Upload Files to Oracle Object Storage Using putObject

Hi -

Does anyone have tips on how to leverage the putObject API request to upload files into object storage?

I've tried running it through Postman using my user name & auth token, but am getting the following error:

{
    "code": "NotAuthenticated",
    "message": "The required information to complete authentication was not provided."
}

I am able to pull objects from Object Storage into my EPM apps using the EPM API via Postman:

Any advice on how to work with putObject would be much appreciated!
