AADSTS50001 error on Web API with Azure AD

Hi Mottor,

I find a sample about use power query to call the azure api(not azure ad), perhaps you can reference to below code:

let
    AzureMLJsonToTable = (
        WebServiceURI as text,
        WebServiceKey as text,
        TableToScore as table,
        optional Timeout as number
    ) as any => 
let
    WebTimeout = if Timeout = null then #duration(0,0,0,100) else #duration(0,0,0,Timeout) ,  

    WebServiceContent = ToAzureMLJson(TableToScore),//method which used to convert the table to json

    //example:
    WebServiceURI1 = "https://europewest.services.azureml.net/workspaces/dcfeb7f96e2d431cb836299c27661e1e/services/d6291034e7c44b3ab63f0b26772a583b/execute?api-version=2.0&details=true",
    WebServiceKey1 = "Pxy+NXyx/YZA/YkD0OENmG4awDZGpLeHGFKKf5XgC6sKgJPPO/CUp4tin15N8aMWgpKbu41Nv9/ruWW2rIKUHA==",

    WebResponse = Web.Contents(WebServiceURI,
        [Content = Text.ToBinary(WebServiceContent),
         Headers = [Authorization="Bearer " & WebServiceKey,
                    #"Content-Type"="application/json",
                    Accept="application/json"],
         Timeout = WebTimeout]),
    
    output = AzureMLJsonToTable(WebResponse) // method which used to convert json to table
in
    output 

in
    AzureMLJsonToTable
