Access Power BI API with Python

This works for me. 

Reporting Class: Using single user access with app owns data

class EmbedToken:
    def __init__(self, report_id, group_id, settings=None):
        self.username = 'USER'
        self.password = 'PASSWORD'
        self.client_id = 'CLIENT ID'
        self.report_id = report_id
        self.group_id = group_id
        if settings is None:
            self.settings = {'accessLevel': 'View', 'allowSaveAs': 'false'}
        else:
            self.settings = settings
        self.access_token = self.get_access_token()
        self.config = self.get_embed_token()

    def get_access_token(self):
        data = {
            'grant_type': 'password',
            'scope': 'openid',
            'resource': r'https://analysis.windows.net/powerbi/api',
            'client_id': self.client_id,
            'username': self.username,
            'password': self.password
        }
        response = requests.post('https://login.microsoftonline.com/common/oauth2/token', data=data)
        return response.json().get('access_token')

    def get_embed_token(self):
        dest = 'https://api.powerbi.com/v1.0/myorg/groups/' + self.group_id \
               + '/reports/' + self.report_id + '/GenerateToken'
        embed_url = 'https://app.powerbi.com/reportEmbed?reportId=' \
                    + self.report_id + '&groupId=' + self.group_id
        headers = {'Authorization': 'Bearer ' + self.access_token}
        response = requests.post(dest, data=self.settings, headers=headers)
        self.token = response.json().get('token')
        return {'token': self.token, 'embed_url': embed_url, 'report_id': self.report_id}

    def get_report(self):
        headers = {'Authorization': 'Bearer ' + self.token}
        dest = 'https://app.powerbi.com/reportEmbed?reportId=' + self.report_id + \
               '&groupId=' + self.group_id
        response = requests.get(dest, data=self.settings, headers=headers)
        return response

Django View

def index(request):
... irrelevant Code...
    conf = EmbedToken(report.get('report_id'), report.get('group_id'))
    token = conf.get_embed_token()
    return render(request, 'unfi_breakout/unfi_breakout.html', {'selectedReport': token.get('report_id'),
                                                                'embedToken': token.get('token')})

HTML

{% extends extension %}
{% load staticfiles %}
{% block main %}

<div id="reportContainer" style="height: 100% ">
    <script src="{% static 'PowerBi/dist/powerbi.js' %}"></script>
    <script>
    var models = window['powerbi-client'].models;

    var embedConfiguration = {
        type: 'report',
        id: '{{ selectedReport }}',
        embedUrl: 'https://app.powerbi.com/reportEmbed',
        tokenType: models.TokenType.Embed,
        accessToken: '{{ embedToken }}',
        settings: {
              filterPaneEnabled: false
            }
    };

    var element = document.getElementById('reportContainer');
    var report = powerbi.embed(element, embedConfiguration);
    </script>
</div>
</div>

{% endblock %}
