How to retrieve the value from the response body from API Call

Question

I'm trying to retrieve the value from the response body of an API call which looks like this

Response ==> {"result":"7decbf2a870ec5108df1ebd73cbb3525"}

I would only need "7decbf2a870ec5108df1ebd73cbb3525".

I was trying to use String.valueOf(response). I ended up getting something like this [[Ljava.lang.String;@7defb4fb].

snippet try { String resp = (APIUtils.callPostAPI(instanceDetails, apiPath, HEADERS, queryParam, payload, displayValue)); if (!resp.isEmpty()) { String val = String.valueOf(resp); System.out.println("value is " + val.toString()); return val; } else { return null; }

Thanks in Advance.
