Hello
@Arunkumar Manoharan,
AWS requires the creation of a JWT in order to get a valid access token. There are a few steps involved for that. From the looks of it, you're trying to build your own connector for this instead of using the free connector already available on the DX.
I would suggest you download the following two connectors as they should make your life easier.
AWS S3 ConnectorAWS REST API Utility (this covers the JWT generation stuff)
