Feed Posts

Publish single images, videos, and carousels to the Instagram feed with captions, hashtags, and location tags.

Carousels

Why this page exists

A practical Instagram publishing API for product teams

If you are searching for an Instagram API, the real problem is usually not just transport. You need a stable way to connect accounts, map your content model to Instagram placements, schedule delivery, and handle media constraints without rewriting platform-specific logic in every app.

Ampost gives you a unified publishing layer for Instagram while keeping the request format developer-friendly. Instead of managing separate upload steps, token lifecycles, and placement rules inside your own service, you send content, media URLs, and platform options through one REST workflow.

That makes it a better fit for SaaS products, internal tools, agencies, and AI agents that need repeatable Instagram publishing rather than one-off manual posting.

Use cases

Commerce and product drops

Push catalog imagery, launch announcements, and short-form promo videos to Instagram from your store backend or release pipeline.

Agencies with approval workflows

Generate content in your own CMS, review it internally, then submit final Instagram jobs through a single API instead of juggling platform-native tools.

AI-assisted social publishing

Let agents or automation systems draft captions, assemble media URLs, and schedule posts while Ampost handles platform normalization and delivery.

Post to Instagram in one API call

Connect your Instagram account once, then publish from any backend or AI agent.

curl -X POST https://api.ampost.io/api/v1/posts \
  -H "Authorization: Bearer amp_live_xxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "New product drop 🚀",
    "platforms": ["instagram"],
    "media": [
      { "url": "https://cdn.example.com/photo.jpg", "type": "image" }
    ],
    "options": {
      "instagram": { "placement": "feed" }
    }
  }'

Integration notes

OAuth and platform caveats developers should expect

Instagram publishing still depends on a connected Instagram account and valid Meta authorization. Ampost removes integration friction, but it does not bypass account ownership or platform policy requirements.

Placement support differs by media type. Feed posts, stories, reels, and carousels can require different payload options, so the API keeps placement explicit instead of guessing.

Media quality and aspect ratios matter. Ampost normalizes uploads and handles transcoding, but your source assets should still match the intended Instagram format for the best results.

Build path

Move from proof of concept to production faster

Start with the API reference to understand the request shape, then connect pricing and usage limits to the rollout plan for your own product or automation workflow.

The goal is simple: reduce the amount of Instagram-specific code you own while keeping enough control over captions, media, scheduling, and placement behavior.

FAQ

Common questions about the Instagram API workflow

What can I publish to Instagram with Ampost?

Ampost supports feed posts, stories, reels, and carousels. You send one API request, specify `instagram` in `platforms`, and set placement-specific options when needed.

Do I need to build OAuth and token refresh myself?

No. Ampost handles the account connection flow, stores the credentials, and refreshes long-lived tokens automatically so your service can focus on content and scheduling logic.

Is this only for scheduling, or can I publish immediately too?

Both. You can create Instagram posts for immediate publishing or attach a future publish time and let Ampost process the job later through its scheduler.
