How to Build an ETL App for Sendwithus Data in Python with CData

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData API Driver for Python and the petl framework, you can build Sendwithus-connected applications and pipelines for extracting, transforming, and loading Sendwithus data. This article shows how to connect to Sendwithus with the CData Python Connector and use petl and pandas to extract, transform, and load Sendwithus data.

With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Sendwithus data in Python. When you issue complex SQL queries from Sendwithus, the driver pushes supported SQL operations, like filters and aggregations, directly to Sendwithus and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Sendwithus Data

Connecting to Sendwithus 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.

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

Sendwithus API Profile Settings

Navigate to API Settings in your Sendwithus account and select Create new API Key to generate your authentication credential.

After installing the CData Sendwithus Connector, follow the procedure below to install the other required modules and start accessing Sendwithus through Python objects.

Install Required Modules

Use the pip utility to install the required modules and frameworks:

pip install petl
pip install pandas

Build an ETL App for Sendwithus Data in Python

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

First, be sure to import the modules (including the CData Connector) with the following:

import petl as etl
import pandas as pd
import cdata.api as mod

You can now connect with a connection string. Use the connect function for the CData Sendwithus Connector to create a connection for working with Sendwithus data.

cnxn = mod.connect("Profile=C:\profiles\Sendwithus.apip;ProfileSettings='APIKey=your_api_key';")

Create a SQL Statement to Query Sendwithus

Use SQL to create a statement for querying Sendwithus. In this article, we read data from the CustomerLogs entity.

sql = "SELECT Id, Created FROM CustomerLogs WHERE Status = 'sent'"

Extract, Transform, and Load the Sendwithus Data

With the query results stored in a DataFrame, we can use petl to extract, transform, and load the Sendwithus data. In this example, we extract Sendwithus data, sort the data by the Created column, and load the data into a CSV file.

Loading Sendwithus Data into a CSV File

table1 = etl.fromdb(cnxn,sql)

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

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

With the CData API Driver for Python, you can work with Sendwithus data just like you would with any database, including direct access to data in ETL packages like petl.
