Instagram publishing as software
Codex runs postqueen commands, reads the JSON results and verifies each step, so your Instagram pipeline behaves like any other task it automates in CI or cron.
InstagramAutomate Instagram with Codex
Point Codex at the postqueen CLI and it creates, schedules and verifies Instagram posts, stories and reels as one repeatable task you can rerun any time.
Quick start
Set up the CLI inside the workspace Codex uses, then describe the Instagram 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 Instagram posts# from notes.md and schedule them# with postqueen"What Codex can run on Instagram
Windows that fit Instagram
Tell Codex when your followers are most active and it schedules posts into that window on Instagram, day after day, without reminders.
Media attached, sized right
Images upload in the same postqueen call, so Instagram posts, stories and reels 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 Instagram until you do.
Three steps to a full queue
Discover Instagram
Codex calls postqueen to list your connected accounts and sees what Instagram supports, so drafts start from real capabilities, not guesses.
Draft with Codex
Give it the brief. The agent writes Instagram-shaped posts, stories and reels 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 Instagram 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 Instagram 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 Instagram posts, stories and reels reliably.
Can Codex schedule Instagram 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 Instagram 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 Instagram and other channels too?
Yes. postqueen connects 30 channels, so Codex can turn the same brief into Instagram posts, stories and reels 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 reels to TikTok and YouTube Shorts?
Yes. Compose the vertical video once, select Instagram, TikTok and YouTube as destinations, and adjust the caption per platform before scheduling. Each network gets its own native upload, not a watermarked repost.
What Instagram analytics does postqueen show?
postqueen tracks the post-level engagement metrics Instagram's API exposes, such as likes, comments and reach, plus how your follower count moves over time. Use it to compare formats and time slots instead of guessing.
