How to get access token for creating dataset in Power BI through REST API from Rails APP

Question

Currently, I have only client_id and client_secret, what other parameter do I need for creating a dataset

Answer 1

• First of all we have to connect our Azure AD and power BI application.

def index

  update_token

  if session['access_token']

  redirect_to YOUR_ACTION

  else

    client = get_client

    a = client.auth_code.authorize_url(:client_id => CLIENT_ID, :resource => RESOURCE_ID, :redirect_uri => REDIRECT_URI)

    redirect_to(a) 

  end

end

def callback

  begin

    @code = params[:code]

    client = get_client

    token = client.auth_code.get_token(@code, :redirect_uri => REDIRECT_URI, )

    session['access_token'] = token.token

    if token.token.present?

     YOUR_ACTION

    end

  end

end

def update_token

  token = session['access_token']

  refresh_token = session['refresh_token']

  expire_at = session['expire_at']

  @access_token = OAuth2::AccessToken.from_hash(get_client, { :access_token => token, :refresh_token =>  refresh_token, :expire_at => expire_at, :header_format => 'Bearer %s' } )

  if @access_token.expired?

   @access_token = @access_token.refresh!;

   session['access_token'] = @access_token.token

   session['refresh_token'] = @access_token.refresh_token

   session['expire_at'] = @access_token.expire_at  

   session['instance_url']  = @access_token.params['instance_url']

  end

end

def get_client

  client = OAuth2::Client.new(CLIENT_ID, CLIENT_SECRET, :site => AUTHORITY, :authorize_url =>  AUTHORIZE_URL, :token_url => TOKEN_URL )

  client

end

def azure

  callback

end
