Getting Started with the CData Connect AI Python SDK for PayPal

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 PayPal data with standard Python database code. Because Connect AI provides the connectivity: you install one package, authenticate with a Personal Access Token, and query PayPal (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 PayPal in Connect AI, generating a Personal Access Token, installing the SDK, and reading (and, where supported, writing) live PayPal data.

Prerequisites

• An account in CData Connect AI
• Python 3.8 or higher
• An active PayPal account with valid credentials

Connect to PayPal 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 "PayPal" from the Add Connection panel

3. Enter the necessary authentication properties to connect to PayPal.

   The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

   • The REST API uses the OAuth standard. To authenticate to the REST API, set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
   • The Classic API requires Signature API credentials. To authenticate to the Classic API, obtain an API username, password, and signature.

   See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

   To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

   For testing purposes you can set UseSandbox to true and use sandbox credentials.

   
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 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, PayPal1).

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 Date, GrossAmount "
    "FROM [PayPal1].[PayPal].[Transactions] "
    "LIMIT 10"
)

for row in cur.fetchall():
    print(row)

PayPal is a read-only source in Connect AI, so the SDK supports queries but not INSERT, UPDATE, or DELETE. Close the connection when you are finished:

conn.close()

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 PayPal data into pandas, build ETL pipelines with petl, or power a Dash web app, all using this same connection.
