Getting version history from SharePoint document library

Question

Hi all,&nbsp;&nbsp;I posted a similar issue a whileback but thought I'd try again and phrase myself a little differently.&nbsp;&nbsp;I want to use previous versions of a file I have in Sharepoint.&nbsp;&nbsp;The way I am currently trying uses the REST API to return a list of versions and their URL, which links directly to the content. The Url looks like this:mysite.sharepoint.com/_vti_history/[version]/[path]&nbsp;This URL does exactly what I need, but when I try to load it with Web.Contents(), it amends the url to something that doesn't work:&nbsp;mysite.sharepoint.com/_api/web/GetFileByServerRelativeUrl('_vti_history/[version]/[path]')/$value&nbsp;I am aware that for regular files this would be fine. For previous versions, it isn't.&nbsp;&nbsp;Does anyone know how I can either tell PowerBi to *not* change my Url, or how else I can get previous versions without using a custom connector?&nbsp;

Hi&nbsp;omeallynile&nbsp;
You can try to use web connector with 'relativepath' option:
let
    Source = Web.Contents("https://tenant.sharepoint.com", [Headers=[#"key"=mykey], RelativePath="/_api/GetFileByServerRelativeUrl('[path]')/$value"])
in
    Source

Hi&nbsp;v-diye-msft&nbsp;,&nbsp;&nbsp;Thanks for responding. As mentioned in OP, this does not work when calling from version history. It only works for the current version of a file. Do you have any other ideas?&nbsp;

I know this is an old topic, but after several frustrating hours looking for help online and finding only one or two threads with no solutuions, I buckled down and came up with a solution to this.&nbsp;You can use the M function below to pull a list of all versions of a file in a SharePoint library with an associated URL that will actually work with Web.Contents.&nbsp;Usage (if you named the function Versions):Versions("https://&lt;tenantname&gt;.sharepoint.com", "/&lt;sitename&gt;", "/&lt;path&gt;/&lt;filename&gt;")&nbsp;Function:(SharePointTenant as text, SharePointSite as text, FilePath as text) as table =&gt;letBase = Text.Combine({SharePointTenant,"/sites",SharePointSite,"/_api/Web/GetFileByServerRelativePath(decodedurl='/sites", SharePointSite, FilePath, "')/Versions"}),Source = Xml.Tables(Web.Contents(Base)){0}[entry],Cleaned = Table.RemoveColumns(Source,{"category", "link", "title", "updated", "author"}),Built = Table.TransformColumns(Cleaned, {{"content", (x) =&gt; letr = Record.FieldValues(Record.FieldValues(Record.FieldValues(x{0}){0}{0}){0}{0}){0}{0},ret = [Created = DateTime.From(r[Created]{0}[#"Element:Text"]),Url = Text.Combine({Base, "(", r[ID]{0}[#"Element:Text"], ")/$value"}),VersionLabel = r[VersionLabel],VersionID = r[ID]{0}[#"Element:Text"]]inret}}),Expanded = Table.ExpandRecordColumn(Built, "content", {"Created", "Url", "VersionLabel", "VersionID"}, {"Created", "URL", "VersionIndex", "VersionID"}),Extracted = Table.RenameColumns(Table.TransformColumns(Expanded, {{"id", each Text.End(_, 36), type text}}), {{"id", "GUID"}}),Typed = Table.TransformColumnTypes(Extracted,{{"GUID", type text}, {"URL", type text}, {"VersionIndex", Int64.Type}, {"VersionID", type text}, {"Created", type datetime}}),Organized = Table.ReorderColumns(Typed,{"VersionIndex", "Created", "GUID", "VersionID", "URL"})inOrganized&nbsp;
