Getting Started with the CData Connect AI Python SDK for QuickBooks Online
The CData Connect AI Python SDK (cdata-connect-ai) is a DB-API 2.0 (PEP 249) compliant client that lets you fetch and act on live QuickBooks Online data with standard Python database code. Because Connect AI provides the connectivity: you install one package, authenticate with a Personal Access Token, and query QuickBooks Online (and every other source connected in Connect AI) using the same familiar connect() / cursor() / fetchall() pattern you already know from libraries like sqlite3 and psycopg2.
This guide walks through connecting QuickBooks Online in Connect AI, generating a Personal Access Token, installing the SDK, and reading (and, where supported, writing) live QuickBooks Online data.
Prerequisites
- An account in CData Connect AI
- Python 3.8 or higher
- An active QuickBooks Online account with valid credentials
About QuickBooks Online Data Integration
CData provides the easiest way to access and integrate live data from QuickBooks Online. Customers use CData connectivity to:
- Realize high-performance data reads thanks to push-down query optimization for complex operations like filters and aggregations.
- Read, write, update, and delete QuickBooks Online data.
- Run reports, download attachments, and send or void invoices directly from code using SQL stored procedures.
- Connect securely using OAuth and modern cryptography, including TLS 1.2, SHA-256, and ECC.
Many users access live QuickBooks Online data from preferred analytics tools like Power BI and Excel, directly from databases with federated access, and use CData solutions to easily integrate QuickBooks Online data with automated workflows for business-to-business communications.

Getting Started
Connect to QuickBooks Online in Connect AI
CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.
- Log into Connect AI, click Sources, and then click Add Connection
- Select "QuickBooks Online" from the Add Connection panel
-
QuickBooks Online uses OAuth to authenticate. Click "Sign in" to authenticate with QuickBooks Online.
- 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.
- Click the Gear icon () at the top right of the Connect AI app to open the Settings page.
- On the Settings page, go to the Access Tokens section and click Create PAT.
- Give the PAT a name and click Create.

- The PAT is only visible at creation, so copy it and store it securely.
Install the SDK
Install the SDK from PyPI with pip:
pip install cdata-connect-ai
Connect and Run Your First Query
Connect with your account email and PAT, then query sys_tables to discover every table available across your connected sources. Identifiers in Connect AI are three-part: <Connection>.<Schema>.<Table>, where the connection name defaults to the source name (for example, QuickBooksOnline1).
import cdata_connect_ai
conn = cdata_connect_ai.connect(
username="[email protected]",
password="<your_pat>",
)
cur = conn.cursor()
# Discover what's available across your connected sources
cur.execute("SELECT CatalogName, SchemaName, TableName FROM sys_tables LIMIT 25")
for row in cur.fetchall():
print(row)
Pick any table from the results and query it directly:
cur.execute(
"SELECT DisplayName, Balance "
"FROM [QuickBooksOnline1].[QuickBooksOnline].[Customers] "
"LIMIT 10"
)
for row in cur.fetchall():
print(row)
Write Back to QuickBooks Online
When the data source and your connection permissions allow it, the same cursor runs INSERT, UPDATE, and DELETE statements. Bind values with pyformat (%(name)s) parameters, exactly as you would for a filtered read, and check cursor.rowcount for the number of affected rows.
# Insert a new record
cur.execute(
"INSERT INTO [QuickBooksOnline1].[QuickBooksOnline].[Customers] (DisplayName) "
"VALUES (%(newvalue)s)",
{"newvalue": "Example value"},
)
print(f"Rows inserted: {cur.rowcount}")
# Update existing records
cur.execute(
"UPDATE [QuickBooksOnline1].[QuickBooksOnline].[Customers] "
"SET Balance = %(newvalue)s "
"WHERE FullyQualifiedName = 'Cook, Brian'",
{"newvalue": "Updated value"},
)
print(f"Rows updated: {cur.rowcount}")
conn.close()
Note: Even for writable sources, a read-only PAT or connection permission will reject write operations. The same parameterized pattern also covers DELETE statements and stored procedures through cursor.callproc().
That is the entire workflow: one package, a PAT, and standard DB-API calls. Because the SDK returns a normal DB-API connection, it drops straight into the rest of the Python data ecosystem. From here you can load QuickBooks Online data into pandas, build ETL pipelines with petl, or power a Dash web app, all using this same connection.
