How to pass a value from one table iteratively to another API request in power bi

Hello sujeesh 

you have to use a custom function for this. Create a table with your IDs, and then apply your custom function on a new column, passing the ID as parameter. I prepared for you a code example (not applying your API quering steps though). You have to put all your code here using "id" instead of your hardcoded one

let
	Source = #table
	(
		{"Release_ID"},
		{
			{"473"},	{"523"},	{"456"},	{"654"},	{"321"}
		}
	),
    QueryAPI = (id)=>
    let 
        //YourStepsGoHere
        // your reading function here("https://vsrm.dev.azure.com/fe-tfs/Advisory%20products/_apis/Release/releases/" & id &"?api-version=5.1-pre..."
    in 
        id,

    AddColumn = Table.AddColumn
    (
        Source,
        "QueryQuery",
        each QueryAPI([#"Release_ID"])
    )

in
	AddColumn

Copy paste this code to the advanced editor in a new blank query to see how the solution works.
