What is Google API Credentials?
The Credentials page manages API keys and OAuth client configurations for a selected Cloud project. These credential types serve different purposes. The correct choice depends on the API and whether the application needs to act with user authorization.
Open the right destination
Use the account associated with the work you want to open. If Google selects another account automatically, switch using its profile menu. Complete the destination’s identity checks and any required account setup.
Before you start
Your first useful task
- Confirm the project associated with the integration.
- Identify the credential type required by the service’s documentation.
- Review restrictions or OAuth redirect settings for the environment you are configuring.
A practical way to use Google API Credentials
Use clear names that identify the application and environment. Keep secret material out of public repositories and client code where it does not belong. Record which deployed service uses a credential before replacing it.
Troubleshooting
OAuth sign-in fails with a redirect mismatch.
Compare the application’s actual callback URL with the registered redirect URI, including scheme, path, and port. Also confirm that the app uses the intended OAuth client.
Common questions
Can an API key replace OAuth for every Google API?
No. Authentication and authorization requirements vary by API and operation. Follow the service’s documented credential model.
Why does the direct link still ask me to sign in?
The shortcut reaches the application entry point. It cannot carry your Google session between browsers, grant permissions, or bypass verification. Follow the sign-in instructions on the destination service.
Do I need an account with The Login Link?
No. This directory does not require registration. The Open button takes you to the service; any account credentials are entered there.
