Configure a Client Library for OAuth in the Google Ads API
Stay organized with collections
Save and categorize content based on your preferences.
After you've obtained the configuration
requirements, you're ready to set up a
client library to handle Google Ads API calls. Since each client library is configured
differently, follow the linked instructions for your particular programming
language.
Verify your configuration
When you've completed setting up OAuth, make a call to the Google Ads API using one of
the provided code examples in the client library. Choose a simple example, like
GetCampaigns, to verify your setup.
If you encounter issues, consult the troubleshooting
guide for tips on debugging common
issues.
