API Reference (API Version 2015-12-08)

RequestCertificate

Requests an ACM certificate for use with other AWS services. To request an ACM certificate, you must specify a fully qualified domain name (FQDN) in the DomainName parameter. You can also specify additional FQDNs in the SubjectAlternativeNames parameter.

If you are requesting a private certificate, domain validation is not required. If you are requesting a public certificate, each domain name that you specify must be validated to verify that you own or control the domain. You can use DNS validation or email validation. We recommend that you use DNS validation. ACM issues public certificates after receiving approval from the domain owner.

Request Syntax

{ "CertificateAuthorityArn": "string", "DomainName": "string", "DomainValidationOptions": [ { "DomainName": "string", "ValidationDomain": "string" } ], "IdempotencyToken": "string", "Options": { "CertificateTransparencyLoggingPreference": "string" }, "SubjectAlternativeNames": [ "string" ], "ValidationMethod": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

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

DomainName

Fully qualified domain name (FQDN), such as www.example.com, that you want to secure with an ACM certificate. Use an asterisk (*) to create a wildcard certificate that protects several sites in the same domain. For example, *.example.com protects www.example.com, site.example.com, and images.example.com.

The first domain name you enter cannot exceed 63 octets, including periods. Each subsequent Subject Alternative Name (SAN), however, can be up to 253 octets in length.

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

CertificateAuthorityArn

The Amazon Resource Name (ARN) of the private certificate authority (CA) that will be used to issue the certificate. If you do not provide an ARN and you are trying to request a private certificate, ACM will attempt to issue a public certificate. For more information about private CAs, see the AWS Certificate Manager Private Certificate Authority (PCA) user guide. The ARN must have the following form:

arn:aws:acm-pca:region:account:certificate-authority/12345678-1234-1234-1234-123456789012

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: arn:[\w+=/,.@-]+:[\w+=/,.@-]+:[\w+=/,.@-]*:[0-9]+:[\w+=,.@-]+(/[\w+=,.@-]+)*

Required: No

DomainValidationOptions

The domain name that you want ACM to use to send you emails so that you can validate domain ownership.

Type: Array of DomainValidationOption objects

Array Members: Minimum number of 1 item. Maximum number of 100 items.

Required: No

IdempotencyToken

Customer chosen string that can be used to distinguish between calls to RequestCertificate. Idempotency tokens time out after one hour. Therefore, if you call RequestCertificate multiple times with the same idempotency token within one hour, ACM recognizes that you are requesting only one certificate and will issue only one. If you change the idempotency token for each call, ACM recognizes that you are requesting multiple certificates.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 32.

Pattern: \w+

Required: No

Options

Currently, you can use this parameter to specify whether to add the certificate to a certificate transparency log. Certificate transparency makes it possible to detect SSL/TLS certificates that have been mistakenly or maliciously issued. Certificates that have not been logged typically produce an error message in a browser. For more information, see Opting Out of Certificate Transparency Logging.

Type: CertificateOptions object

Required: No

SubjectAlternativeNames

Additional FQDNs to be included in the Subject Alternative Name extension of the ACM certificate. For example, add the name www.example.net to a certificate for which the DomainName field is www.example.com if users can reach your site by using either name. The maximum number of domain names that you can add to an ACM certificate is 100. However, the initial limit is 10 domain names. If you need more than 10 names, you must request a limit increase. For more information, see Limits.

The maximum length of a SAN DNS name is 253 octets. The name is made up of multiple labels separated by periods. No label can be longer than 63 octets. Consider the following examples:

  • (63 octets).(63 octets).(63 octets).(61 octets) is legal because the total length is 253 octets (63+1+63+1+63+1+61) and no label exceeds 63 octets.

  • (64 octets).(63 octets).(63 octets).(61 octets) is not legal because the total length exceeds 253 octets (64+1+63+1+63+1+61) and the first label exceeds 63 octets.

  • (63 octets).(63 octets).(63 octets).(62 octets) is not legal because the total length of the DNS name (63+1+63+1+63+1+62) exceeds 253 octets.

Type: Array of strings

Array Members: Minimum number of 1 item. Maximum number of 100 items.

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: No

ValidationMethod

The method you want to use if you are requesting a public certificate to validate that you own or control domain. You can validate with DNS or validate with email. We recommend that you use DNS validation.

Type: String

Valid Values: EMAIL | DNS

Required: No

Response Syntax

{ "CertificateArn": "string" }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

CertificateArn

String that contains the ARN of the issued certificate. This must be of the form:

arn:aws:acm:us-east-1:123456789012:certificate/12345678-1234-1234-1234-123456789012

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: arn:[\w+=/,.@-]+:[\w+=/,.@-]+:[\w+=/,.@-]*:[0-9]+:[\w+=,.@-]+(/[\w+=,.@-]+)*
