Web API expand relations in Power query (M)

[Sabarikumar7579]

I am querying for Azure DevOps data using web API and trying to expand related remote links. I know the web API url which is

https://dev.azure.com/fabrikam/_apis/wit/workitems?ids=297&$expand=relations&api-version=6.0

 I need the above url in Power query format so that it can refresh on PBI services which is like below. 

let Source1 = (Id as text) =>
    let
            Source = VSTS.Contents("https://dev.azure.com/fabrikam/_apis/wit/workitems",
            [
                Query = [ids=Id]                
            ]
              ),
            #"Imported JSON" = Table.FromRecords(Json.Document(Source,65001)[value])
    in
          #"Imported JSON"
in
    Source1

The help I need is to add expand part from the above web API url in the Power query. I am new to using APIs. 

Thanks in advance!!!

Have you tried using a Query record of [ids=Id, #"$expand"="relations"] ?

(The #"..." syntax is M's way of escaping identifier names, which can be used to include characters that aren't normally allowed.)

Yes, that worked.

I was calling the expand outside the "[ ]", which was my mistake. 

Thank you !!!
