ASP.NET core HttpGet single Web API

问题:

Good Morning,

I’m having difficulty setting up my HTTPGETs and then testing the solution in Postman.

I’m trying to return a single result on both occasions however when I input the parameters nothing loads. So I'm clearly missing something which i need some help on please.

I have 1 parameter {id} in my CashMovementController and if I navigate to localhost/api/cashmovements/{id} it loads however if pass the {id} parameter in postman it fails.

Then in my BondCreditRatingsController I have 2 parameters {ISIN} & {Date} and again I'm not sure how to approach this.

Love to hear some advice/help on this please

Thanks GWS
