Setting up API keys

If your client application does not use OAuth 2.0, then it must include an API key when it calls an API that's enabled within a Google Cloud Platform project. The application passes this key into all API requests as a key=API_key parameter.

To create your application's API key:

  1. Go to the API Console.
  2. From the projects list, select a project or create a new one.
  3. If the APIs & services page isn't already open, open the left side menu and select APIs & services.
  4. On the left, choose Credentials.
  5. Click Create credentials and then select API key.

Note: In addition to reading the instructions on this page, be sure to read Best practices for securely using API keys.
