Upload and Get Presigned URL

AI-generated

Overview

This node uploads a file to an S3/MinIO bucket and immediately generates a presigned URL for the uploaded file. It is useful for scenarios where you want to upload files and provide temporary access URLs for those files, such as sharing files securely or integrating with applications that require temporary file access.

Use Case Examples

  1. Uploading a user profile image to a MinIO bucket and generating a presigned URL to share the image with other services.
  2. Uploading a document to an S3 bucket and providing a temporary download link to clients.

  • Errors related to permissions may occur if the provided credentials do not have sufficient rights to upload files or generate presigned URLs.
  • Ensure the binary input field name matches the actual binary data field in the input when uploading binary files.
