Custom connector : pass UI values to StartLogin function

[ochaoui]

Hi Folks,

I am developing a custom connector where the user write down on the UI :

- the API URL

- the client_id

-the client_secret

I would like to know how to pass the client_id and client_secret to my  StartLogin and  FinishLogin ?

Thanks in advance.

Hi @ochaoui 

1. Create a Data Source definition

//
// Data Source definition
//
GithubSample = [
    Authentication = [
        OAuth = [
            StartLogin = StartLogin,
            FinishLogin = FinishLogin
        ]
    ],
    Label = Extension.LoadString("DataSourceLabel")
];

2. Provide details so the M engine can start the OAuth flow.

The following code snippet describes how to implement a StartLogin function to start the login flow. 

StartLogin = (resourceUrl, state, display) =>
        let
            AuthorizeUrl = "https://github.com/login/oauth/authorize?" & Uri.BuildQueryString([
                client_id = client_id,
                scope = "user, repo",
                state = state,
                redirect_uri = redirect_uri])
        in
            [
                LoginUri = AuthorizeUrl,
                CallbackUri = redirect_uri,
                WindowHeight = windowHeight,
                WindowWidth = windowWidth,
                Context = null
            ];

Hi @Anonymous ,

Thanks for your reply but it does not reply to my problem.

I found the solution to get those values :

StartLogin = (clientApplication, dataSourcePath, state, display) =>
    let
      authorizeUrl = AUTHORIZE_URI & "?" & Uri.BuildQueryString([
        response_type = "code",
        client_id = Json.Document(dataSourcePath)[client_id],  
        redirect_uri = REDIRECT_URI,
        state1 = state,
        scope = GetScopeString(SCOPES, SCOPE_PREFIX)
      ])
    in
      [
        LoginUri = authorizeUrl,
        CallbackUri = REDIRECT_URI,
        WindowHeight = WINDOW_HEIGHT,
        WindowWidth = WINDOW_WIDTH,
        Context = null
      ];

You need to parse the "dataSourcePath" variable.
