Instagram Image Posting API for Developers

Q: How do I implement Image Posting API for Instagram?

Import your media using POST /v1/media/upload/import, then call POST /v1/posts with the returned path in the publications array. Each publication includes your socialMediaAccountId, platformSettings (with type: "INSTAGRAM" and feature-specific fields), and a posts array with content and attachmentPaths.

Q: Does Image Posting API for Instagram require a platform audit?

No. PostPulse has passed the necessary platform reviews on your behalf. You can use Image Posting API on Instagram immediately, without any developer review or approval process.

Q: Can I use Image Posting API across multiple platforms at once?

Yes. PostPulse supports publishing to multiple platforms in a single API request. Add multiple entries to the publications array, one per platform. The same media and content can be distributed to instagram, linkedin, facebook, twitter, threads, telegram, bluesky simultaneously.

Q: What happens when a Instagram post fails?

PostPulse sends a real-time webhook event (publication.failed or post.failed) to your configured webhook URL. This lets you implement retry logic, user notifications, or logging in your application without polling.

Post single images or photo collections to social media platforms via REST API. Works with Instagram — no platform audit, no complex OAuth setup. Just your access token and a POST request.

How Instagram Image Posting works via PostPulse

The Instagram Image Posting capability in PostPulse lets you post single images or photo collections to social media platforms via rest api. PostPulse handles the platform-level authentication, media processing, and delivery so you can focus on building your product.

PostPulse handles OAuth token management, media validation against Instagram's requirements (formats: JPG, PNG, MP4, MOV), and the async delivery to Instagram's API. Real-time webhook events notify your application when publishing succeeds or fails.

I use PostPulse with an AI agent via their MCP server. My agent literally posts to social media on its own now. Didn’t expect that to work as smoothly as it did.

$5/month for what would otherwise require a full backend engineer to maintain? Easy yes. The REST API is clean and well-documented too, which is rare.

Shawn Padilla

Tried to get TikTok API access myself. Three weeks, two rejections. Switched to PostPulse and was posting to TikTok the same day. Wish I hadn’t wasted that time.

Karen Rivers

I’m a Make.com power user and needed to post to 5 platforms from one scenario. The native PostPulse app for Make connected everything in one afternoon. Would’ve taken me weeks to do manually.

Douglas Finch

I built an n8n automation for a client and needed to add social publishing. The official PostPulse n8n node was literally drag and drop. No headache.

Andrea Scott

Saved me months of dev work. I was about to start integrating Instagram and TikTok APIs separately — then I found out Meta’s app review alone can take months. PostPulse just handled all of that. Shipped social posting in under a week.

The most flexible pricing model on the market!

I'm building an AI content factory as a side hustle. I'm still in the experimentation phase, so I don't have the budget for expensive tools — but I also needed to get everything up and running quickly, so I integrated with a ready-to-go API instead. PostPulse offers a flexible pay-as-you-go model that let me experiment first without commitment — and now that we have stable traffic, I’ve switched to their $5/month subscription.

Best support on the market — the founder personally emailed me when I hit a client error and walked me through the fix.

We optimized the posting to 20 twitter accounts. It was a problem to manage such a number, but through the platform everything works out perfectly. Very convenient dashboard for tracking errors. Great product.
