I have an azure function which has been called every 5minutes. The function takes less than a min to respond but sometimes took longer than normal and causes some logical issues in my app. How can I cancel the request if takes more than x min (e.g. 4min)?

var response = await client.GetStringAsync()

    You have two choices:

    1. Set timeout for your HttpClient

    client.Timeout = TimeSpan.FromMinutes(4);
    
    try
    {
        var response = await client.GetStringAsync();
    }
    catch (TaskCanceledException)
    {
        // your logic when timeout happens
    }
    

    2. Cancel async task

    var cts = new CancellationTokenSource()
    cts.CancelAfter(4 * 60 * 1000);
    
    try
    {
        var response = await client.GetStringAsync(uri, cts.Token);
    }
    catch (TaskCanceledException)
    {
         // your logic when timeout happens
    }
