File Upload

The File Upload node uploads files to cloud storage (S3) from within an orchestration. It supports multiple input methods — direct file, base64 string, public URL, or WhatsApp media — and returns a public download URL.

Use Cases

Store files received from a webhook or WhatsApp message in S3
Convert base64-encoded file data to a publicly accessible URL
Mirror files from an external URL into your own storage
Attach uploaded file URLs to records in Airtable or Slack
