Automated Slack Image Upload and Notification Workflow

This n8n workflow automates the process of handling image uploads via Slack, organizing files in folders, and notifying channels about new uploads. It starts with a webhook trigger, which receives messages and submissions from Slack. The workflow then routes these messages based on their nature—whether they relate to new image uploads, folder selections, or other actions.

Key Steps:

1. The ‘Parse Webhook’ node extracts payload details from Slack messages.

2. Using ‘Route Message’, the workflow determines if the interaction involves a file upload, folder creation, or an existing folder selection.

3. Depending on the user action, modal dialogs are opened for creating new folders or selecting existing folders, utilizing Slack’s modal views.

4. When files are uploaded, they are split out in ‘Split Out Files’, then downloaded with ‘Download File Binary’.

5. Files are uploaded to an S3 bucket, with success or failure responses sent back to Slack.

6. If uploads succeed, the URLs are sent as a message to a specified Slack channel.

This workflow is especially useful for managing and automating bulk image uploads, organizing files efficiently in cloud storage, and keeping team members informed in real-time via Slack notifications. Practical use cases include digital asset management, collaborative content curation, or automated archiving systems.
