API Image Processor AWS

Test API built with .NET 9 to experiment with AWS S3 and SQS integration.
Includes basic endpoints to upload, list, download files, and publish events to a queue.

Features

• POST /upload → Upload a file to S3 (stored under uploads/) and publish metadata to SQS.
• GET /list → List all files in the bucket.
• GET /download?key=... → Download a file by key.

Requirements

• .NET 9 SDK
• AWS S3 bucket + IAM user with permissions (s3:PutObject, s3:GetObject, s3:ListBucket, s3:DeleteObject)
• AWS SQS queue + IAM user with permissions (sqs:SendMessage)

Configuration

The S3 bucket name, base path, and SQS queue URL are defined in appsettings.json:

"S3": {
  "BucketName": "your-bucket-name",
  "BasePath": "uploads"
},
"SQS": {
  "QueueUrl": "https://sqs.<region>.amazonaws.com/<account-id>/<queue-name>.fifo"
}
