Automated Image Upload to SharePoint via n8n

This n8n workflow automates the process of uploading an image to a SharePoint site using Microsoft Graph API. The workflow begins with a manual trigger for testing purposes, then sets up necessary credentials securely. It fetches a sample image from a public URL for demonstration, specifies the target folder and filename in SharePoint, and authenticates via OAuth2 client credentials to obtain an access token. Finally, it uploads the image directly to the specified SharePoint folder, making it ideal for automating file management tasks, especially in content publishing or collaboration scenarios where images need to be programmatically uploaded and organized.
