GAPandas is a Python package for accessing Google Analytics API data using Pandas for use in models, reports or visualisations

GAPandas

GAPandas is a Python package that lets you query the Google Analytics reporting API and return results in Pandas DataFrames so they can be easily analysed, reported or plotted in Python applications. It is a simple wrapper to Google's official API which is designed to reduce code and simplify development, especially from Jupyter Notebook environments.

Setup

GAPandas is easy to setup. First, you need to obtain a client_secrets.json keyfile from Google Analytics in order to authenticate. Google's documentation explains how to do this. Once you have created a client_secrets.json file, download it and store it on your machine and note the path to the file.

Basic example

To make a query, authenticate by running connect.get_service() passing it the path to your client_secrets.json keyfile.

from gapandas import connect, query

service = connect.get_service('path/to/client_secrets.json')

Now you have a connection, construct an API query to pass to the API. This "payload" must include a start-date and end-date, some metrics and some dimensions stored in a Python dictionary.

The queries can sometimes be fiddly to write. I recommend using the Google Analytics Query Explorer to construct a valid API query or creating a prototype in Google Sheets. In the below example, we'll fetch sessions, pageviews and bounces by date for the past 30 days.

payload = {
    'start_date': '30daysAgo',
    'end_date': 'today',
    'metrics': 'ga:sessions, ga:pageviews, ga:bounces',
    'dimensions': 'ga:date'
}

Now you can then use the query.run_query() function to pass your payload to the API, along with the service object and your Google Analytics view ID.

results = query.run_query(service, '123456789', payload)
print(results)

By default, this will return a Pandas DataFrame containing your query results. However, by passing the optional value of 'raw' at the end of the function you can also return the raw data object. The query method also provides some other features to extract data from the raw object.

results = query.run_query(service, '123456789', payload, 'raw')

You can run multiple queries in succession and use the Pandas merge() function to connect these together. Pandas also makes it very easy to write the data to a file, such as a CSV or Excel document or write it to a database. You can use the data in reports, visualisations or machine learning models with very little code.
