**Note**  
In the following list, the required parameters are described first.

 ** DomainName **   <a name="ACM-Type-DomainValidation-DomainName"></a>
A fully qualified domain name (FQDN) in the certificate. For example, `www.example.com` or `example.com`.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 253.  
Pattern: `(\*\.)?(((?!-)[A-Za-z0-9-]{0,62}[A-Za-z0-9])\.)+((?!-)[A-Za-z0-9-]{1,62}[A-Za-z0-9])`   
Required: Yes

 ** HttpRedirect **   <a name="ACM-Type-DomainValidation-HttpRedirect"></a>
Contains information for HTTP-based domain validation of certificates requested through Amazon CloudFront and issued by ACM. This field exists only when the certificate type is `AMAZON_ISSUED` and the validation method is `HTTP`.  
Type: [HttpRedirect](API_HttpRedirect.md) object  
Required: No

 ** ResourceRecord **   <a name="ACM-Type-DomainValidation-ResourceRecord"></a>
Contains the CNAME record that you add to your DNS database for domain validation. For more information, see [Use DNS to Validate Domain Ownership](https://docs.aws.amazon.com/acm/latest/userguide/gs-acm-validate-dns.html).  
The CNAME information that you need does not include the name of your domain. If you include your domain name in the DNS database CNAME record, validation fails. For example, if the name is `_a79865eb4cd1a6ab990a45779b4e0b96.yourdomain.com`, only `_a79865eb4cd1a6ab990a45779b4e0b96` must be used.
