You can use the Tests tab in your requests and collections to write tests that will execute when Postman receives a response from the API you sent the request to.

You can write test scripts for your Postman API requests in JavaScript(see this). There are many example in Test script examples.

For your example use this:

const responseJson = pm.response.json();
var test = responseJson._links.scaStatus.href;
//var test = "/consents/12da0088-f48b-4a87-9d9b-29cd66de0825/authorisations/d186b5de-f05e-43ac-9924-c3f504e81291";
 var arr = test.split("/");
console.log(arr[4]);
