How to automate Instagram carousel posts using Supabase uploads?

Help me Build my Workflow
1

Hi everyone,
I’m trying to build a workflow that automatically creates an Instagram carousel post when I upload multiple image files to a Supabase storage folder. The idea is:

1. Detect when new files are uploaded to a specific Supabase folder
2. Collect those files (usually 2–10 images at a time)
3. Upload them to Instagram as a single carousel post using the Facebook Graph API
4. Use the same caption I attach at upload (or store it somehow)
5. Delete the files from Supabase after successful posting

I’m using n8n.cloud, and I’m stuck on how to:

• Detect grouped file uploads as one carousel
• Send multiple images correctly through the Graph API
• Handle access tokens and permissions

Has anyone done something similar or can help with the JSON setup or modules I need?

Thanks in advance!

Hello! Did it work? I’m having the same problem you described.

How are you making those carousel images? Maybe you can try Contentdrips n8n node.

P.S. I’m the founder.
