I understand that you want to convert your python code into MATLAB. Referring to the following information might be of good help to you:
url = "http://localhost:5225/api/v1/getvalue?controller=view&item=currenttime";
options = weboptions('Timeout',60); % Setting request timeout to 60 seconds
r = webread(url,options);
d = jsondecode(r);
disp(d.value);
url = "http://localhost:5225/api/v1/putvalue";
putdata = struct('controller', 'View', 'item', 'time', 'value', d.value);
options = weboptions('Timeout',60); % Setting request timeout to 60 seconds
r = webwrite(url, putdata, options);
disp(r.StatusCode);
