  +If you have multiple hosted zones for a given domain, you can choose a specific one to be used when configuring the domain.
  +
  +```js {6-9}
  +import { HostedZone } from "@aws-cdk/aws-route53";
  +
  +new Api(this, "Api", {
  + customDomain: {
  + domainName: "api.domain.com",
  + hostedZone: HostedZone.fromHostedZoneAttributes(this, "MyZone", {
  + hostedZoneId,
  + zoneName,
  + }),
  + },
  + routes: {
  + "GET /notes": "src/list.main",
  + },
  +});
  +```
