Use Dash to Build to Web Apps on Auth0 Data

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData API Driver for Python, the pandas module, and the Dash framework, you can build Auth0-connected web applications for Auth0 data. This article shows how to connect to Auth0 with the CData Connector and use pandas and Dash to build a simple web app for visualizing Auth0 data.

With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Auth0 data in Python. When you issue complex SQL queries from Auth0, the driver pushes supported SQL operations, like filters and aggregations, directly to Auth0 and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Auth0 Data

Connecting to Auth0 data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

Start by setting the Profile connection property to the location of the Auth0 Profile on disk (e.g. C:\profiles\Auth0.apip). Next, set the ProfileSettings connection property to the connection string for Auth0 (see below).

Auth0 API Profile Settings

Create a Machine to Machine application in your Auth0 Dashboard under Applications, then authorize it for the Auth0 Management API with the required scopes.

After installing the CData Auth0 Connector, follow the procedure below to install the other required modules and start accessing Auth0 through Python objects.

Install Required Modules

Use the pip utility to install the required modules and frameworks:

pip install pandas
pip install dash
pip install dash-daq

Visualize Auth0 Data in Python

Once the required modules and frameworks are installed, we are ready to build our web app. Code snippets follow, but the full source code is available at the end of the article.

First, be sure to import the modules (including the CData Connector) with the following:

import os
import dash
import dash_core_components as dcc
import dash_html_components as html
import pandas as pd
import cdata.api as mod
import plotly.graph_objs as go

You can now connect with a connection string. Use the connect function for the CData Auth0 Connector to create a connection for working with Auth0 data.

cnxn = mod.connect("Profile=C:\profiles\Auth0.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;")

Execute SQL to Auth0

Use the read_sql function from pandas to execute any SQL statement and store the result set in a DataFrame.

df = pd.read_sql("SELECT Id, TriggerId FROM ActionBindings WHERE DisplayName = 'my-action-binding'", cnxn)

Configure the Web App

With the query results stored in a DataFrame, we can begin configuring the web app, assigning a name, stylesheet, and title.

app_name = 'dash-apiedataplot'

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.title = 'CData + Dash'

Configure the Layout

The next step is to create a bar graph based on our Auth0 data and configure the app layout.

trace = go.Bar(x=df.Id, y=df.TriggerId, name='Id')

app.layout = html.Div(children=[html.H1("CData Extension + Dash", style={'textAlign': 'center'}),
	dcc.Graph(
		id='example-graph',
		figure={
			'data': [trace],
			'layout':
			go.Layout(title='Auth0 ActionBindings Data', barmode='stack')
		})
], className="container")

Set the App to Run

With the connection, app, and layout configured, we are ready to run the app. The last lines of Python code follow.

if __name__ == '__main__':
    app.run_server(debug=True)

Now, use Python to run the web app and a browser to view the Auth0 data.

python api-dash.py
