. postqueen connects 30 channels, so Codex can turn the same brief into Facebook 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 from Facebook to Instagram and Threads?
Yes. Write once, select the Facebook Page plus your Instagram and Threads accounts, and adjust each version before scheduling. Every network gets its own native post through its own API, so nothing shows up as a shared link from somewhere else.
What Facebook analytics does postqueen show?
postqueen reports the post-level metrics Facebook's API exposes for your Pages, such as reach, reactions, comments and shares, plus how your Page follower count moves over time. Use it to compare formats and posting slots instead of guessing.
