I had a look at the documentation of Postman titled “Authorizing requests | AWS Signature”:

- [Authorizing requests | Postman Learning Center](https://learning.postman.com/docs/sending-requests/authorization/#aws-signature)

From this doc I learned that Postman offers a UI that enables user to configure Postman so that it automatically transfer credential information from ~/.aws/credentials and ~/.aws/config files into the Request Header when [WS.SendRequest()](https://docs.katalon.com/docs/legacy/katalon-studio-enterprise/keywords/web-service-keywords/ws-send-request) is executed.

I think Katalon Studio just lack the equivalent feature.

Now @amyradova has to write some custom Groovy code (an alternative to WS.SendRequest) to transfer the AWS credential from ~/.aws/cerendentails file info into a Request Header runtime.

@Jass, @duyluong

Could you support @amyradova ?
