Usage of sender_uri parameter of request header

Discussion reference #15

Suggestion - Safer to use a URI configured during the onboarding process and exclude sender_uri in the specification.

Experts , We would like you suggestion on usage of sender_uri header param.

We have received feedback suggesting that the configuration of the sender_uri parameter should be done during the onboarding process instead of being accepted in each request. The initial intention behind including it in the header was to provide flexibility in obtaining responses for each request on different URIs.

We request experts to give input on this.
