How to Build an ETL App for Wrike 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 Wrike-connected applications and pipelines for extracting, transforming, and loading Wrike data. This article shows how to connect to Wrike with the CData Python Connector and use petl and pandas to extract, transform, and load Wrike data.
With built-in, optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Wrike data in Python. When you issue complex SQL queries from Wrike, the driver pushes supported SQL operations, like filters and aggregations, directly to Wrike and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to Wrike Data
Connecting to Wrike 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 Wrike Profile on disk (e.g. C:\profiles\Wrike.apip). Next, set the ProfileSettings connection property to the connection string for Wrike (see below).
Wrike API Profile Settings
Obtain a permanent API token from the Wrike App Console by clicking Obtain Token.
After installing the CData Wrike Connector, follow the procedure below to install the other required modules and start accessing Wrike 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 Wrike 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 Wrike Connector to create a connection for working with Wrike data.
cnxn = mod.connect("Profile=C:\profiles\Wrike.apip;ProfileSettings='APIKey=your_api_key';")
Create a SQL Statement to Query Wrike
Use SQL to create a statement for querying Wrike. In this article, we read data from the Account entity.
sql = "SELECT Id, Name FROM Account WHERE SubscriptionType = 'Pro'"
Extract, Transform, and Load the Wrike Data
With the query results stored in a DataFrame, we can use petl to extract, transform, and load the Wrike data. In this example, we extract Wrike data, sort the data by the Name column, and load the data into a CSV file.
Loading Wrike Data into a CSV File
table1 = etl.fromdb(cnxn,sql) table2 = etl.sort(table1,'Name') etl.tocsv(table2,'account_data.csv')
With the CData API Driver for Python, you can work with Wrike data just like you would with any database, including direct access to data in ETL packages like petl.
