Update Twitter Banner with Unsplash Images via HTTP

This workflow demonstrates a simple yet powerful automation for updating Twitter profile banners programmatically. It starts with a manual trigger, fetches a high-quality image from Unsplash using an HTTP Request node configured to download as a binary file, and then uploads it to Twitter's API endpoint (/account/update_profile_banner.json) via another HTTP Request node with form-data-multipart support and OAuth1 credentials.

Key benefits include eliminating manual uploads, enabling scheduled banner refreshes for dynamic social media presence, and serving as a template for other binary file uploads to APIs. It's ideal for marketers maintaining fresh profiles or developers learning n8n's HTTP capabilities with authentication.

Use cases: Periodic banner updates in marketing campaigns, testing Twitter API integrations, or extending to fetch images from other sources like local files or cloud storage. Requires Twitter API credentials setup; replace Unsplash URL for custom images.
