PowerBI Custom Connector - Windows Authentication

[Anonymous]

Dear Forum members/gurus,

Greetings, I have a query related to Windows credential/Username.

Is there anyway before sending request to the service I can retrieve Windows username and send it as a header or how the below works if I wanted to use Windows user. I wanted to send Windows user name to the my service where I can get a windows user and do further processing:

Below I have used for Windows authentication:

Sample.DataConnector = [
Authentication = [
Windows = []
],
Label = Extension.LoadString("DataSourceLabel")
];

Then I have a feed method as below, tried to use Extension.CurrentCredential but getting a null error:

Sample.DataConnector.Feed = (url as text) =>
let

Credential = Extension.CurrentCredential(),
split= Text.Split(Credential[Username],"#"),
source = Web.Contents(url, [ManualCredentials = true, Query = [
user_key = split]),
json = Json.Document(source)
in
json;

I would be really grateful if anyone can help me to resolve - In simple I wanted to send windows username from Power bi custom connector and retrieve it within my service (REST)

Hi @Anonymous,

I have gotten the response from the Product Team. 

The Username is only presented with the Alternative Windows Authentication, which asks us to enter Windows username and password. You can activate it like below.

[Authentication = [Windows = [SupportsAlternateCredentials = true]]]

Can this be helpful?

Best Regards,
