Custom connector : pass UI values to StartLogin function

ochaoui — Wed, 24 Nov 2021 14:52:59 GMT

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.

Regards,

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 ];

For more details you may refer to this offical blog: GitHub Connector Sample

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.
