Auto Post Images to Instagram & TikTok - n8n Workflow

This automation lets you upload images to both Instagram and TikTok simultaneously using a unified API — all within n8n.

Here’s how it works:

1. The workflow fetches images from URLs (or you can replace with dynamic content).
2. Renames image files as required for API submission (photo1, photo2, etc.).
3. Merges the images into one payload.
4. Sends the post to Instagram and TikTok using the Upload Post API.

It’s perfect for creators, social media managers, or agencies who want to automate cross-platform image sharing without manual uploads.

You can easily:

• Add or replace images
• Change captions or user credentials
• Modify target platforms

Fully customisable and ready to scale.
