automatic refresh webread data

hello everybody

I have a webread data (XXX are confidential):

https://api.XXXXXXXX.com/time_series?apikey=XXXXXXXX&interval=1min&symbol=EUR/USD&timezone=Europe/Rome&end_date=2023-02-14 09:37:00&start_date=2023-02-13 09:37:00&format=CSV')

that I save as table in workspace and analyze it.

how can I get an automatic refresh every 1 minute to this url without copy and launch it manually on command window?

tks very much

create a timer object, use a method for repeated execution and add the callback

EDIT:

e.g.

function doStuff()
intervalInS=10;


myData=[];

everyNowAndThen = timer("Period",intervalInS,"ExecutionMode","fixedRate","TimerFcn",@refresh);

everyNowAndThen.start();

function refresh(~,~)

    myData=webread('https://de.mathworks.com/help/daq/troubleshooting-tips.html');

    disp('next one')

end

end

with this little change the code works and refreshes on command window.

ans =

1000×5 table (answer on command window)

but the problem is that the workspace is empty..no ans in table format...

here the code (so far tks to Jonas. I've replaced his "display"):

function doStuff()
intervalInS=60;
myData=[];
everyNowAndThen = timer("Period",intervalInS,"ExecutionMode","fixedRate","TimerFcn",@refresh);
everyNowAndThen.start();
function refresh(~,~)
    myData=webread('https://api......CSV');
    webread('https://api........CSV')
end
end

[roberto]

when I try your suggestion, this is the result:

function doStuff()

Error: Function definition are not supported in this context. Functions can only be created as local or nested functions in code files.

take ensure my code is working as intended, please copy y cody to a new .m file, save it and run it using

doStuff()

it looks like tried to paste my code to the command line
