In the Google Cloud console, go to APIs \\& services for your project. [Go to APIs \\& Services](https://console.cloud.google.com/apis)\n\n2. On the **Library** page, click **Private APIs**. If you don't see the API listed, that means you haven't been granted access to enable the API.\n3. Click the API you want to enable. If you need help finding the API, use the search field.\n4. In the page that displays information about the API, click **Enable**.\n\n### gcloud\n\n1. Enter the following to display the project IDs for your\n Google Cloud projects:\n\n gcloud projects list\n\n2. Using the applicable project ID from the previous step, set the default\n project to the one in which you want to enable the API:\n\n ```\n gcloud config set project YOUR_PROJECT_ID\n ```\n3. Get a list of services that you can enable in your project:\n\n gcloud services list --available\n\n If you don't see the API listed, that means you haven't been granted\n access to enable the API.\n4. Using the applicable service name from the previous step, enable the\n service:\n\n ```\n gcloud services enable SERVICE_NAME\n ```\n\nFor more information on the preceding commands, see the\n[`gcloud` reference](/sdk/gcloud/reference)."]]
