I already have an API where I already have Account settings and preferences.

Request URI: PUT consumer/banking/v{version:apiVersion}/preferences?userId={userId}

Sample request body:

{ "accounts": { "89a5503947a755929cd3c03fee28e8c5822f8428466f7212aa4f2be529b062e4": { "order": 1, "preferences": { "balancePeek": "true", "display Name": "My Checking Account", "visible": "true"

Now my question is - Want to create an option of statement, where statement could be E-statement or paper statement with color indication..

Where user can fetch statement by mail, email or on mobile screen according to their preference date. And i also need to JSON request and response code. whereas it was previously put but now i want to patch.

This is 3rd time i am asking the question, if any expert can give exact solution please give me otherwise please do not give.
