Credentials for accessing Google's OAuth2 servers are required in order to authenticate and authorize Google Ads users. These credentials identify your app to Google, and allow you to generate OAuth tokens for managing Google Ads users. Access to Google OAuth2 credentials is managed from the Google API Console.
Create a project
Go to the Google API Console. Click Create project, enter a name, and click Create.
Enable the Google Ads API in your project
To enable the Google Ads API for your project, do the following:
Open the API Library in the Google API Console. If prompted, select your project or create a new one. The API Library lists all available APIs, grouped by product family and popularity.
Use search to find the Google Ads API if it isn't visible in the list.
Select the Google Ads API, then click the Enable button.
Choose an app type
There are two app type options for the Google Ads API:
- Installed application (recommended)
- Web application
Check the table below to determine which type is most appropriate for the app you want to build:
|Choose this app type||If ...|
|Installed app (recommended)||
Create a client ID and client secret
Once you've determined your app type, follow the instructions below to generate the OAuth2 client ID and client secret:
Open the Credentials page. Select a previously created project or create a new one.
On the Credentials screen, click CREATE CREDENTIALS, then select OAuth client ID.
If you hadn't configured an OAuth consent screen for this project previously, you'll be directed to do so now. Click CONFIGURE CONSENT SCREEN.
Select the user type and click CREATE.
Fill out the initial form. You can edit this later if needed. Click Save when done.
Navigate back to Credentials > CREATE CREDENTIALS > OAuth client ID to continue.
Select Desktop app as the app type unless you're building for one of the other listed app types.
Give it a name, then click Create.
On the confirmation page, copy Your Client ID and Your Client Secret to your clipboard, as you will need them when you configure your client library. You can also return to the credentials page later to retrieve these details.
