Hi Anonymous: Thank you for your reply. My coding and syntax skills are very limited. How would the code for https://boardgamegeek.com/xmlapi2/collection?username=Zenly&stats=1 with wait-retry pattern look like? 

 

let
    Source = Xml.Tables(Web.Contents("https://boardgamegeek.com/xmlapi2/collection?username=Zenly&stats=1")),

    waitForResult = Value.WaitFor(
        (iteration) =>
            let
                result = Web.Contents(url, [ManualStatusHandling = {500}, IsRetry = iteration > 0]),
                status = Value.Metadata(result)[Response.Status],
                actualResult = if status = 500 then null else result
            in
                actualResult,
        (iteration) => #duration(0, 0, 0, Number.Power(2, iteration)),
        5)
in
    if waitForResult = null then
        error "Value.WaitFor() Failed after multiple retry attempts"
    else
        waitForResult
