Calling two different APIs with different authentication requirements

Hi,

I tried your example, but had the same issue as before.

I have written a function very similar to the one that you shared. 

However, when I try and run it within my script which uses an API with different credential requirements, it causes an issue in Power BI Desktop:

Here is an example snippet of my code:

//
// Data Source definition
//
[DataSource.Kind="Nexar_PKCESample", Publish="Nexar_PKCESample.Publish"]
shared Nexar_PKCESample.Contents = (url) =>
    let
        accessToken = Extension.CurrentCredential()[access_token],
        url = "https://api.nexardev.com/graphql",
        
        contents = GetReport(accessToken)
    in
        contents;

//
// Data Source Kind definition
//
Nexar_PKCESample = [
    Authentication = [
        OAuth = [
            //
            //Authentication for reporting API
            //
            StartLogin = StartLogin,
            FinishLogin = FinishLogin,
            Refresh = Refresh
        ]
    ],
    Label = Extension.LoadString("DataSourceLabel")
];


//TinyURL URL shortening
GetReport = (accessToken) =>
    let
        //...
        //Original script to get URL from a different API using the accessToken
        //...

        //Long URL from script above
        longUrl = "https://www.examplelongurl.com",
        shortUrl = shortenUrl(longUrl)
    in
        shortUrl;

//Script for URL shortening
shortenUrl = (longUrl) =>
    let
       
        tinyUrl = "https://api.tinyurl.com/create?api_token=<MYTOKEN>",
        json_data = Json.FromValue([url = longUrl]),
        response = Web.Contents(
            tinyUrl, 
            [    
                Content = json_data,
                Headers = [#"Content-Type" = "application/json"]
            ]
        ),
        #"JSON" = Json.Document(response),
        shortUrl = #"JSON"[data][tiny_url]
    in
        shortUrl;

Here is the script for the self contained connector to tinyUrl:

// This file contains your Data Connector logic
[Version = "1.0.0"]
section tinyUrl;

[DataSource.Kind="tinyUrl", Publish="tinyUrl.Publish"]
shared tinyUrl.Contents = (optional message as text) =>
    let
         longUrl="https://123testing.com",
        tinyUrl = "https://api.tinyurl.com/create?api_token=XcBFxMQDD4cmCQRavoSQdpiBjbdlkOElemeym5ObvwbvcAckIng7IyIejAE1",
        tinyUrlToken="XcBFxMQDD4cmCQRavoSQdpiBjbdlkOElemeym5ObvwbvcAckIng7IyIejAE1",
        json_data = Json.FromValue([url = longUrl]),
        response = Web.Contents(
            tinyUrl, 
            [    
                Content = json_data,
                Headers = [#"Content-Type" = "application/json"]
            ]
        ),
        #"JSON" = Json.Document(response),
        shortUrl = #"JSON"[data][tiny_url]
    in
        shortUrl;

// Data Source Kind description
tinyUrl = [
    Authentication = [
        // Key = [],
        // UsernamePassword = [],
        // Windows = [],
        Anonymous = []
    ],
    Label = "tinyUrl connector"
];

// Data Source UI publishing description
tinyUrl.Publish = [
    Beta = true,
    Category = "Other",
    ButtonText = { Extension.LoadString("ButtonTitle"), Extension.LoadString("ButtonHelp") },
    LearnMoreUrl = "https://powerbi.microsoft.com/",
    SourceImage = tinyUrl.Icons,
    SourceTypeImage = tinyUrl.Icons
];

tinyUrl.Icons = [
    Icon16 = { Extension.Contents("tinyUrl16.png"), Extension.Contents("tinyUrl20.png"), Extension.Contents("tinyUrl24.png"), Extension.Contents("tinyUrl32.png") },
    Icon32 = { Extension.Contents("tinyUrl32.png"), Extension.Contents("tinyUrl40.png"), Extension.Contents("tinyUrl48.png"), Extension.Contents("tinyUrl64.png") }
];

When I run only that function in its own, self contained connector, I see this:

I can set the credentials using "Power Query SDK" > "Set Credentials" in the bottom left corner of Visual Studio.

Is there a way to do that programmatically, rather than manually?
