Use pandas and other modules to analyze and visualize live Xero data in Python.
The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Python Connector for Xero, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Xero-connected Python applications and scripts for visualizing Xero data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Xero data, execute queries, and visualize the results.
With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Xero data in Python. When you issue complex SQL queries from Xero, the driver pushes supported SQL operations, like filters and aggregations, directly to Xero and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to Xero Data
Connecting to Xero 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.
To connect, set the Schema connection property in addition to any authentication values. Xero offers authentication for private applications, public applications, and partner applications. You will need to set the XeroAppAuthentication property to PUBLIC, PRIVATE, or PARTNER, depending on the type of application configured. To connect from a private application, you will additionally need to set the OAuthAccessToken, OAuthClientId, OAuthClientSecret, CertificateStoreType, CertificateStore, and CertificateStorePassword.
To connect from a public or partner application, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL, or you can register an app to obtain your own OAuth values.
See the "Getting Started" chapter of the help documentation for a guide to authenticating to Xero.
Follow the procedure below to install the required modules and start accessing Xero through Python objects.
Install Required Modules
Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:
pip install pandas pip install matplotlib pip install sqlalchemy
Be sure to import the module with the following:
import pandas import matplotlib.pyplot as plt from sqlalchemy import create_engine
Visualize Xero Data in Python
You can now connect with a connection string. Use the create_engine function to create an Engine for working with Xero data.
engine = create_engine("xero:///?InitiateOAuth=GETANDREFRESH&OAuthSettingsLocation=/PATH/TO/OAuthSettings.txt")
Execute SQL to Xero
Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.
df = pandas.read_sql("SELECT Name, QuantityOnHand FROM Items WHERE Name = 'Golf balls - white single'", engine)
Visualize Xero Data
With the query results stored in a DataFrame, use the plot function to build a chart to display the Xero data. The show method displays the chart in a new window.
df.plot(kind="bar", x="Name", y="QuantityOnHand") plt.show()
