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.

• Method: GET

Here you have to use the ListObjectsV2 operation. To use this operation you must have READ access to the bucket. To use this in an IAM policy you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant permission to others
