@MattWho  Thanks for you response. Use case is basically to only upload file using API, and not to download.  We have an UI which is used upload a file, On click of choose file we were planning to call our backend API which inturn calls NiFi HandleHTTPRequest API.  Authorization will part of UI and API. Also, NiFi API will not be directly exposed externally.      Since we were exploring our options in Nifi, we are trying this approach. If you feel this is not achievable or not the right approach, we can drop this and look into other options. Thank you ... View more

Credentials and region are correct as I'm able to fetch the file if they are directly under home directory (20242323) of the bucket. The issue is fetching files that are under folder/subfolders like "month" or "year" in this case.     ListS3 Properties       FetchS3Object Properties     ... View more
