Getting Started with M.App Chest

I'd like to develop from my own IDE and now I'm trying to access M.App Chest from my local machine. I've created a ConsumerKey and ConsumerSecret for my app.


To test this I'm running this little code:

    url: '',
    data: {
        response_type: 'token',
        client_id: ConsumerKey,
        scope: 'All',
        redirect_uri: location.href.replace('development.html', 'redirected.html')
}).fail( function( error ) {
    console.log( error );
    document.write( error.responseJSON.error_description );

 Right now this results in a 500 error 'No message available'


If I use the ConsumerKey of an app that's already been promoted and all something else happens:


first, this succeeds:<consumerKey>&s...>


This gets redirected to


Then, finally to


which fails, with this error: 

Redirect from ... has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.


Indeed, the Origin header in the third request is set to null.


Basically my questions are:

  • is it possible to access the OAuth service from scripts outside the Studio? (I've done it before last year, but maybe things have changed?)
  • what is needed to make it work with an app that's still in development?

Re: Getting Started with M.App Chest

I found out.


Apparently the oauth/authorize url is not supposed to be called in an Ajax call, but the user needs to be redirected to that page.


And also: my app-in-development needs to be promoted. I've used the integration tests to assign the app to myself and now I have access.
