Automate Twitter Banner with New Followers Using n8n

What This Automation Does

This workflow updates your Twitter profile banner to show up to 3 new follower avatars automatically.
It solves the problem of spending hours editing images and uploading banners manually.
The result is a new banner with perfectly sized and placed follower images that updates without any extra work.

The workflow takes your Twitter followers data as input.
Then it processes each follower’s profile pictures by resizing, cropping into circles, and compositing them onto a custom background.
Finally, it uploads the finished banner back to Twitter.

This is for social media managers or business owners who want to save time.
Anyone who updates Twitter banners manually with follower images can benefit.
No coding experience needed but some familiarity with n8n is helpful.

• Check all URLs in the HTTP Request nodes for correctness.
