How to Build an ETL App for ZohoMarketingHub Data in Python with 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 and the petl framework, you can build ZohoMarketingHub-connected applications and pipelines for extracting, transforming, and loading ZohoMarketingHub data. This article shows how to connect to Connect AI and use petl to extract, transform, and load ZohoMarketingHub data.

The Connect AI Python SDK (cdata-connect-ai) is a DB-API 2.0 (PEP 249) compliant client, so petl can read directly from the SDK connection with etl.fromdb. There is no driver to install per source: connect with a Personal Access Token and build your pipeline.

Connect to ZohoMarketingHub 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 "ZohoMarketingHub" from the Add Connection panel

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

   Start by setting the Profile connection property to the location of the ZohoMarketingHub Profile on disk (e.g. C:\profiles\ZohoMarketingHub.apip). Next, set the ProfileSettings connection property to the connection string for ZohoMarketingHub (see below).

   ZohoMarketingHub API Profile Settings

   Register an OAuth application in the Zoho Developer Console as a server-based application to obtain your Client ID and Client Secret.

   
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 and the petl framework using the pip utility:

pip install cdata-connect-ai
pip install petl

Build an ETL App for ZohoMarketingHub Data in Python

Once the required modules are installed, you are ready to build the ETL app. Code snippets follow, but the full source code is available at the end of the article.

First, import the modules and connect to Connect AI with your account email and PAT:

import petl as etl
import cdata_connect_ai

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

Create a SQL Statement to Query ZohoMarketingHub

Use SQL to create a statement for querying ZohoMarketingHub. In this article, we read data from the CampaignDetails entity. Identifiers are three-part: <Connection>.<Schema>.<Table>, where the connection name defaults to the source name (for example, API1).

sql = (
    "SELECT CampaignKey, CampaignName "
    "FROM [API1].[API].[CampaignDetails] "
    "WHERE CampaignName = 'Q4_Sales_Campaign'"
)

Extract, Transform, and Load the ZohoMarketingHub Data

With a connection and query in hand, use petl to extract, transform, and load the ZohoMarketingHub data. In this example, we extract ZohoMarketingHub data, sort the data by the CampaignName column, and load the data into a CSV file.

table1 = etl.fromdb(conn, sql)

table2 = etl.sort(table1, 'CampaignName')

etl.tocsv(table2, 'campaigndetails_data.csv')

ZohoMarketingHub is a read-only source in Connect AI, so this pipeline can extract and transform ZohoMarketingHub data but not load rows back. Close the connection when the extract is complete:

conn.close()

With the CData Connect AI Python SDK, you can work with ZohoMarketingHub data just like you would with any database, including direct access to data in ETL packages like petl.
