How to daily refresh my dataset when using odata with token authetication

[htacke]

I have made a dashboard with odata that is authenticated in de Mquery with a token. In PowerBI Desktop i can refresh this data whenever i want.

If i publish it, I publish it with this data and want it refreshed overnight. Now i get an error message: 'Query contains unknown or unsupported data sources'.

How can i make this refrefresh to work?

HI @htacke,

I think you can add new steps at query editor before your 'get data' function.(add variable step to store token which generated from token api)

Then you can use this variable as parameter in your 'get data' method, so you not need worry about token timeout.(each time you refresh, the variable will get new token string from generate token method)

This still doesnt solve my issue.

I can update in Desktop, but not after publishing

HI @htacke,

In fact, custom function only works on power bi desktop, power bi service not support this.

Please modify your function with query parameters.

Using the Power BI Service Parameters to change connection strings (To possibly change between Dev,

We removed the custom functions in the query, but still not able to refresh in powerbi Service.

We have no datasource on the report; the connection string is in the query.

This is our query now:

Still didn't get an answer.

do we need another solution?

I use the following query to get data;

In the desktop it refreshes fine, but i dont get it refreshed automatically when i publish it; i want it to refresh daily

let
 GetOdataPage = (authKey, project, Path) =>
  let
  Source = Json.Document(
   Web.Contents(
    Path,
    [
     Headers = [
      #"Authorization"=authKey,
      #"Selected-Project"=project
     ]
    ]
   )
  ),
  NextList=@Source[value],
  result = try @NextList & @GetOdataPage(authKey, project, Source[#"@odata.nextLink"]) otherwise @NextList
  in
  result,
 GetOdataToken = (url, username, password) =>
  let
  GetJson = Web.Contents(
   url,
   [
    Headers = [
     #"Accept" = "application/json",
     #"Content-Type" = "application/x-www-form-urlencoded"
    ],
    Content = Text.ToBinary ("grant_type=password&username=" & username & "&password=" & password)
   ]
  ),
  FormatAsJson = Json.Document(GetJson),
  AccessToken = FormatAsJson[access_token],
  AccessTokenHeader = "Bearer " & AccessToken
  in
  AccessTokenHeader,
 level = Woningniveau,

 urlTokenApi = Url & "/Token",
 username = UserName,

 token = GetOdataToken(urlTokenApi, username, password),
