Why Use the Instagram Upload API?

Automate Your Content Pipeline

Stop manually uploading videos. Integrate our API into your content management system and publish to Instagram automatically whenever new content is ready.

Build SaaS Products

Create social media management tools, video publishing platforms, or marketing automation software powered by our Instagram API infrastructure.

Scale Agency Operations

Manage dozens of client Instagram accounts programmatically. Bulk upload, schedule, and monitor performance without manual work.

Cross-Platform Publishing

Combine our Instagram API with YouTube Shorts, Instagram Reels, and Facebook APIs to publish the same video everywhere from a single codebase.

API Features & Benefits

Simplified OAuth2 Flow

We handle the complex OAuth2 authentication with Instagram. No need to maintain token refresh logic or deal with session expiration.

Automatic Video Transcoding

Upload videos in any format. Our server-side FFmpeg processing converts them to Instagram's requirements (codec, resolution, aspect ratio).

Webhook Event Notifications

Receive real-time callbacks when uploads succeed, fail, or when authentication expires. Build reactive applications without polling.

Unified API Interface

Same request format for Instagram, TikTok, YouTube, and Instagram. Switch platforms without rewriting your integration code.

FAQ

Common Questions

Still stuck? Read the docs or start free and see for yourself.

What programming languages are supported?

Our REST API works with any language that can make HTTP requests. We provide official SDKs for Python and Node.js.

What are the rate limits?

Limits follow your plan and each platform: the Free plan includes 13 uploads a month, paid plans have unlimited uploads, and each platform's own daily posting caps per account still apply. Check an account's remaining quota anytime with GET /api/v1/limits/:accountId.

Can I schedule videos via API?

Yes! Include a "schedule_date" field with an ISO 8601 timestamp (up to 6 months ahead) in your request. We'll queue the video and publish it automatically at the scheduled time.
