Call API using Basic Auth + 2FA

Good afternoon all, looking to verfiy I've not done something wrong.

I'm trying to access the Pulseway RMM API that the documentation states: "uses Basic Authentication which requires an authorization header with the username and password in the username:password format encoded as Base64."


I've done this but I'm getting a "we couldn't authenticate with the credentials provided. Please try again." error message.


When I log in to Pulseway RMM web portal, my organisation requires 2FA in the form of using the Microsoft Authenticator app to generate a one-time 6-digit code - Am I right in thinking this is why I'm getting the failure to authenticate.


After looking around this forum, and the net as a whole, I found a post on this forum by @luiTre that said:


So I've tried updating my Base64 encoded credentials to be username:passcode:password but this doesn't work either. I've tried it using an external encoder like, and I've tried handling the encoding directly in Power Query.


Does anyone have any experience of calling an API that requires Basic Auth + 2FA?


My code:




    URL             =   "",
    Path            =   "v2/systems",
    Username        =   "username",
    OneTimePasscode =   "123456",
    Password        =   "password",
        Credentials     =   Username & ":" & Passcode & ":" & Password,

            Binary = Text.ToBinary(Credentials),
            Base64 = Binary.ToText(Binary, BinaryEncoding.Base64),

    Source = Json.Document(Web.Contents(URL,
            [ RelativePath = Path, 
              Headers = [ Authorization = "Basic " & Base64 ]]))
