This confirmation\nlets you deploy and service APIs on any of its subdomains.\n\nFor example, if domain ownership is established for `example.com`, service names\ncan include subdomains of `example.com` such as `api.example.com` or\n`catalog.api.example.com`.\n\nDeploying an API on a subdomain\n-------------------------------\n\nThe following example deploys the API to the subdomain `first_api.example.com`:\n\n1. Set the `host` field of your OpenAPI document to `first_api.example.com`\n and set the other fields as described in\n [Configuring Cloud Endpoints](/endpoints/docs/openapi/configure-endpoints).\n\n2. [Deploy the Endpoints configuration](/endpoints/docs/openapi/deploy-endpoints-config).\n\n3. [Deploy the API backend](/endpoints/docs/openapi/deploy-api-backend).\n\nNow you can send requests to `first_api.example.com` and view graphs of those\nrequests on the\n[**Endpoints** \\\u003e **Services** page](https://console.cloud.google.com/endpoints).\n\nDeploying your next API\n-----------------------\n\nTo deploy another API, repeat the preceding steps, changing the subdomain\n`first_api.example.com` to the subdomain you are using for the next API."]]
