Everything You Need to Schedule Instagram Posts

Queue Instagram content without touching Meta's Graph API directly. One endpoint to schedule, reschedule, and cancel feed posts, carousels, and Reels in any timezone.

Exact-Time Delivery

Pass a scheduledFor ISO 8601 datetime and PostPeer publishes the media at that exact moment through the Graph API. No manual reminders, no cron jobs on your side.

Publish at the Right Local Time

Set an IANA timezone like America/Los_Angeles and schedule against your audience local hours. PostPeer resolves the offset, including daylight saving, so media lands when followers are active.

Queue Media and Carousels

Schedule single images, multi-image carousels, and Reels the same way. PostPeer validates each item against Instagram specs before queuing so bad media fails early, not at delivery.

Manage Your Content Calendar

List every queued post, reschedule to a new time, or cancel before delivery. Build a full Instagram editorial calendar on one endpoint.

Plan Content in Advance

Queue a week or a month of posts up front by submitting each with its own scheduledFor time. Line up a campaign and let PostPeer deliver each piece on schedule.

Cross-Post on a Schedule

Queue the same content for Instagram, Facebook, TikTok, and more in one request at the same future time. Platform-specific formatting is handled automatically.
