For more information on the\ndifferences between public and private APIs and services, see\n[Public and Private Services](/service-usage/docs/public-vs-private).\n\nFor most operational use cases, the simplest way to enable and disable services\nis to use the Google Cloud console. If you need to create scripts, you can also use the\nGoogle Cloud CLI. If you need to program against the\nService Usage API, we recommend that you use one of our provided\n[client libraries](/service-usage/docs/libraries). To experiment with the API,\nyou can follow the alternative instructions in this guide and use the `curl`\ncommand to test the API without setting up a full application development\nenvironment.\n\nBefore you begin\n----------------\n\nTo enable and disable APIs and services you need:\n\n- A Google Cloud project. To learn how to create a Google Cloud project, see [Creating and Managing Projects](/resource-manager/docs/creating-managing-projects).\n- The correct [Identity and Access Management](/iam) permissions. To learn about the IAM requirements for Service Usage, see [Access Control](/service-usage/docs/access-control).\n- To install the [Google Cloud CLI](/sdk/docs/install).\n- If you want to use the `curl` examples in this guide, make sure you follow the instructions to complete the initial setup in [Getting Started](/service-usage/docs/set-up-development-environment). These steps include defining `gcurl`, which is an authenticated alias for the standard `curl` command, and defining the environment variable `PROJECT_NUMBER`.\n\nEnabling services\n-----------------\n\nEnabling services uses quota from the\n`serviceusage.googleapis.com/mutate_requests` quota metric. The default\navailable quota is 2 queries per second (QPS). \n\n### console\n\nTo enable an API for a project:\n\n1. Go to the Google Cloud console [API Library](https://console.cloud.google.com/project/_/apis/library) page. \n [Go to the API Library page](https://console.cloud.google.com/project/_/apis/library)\n2. Select the Google Cloud project where you want to enable\n an API by performing one of the following:\n\n - Click on a Google Cloud project under **Select a recent project**.\n\n - Use the Google Cloud project browser by performing the following\n steps:\n\n 1. Click **Select project** to open the Google Cloud project browser.\n 2. Find your project and then click on the Google Cloud project name.\n 3. Click **Open** to open the project.\n3. Click the API you want to enable. If you need help finding the API, use\n the **Search for APIs \\& Services** box near the top of the page. A page\n describing the API appears.\n\n4. Click the **Enable** button.\n\n### gcloud\n\nRun the following command to enable the Pub/Sub API service in your\ncurrent project: \n\n```\ngcloud services enable pubsub.googleapis.com\n```\n\nThe command produces output similar to the following: \n\n```\nWaiting for async operation operations/acf.2e2fcfce-8327-4984-9040-a67777082687 to complete...\nOperation finished successfully.\n```\n\nYou can use the following command to get the operation details: \n\n```\ngcloud services operations describe operations/acf.2e2fcfce-8327-4984-9040-a67777082687\n```\n\n### curl\n\nYou can enable a single service using the\n[`services.enable`](/service-usage/docs/reference/rest/v1/services/enable)\nmethod. You can enable between 2 and 20 services in a single operation using\nthe [`services.batchEnable`](/service-usage/docs/reference/rest/v1/services/batchEnable)\nmethod.\n\n### Enable a single service\n\nThe following command enables the Pub/Sub API service on your\nproject: \n\n gcurl -d '{}' \"https://serviceusage.googleapis.com/v1/projects/${PROJECT_NUMBER}/services/pubsub.googleapis.com:enable\"\n\nThe\n[`services.enable`](/service-usage/docs/reference/rest/v1/services/enable)\nmethod returns a\n[Long Running Operation](/service-usage/docs/reference/rest/v1/operations)\nresource, which represents ongoing work on the server. Each operation has\na unique resource name. For example, here is an operation\nwith the name `operations/acf.2e2fcfce-8327-4984-9040-a67777082687`: \n\n {\n \"name\": \"operations/acf.2e2fcfce-8327-4984-9040-a67777082687\"\n }\n\nTo poll the operation status by using the Service Usage\n[`operations.get`](/service-usage/docs/reference/rest/v1/operations/get)\nmethod, pass the name of the operation to the API: \n\n OPERATION_NAME=\"operations/acf.2e2fcfce-8327-4984-9040-a67777082687\"\n gcurl \"https://serviceusage.googleapis.com/v1/${OPERATION_NAME}\"\n\n### Enable multiple services at once\n\nIf you want to enable multiple API services on your project, you can issue\nan enable command for each API service individually, or you can issue one\nbatch enable command and specify multiple APIs. For example, to enable both\nthe Pub/Sub and Dataflow API services on your project: \n\n gcurl -d '{\n \"serviceIds\": [\"pubsub.googleapis.com\", \"dataflow.googleapis.com\"]\n }' \"https://serviceusage.googleapis.com/v1/projects/${PROJECT_NUMBER}/services:batchEnable\"\n\nLike `services.enable`, [`services.batchEnable`](/service-usage/docs/reference/rest/v1/services/batchEnable)\nreturns an operation resource, which you can poll by using its `name`.\n| **Note:** The process for enabling APIs can vary. Some APIs prompt you to accept their Terms of Service before you can enable them. Some APIs are in preview mode and require special signup and whitelisting before you can use them. Other APIs might ask for additional information, such as your organization's contact information and the name of the application you are developing. When more information is requested, it will not be shared outside of Google; it's used to help Google understand how the API is being used and as a secondary contact should we need to contact you regarding your use of the service.\n\nDisabling services\n------------------\n\nDisabling services uses quota from the\n`serviceusage.googleapis.com/mutate_requests` quota metric. The default\navailable quota is 2 queries per second (QPS).\n\nYou can disable an API for a project at any time, although any pending fees will\nstill be charged to your account and you'll be charged for any billable API use\nin your projects. For more information, see\n[APIs and Billing](https://support.google.com/cloud/answer/6158867).\n\nMany services like Cloud Storage and BigQuery charge to store data. Disabling a\nservice's API access does not delete the underlying data which will continue\nto be billed. If your intent is to discontinue using a service and stop all\nfuture charges, be sure to delete all data associated with the service before\ndisabling the service's API access.\n\nIf you disable the GKE API, any running clusters in the project become suspended. After 30 days, the suspended clusters are deleted. To reinstate your suspended clusters, enable the GKE API. It may take up to 24 hours for the clusters to be reinstated.\n**Note:** In v1 of the API, if you attempt to disable a service that other enabled services depend on, the call will fail. The API call to disable the service will result in an error message. To disable the specified service and all of the services that depend on it, set the `disable_dependent_services` parameter on the [`services.disable`](/service-usage/docs/reference/rest/v1/services/disable) request to `true`. \n\n### console\n\nTo disable an API for a project:\n\n1. Go to the Google Cloud console [API Dashboard](https://console.cloud.google.com/project/_/apis/dashboard) page. \n [Go to the API Dashboard page](https://console.cloud.google.com/project/_/apis/dashboard)\n2. Select the Google Cloud project where you want to disable\n an API by performing one of the following:\n\n - Click on a Google Cloud project under **Select a recent project**.\n\n - Use the Google Cloud project browser by performing the following\n steps:\n\n 1. Click **Select project** to open the Google Cloud project browser.\n 2. Find your project and then click on the Google Cloud project name.\n 3. Click **Open** to open the project.\n3. Click the API you want to disable. If you need help finding the API, use\n the **Search for APIs \\& Services** box near the top of the page. A page\n describing the API appears.\n\n4. Click *stop* **Disable API**.\n\n### gcloud\n\nRun the following command to disable the Pub/Sub API service for\nyour current project: \n\n```\ngcloud services disable pubsub.googleapis.com\n```\n\nThe command produces output similar to the following: \n\n```\nWaiting for async operation operations/acf.e9d0943b-55d9-4ac0-8af4-745e1b8983f8 to complete...\nOperation finished successfully.\n```\n\nYou can use the following command to get the operation details: \n\n```\ngcloud services operations describe operations/acf.e9d0943b-55d9-4ac0-8af4-745e1b8983f8\n```\n\n### curl\n\nThe following command disables the Pub/Sub API service on\nyour project: \n\n gcurl -d '{}' \"https://serviceusage.googleapis.com/v1/projects/${PROJECT_NUMBER}/services/pubsub.googleapis.com:disable\"\n\nLike `services.enable`, [`services.disable`](/service-usage/docs/reference/rest/v1/services/disable)\nreturns an operation resource, which you can poll by using its `name`."]]
