Use Dash to Build to Web Apps on Stripe Data

The CData Python Connector for Stripe enables you to create Python applications that use pandas and Dash to build Stripe-connected web apps.

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

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

Connecting to Stripe Data

Connecting to Stripe 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.

Use the OAuth authentication standard to connect to Stripe. To authenticate using OAuth, you will need to register an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

After installing the CData Stripe Connector, follow the procedure below to install the other required modules and start accessing Stripe 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 Stripe 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.stripe as mod
import plotly.graph_objs as go

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

cnxn = mod.connect("OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;OAuthSettingsLocation=/PATH/TO/OAuthSettings.txt")")

Execute SQL to Stripe

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 Email, Discount FROM Customers WHERE Delinquent = 'False'", 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-stripeedataplot'

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 Stripe data and configure the app layout.

trace = go.Bar(x=df.Email, y=df.Discount, name='Email')

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='Stripe Customers 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 Stripe data.

python stripe-dash.py
