Need Cookie in my Rest API Custom data connector - Help please.

// This file contains your Data Connector logic
section SynDNA;

[DataSource.Kind="SynDNA", Publish="SynDNA.Publish"]
shared SynDNA.Feed = Value.ReplaceType(SynDNAImpl, type function (url as Uri.Type) as any);

SynDNAImpl = (url as text) =>

        Credential = Extension.CurrentCredential(),

        CredentialConnectionString = [ UID = Credential[Username], PWD = Credential[Password] ],

       login = Record.ToTable(Json.Document(Web.Contents(url & "/api/login/" & CredentialConnectionString[UID] & "/" & CredentialConnectionString[PWD], [ Headers = DefaultRequestHeaders ]))),
       FilterLogin = Table.SelectRows(login, each _[Name] = "hash" ),
       hash = List.First(Table.Column(FilterLogin, "Value")),
       //source = Web.Contents(url & "/api/report/1/output/Reports/Angus/test_test?auth=" & hash, [ Headers = DefaultRequestHeaders ]),
       source = Web.Contents(url & "/api/reports/search?auth=" & hash & "&keyword=EXCEL", [ Headers = DefaultRequestHeaders ]),
       json = Json.Document(source)
    in json;

     DefaultRequestHeaders = [

    #"OData-MaxVersion" = "4.0"                             // we only support v4

// Data Source Kind description

         UsernamePassword = []

I need a way to generate a cookie to pass to my API. In the code above has a key borrowed from making my request in Chrome. This request works in any browser and curl. But in Visual Studio it doesn't add the Cookie as part of a default request header. If I manually add the cookie from a browser request (like I have above the request works) if not I get a 403 error. Help please.

Its been quite some time and I'm still trying to get information on this. I know we would go out of vacation soon or some would already be on vacation. I would appreciate any inputs before we all head out to our vacation. 


Wishing you all happy holidays.

Did any of you get through the cookies process? I'm having a hard time working with cookies in power query. There is no information online about it and no doc that can be referred to, making it even more difficult. I see one more post where it was mentioned that the cookies were not allowed due to security reasons in past:

Hello Team


I'm still chasing for the information on cookies. I would appreciate any response.
