How to Visualize Avalara AvaTax Data in Python with pandas via CData Connect AI

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Connect AI Python SDK, the pandas and Matplotlib modules, you can build Avalara AvaTax-connected Python applications and scripts for visualizing Avalara AvaTax data. This article shows how to connect to Connect AI and use the pandas and Matplotlib built-in functions to query Avalara AvaTax data and visualize the results.

The Connect AI Python SDK (cdata-connect-ai) is a DB-API 2.0 (PEP 249) compliant client, so pandas can read query results directly from the SDK connection object. There is no driver to install per source and no SQLAlchemy engine to configure: connect with a Personal Access Token and pass the connection straight to pandas.read_sql.

Connect to Avalara AvaTax in Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Avalara AvaTax" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Avalara AvaTax.

   The primary method for performing basic authentication is to provide your login credentials, as follows:

   • User: Set this to your username.
   • Password: Set this to your password.

   Optionally, if you are making use of a sandbox environment, set the following:

   • UseSandbox: Set this to true if you are authenticating with a sandbox account.

   Authenticating Using Account Number and License Key

   Alternatively, you can authenticate using your account number and license key. Connect to data using the following:

   • AccountId: Set this to your Account Id. The Account Id is listed in the upper right hand corner of the admin console.
   • LicenseKey: Set this to your Avalara Avatax license key. You can generate a license key by logging into Avalara Avatax as an account administrator and navigating to Settings -> Reset License Key.
   
4. Click Save & Test
5. Navigate to the Permissions tab and update the user-based permissions.

Generate a Personal Access Token (PAT)

The Python SDK authenticates to Connect AI with your account email and a Personal Access Token (PAT). It is best practice to create a separate PAT for each application to maintain granularity of access.

1. Click the Gear icon () at the top right of the Connect AI app to open the Settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The PAT is only visible at creation, so copy it and store it securely.

Install Required Modules

Install the SDK (with the pandas extra) and Matplotlib using the pip utility:

pip install "cdata-connect-ai[full]"
pip install matplotlib

Import the modules, then connect to Connect AI with your account email and PAT. Identifiers are three-part: <Connection>.<Schema>.<Table>, where the connection name defaults to the source name (for example, AvalaraAvatax1).

import pandas
import matplotlib.pyplot as plt
import cdata_connect_ai

conn = cdata_connect_ai.connect(
    username="[email protected]",
    password="<your_pat>",
)

Query Avalara AvaTax with pandas

Use the read_sql function from pandas to execute a SQL statement and store the result set in a DataFrame. Pass the SDK connection directly, no engine required.

df = pandas.read_sql(
    "SELECT Id, TotalTax "
    "FROM [AvalaraAvatax1].[AvalaraAvatax].[Transactions] "
    "WHERE Code = '051349'",
    conn,
)

Note: pandas may print a UserWarning stating that it only officially supports SQLAlchemy connectables. This is expected when passing a DB-API connection directly—the query runs correctly and the warning is safe to ignore.

Visualize Avalara AvaTax Data

With the query results stored in a DataFrame, use the plot function to build a chart. The show method displays the chart in a new window.

df.plot(kind="bar", x="Id", y="TotalTax")
plt.show()

conn.close()
