# DisassociateCustomDomain
<a name="API_DisassociateCustomDomain"></a>

**Important**  
 AWS App Runner will no longer be open to new customers starting March 31, 2026. If you would like to use App Runner, sign up prior to that date. Existing customers can continue to use the service as normal. For more information, see [AWS App Runner availability change](https://docs.aws.amazon.com/apprunner/latest/dg/apprunner-availability-change.html).

Disassociate a custom domain name from an AWS App Runner service.

Certificates tracking domain validity are associated with a custom domain and are stored in [AWS Certificate Manager (ACM)](https://docs.aws.amazon.com/acm/latest/userguide). These certificates aren't deleted as part of this action. App Runner delays certificate deletion for 30 days after a domain is disassociated from your service.

### Disassociate a domain name from a service
<a name="API_DisassociateCustomDomain_Example_1"></a>

This example illustrates how to disassociate the domain `example.com` from an App Runner service. The call also disassociates the subdomain `www.example.com` that was associated together with the root domain.

**Note**  
 `CertificateValidationRecords` is an optional field and returns an empty response for `AssociateCustomDomain` APIs.
