Enterprise Knowledge Graph client libraries

This page shows how to get started with the Cloud Client Libraries for the Enterprise Knowledge Graph API. Read more about the client libraries for Cloud APIs, including the older Google API Client Libraries, in Client Libraries Explained.

Install the client library


For more information, see Setting Up a Python Development Environment.

pip install --upgrade google-cloud-enterpriseknowledgegraph

Set up authentication

When you use client libraries, you use Application Default Credentials (ADC) to authenticate. For information about setting up ADC, see Provide credentials for Application Default Credentials. For information about using ADC with client libraries, see Authenticate using client libraries.

Use the client library

The following example shows how to use the client library.


For more information, see the Enterprise Knowledge Graph Python API reference documentation.

To authenticate to Enterprise Knowledge Graph, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.
