    Got it to work. This is my function: 

     

    let
    Source = (VersionsRelevantItemID as number) => let
    VRI = Text.From(VersionsRelevantItemID),
    END_PATH = Text.Combine({"items(", VRI, ")/versions"}),
    Source = Xml.Tables(Web.Contents(
    "https://#####.sharepoint.com/sites/###/_api/web/Lists/getbytitle('sharepointlistname')", [RelativePath = END_PATH])),
    entry = Source{0}[entry],
    #"Removed Other Columns2" = Table.SelectColumns(entry,{"content"}),
    #"Expanded content" = Table.ExpandTableColumn(#"Removed Other Columns2", "content", {"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"}, {"content"}),
    #"Expanded content1" = Table.ExpandTableColumn(#"Expanded content", "content", {"properties"}, {"properties"}),
    #"Expanded properties" = Table.ExpandTableColumn(#"Expanded content1", "properties", {"http://schemas.microsoft.com/ado/2007/08/dataservices"}, {"properties"})
    in
    #"Expanded properties"

Hi s-roberts 

 

Do you get this error in the power BI Service?

 

I have used Chris Webb method in the past and it has worked.

 

What is the URL that you are trying to use?

    In the PBI Service, the web connector does not authenticate. It should be the same credentials as for the sharepoint connectors. 

     

     

    This is my function: 

    let

        Source = (Path) =>

        let

        Host = "https://#####.sharepoint.com/sites/ProgramProcess",

            Source = Xml.Tables(Web.Contents( Host, [RelativePath = Path])),

                entry = Source{0}[entry],

            #"Removed Other Columns2" = Table.SelectColumns(entry,{"content"}),

            #"Expanded content" = Table.ExpandTableColumn(#"Removed Other Columns2", "content", {"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"}, {"content"}),

            #"Expanded content1" = Table.ExpandTableColumn(#"Expanded content", "content", {"properties"}, {"properties"}),

            #"Expanded properties" = Table.ExpandTableColumn(#"Expanded content1", "properties", {"http://schemas.microsoft.com/ado/2007/08/dataservices"}, {"properties"})

        in         #"Expanded properties"

    in    Source

     

    The Path variable is generated in another query of PCO list items. 

    each Path would look like this:  /_api/web/Lists/getbytitle('PCO List')/items(###)/versions

     

    Thanks for your help
