How to use AWS S3 REST API ListObjects(v2) with multiple parent/child bucket directories?

Question

What am I missing here?

I'm able to list objects no problem using the aws cli and this command:

aws s3 ls s3://bucket.mycompany.com/parent-dir1/parent-dir2/

But using the REST API via Postman, an equivalent request returns an empty response.

• Tool: Postman
• Method: GET
• URl:
  • https://bucket.mycompany.com.s3.amazonaws.com/parent-dir1/parent-dir2/?list-type=2
• Auth:
• Headers:
  • I've tried with no headers and with x-amz-content-sha256 UNSIGNED-PAYLOAD
  • Message says "This is a duplicate header and will be overridden..." when I try to use this header
• Response:
• Status 200 but response is empty(There are MANY files in parent-dir2).
