This is the ACM Private CA API Reference. It provides descriptions, syntax, and usage examples for each of the actions and data types involved in creating and managing private certificate authorities (CA) for your organization.
The documentation for each action shows the Query API request parameters and the XML response. Alternatively, you can use one of the AWS SDKs to access an API that's tailored to the programming language or platform that you're using. For more information, see AWS SDKs.
Each ACM Private CA API action has a throttling limit which determines the number of times the action can be called per second. For more information, see API Rate Limits in ACM Private CA in the ACM Private CA user guide.

CreateCertificateAuthorityResult createCertificateAuthority(CreateCertificateAuthorityRequest createCertificateAuthorityRequest)
Creates a root or subordinate private certificate authority (CA). You must specify the CA configuration, the certificate revocation list (CRL) configuration, the CA type, and an optional idempotency token to avoid accidental creation of multiple CAs. The CA configuration specifies the name of the algorithm and key size to be used to create the CA private key, the type of signing algorithm that the CA uses, and X.500 subject information. The CRL configuration specifies the CRL expiration period in days (the validity period of the CRL), the Amazon S3 bucket that will contain the CRL, and a CNAME alias for the S3 bucket that is included in certificates issued by the CA. If successful, this action returns the Amazon Resource Name (ARN) of the CA.
createCertificateAuthorityRequest - InvalidArgsException - One or more of the specified arguments was not valid.InvalidPolicyException - The S3 bucket policy is not valid. The policy must give ACM Private CA rights to read from and write to
the bucket and find the bucket location.InvalidTagException - The tag associated with the CA is not valid. The invalid argument is contained in the message field.LimitExceededException - An ACM Private CA limit has been exceeded. See the exception message returned to determine the limit that
was exceeded.CreateCertificateAuthorityAuditReportResult createCertificateAuthorityAuditReport(CreateCertificateAuthorityAuditReportRequest createCertificateAuthorityAuditReportRequest)
Creates an audit report that lists every time that your CA private key is used. The report is saved in the Amazon S3 bucket that you specify on input. The IssueCertificate and RevokeCertificate actions use the private key.
createCertificateAuthorityAuditReportRequest - RequestInProgressException - Your request is already in progress.RequestFailedException - The request has failed for an unspecified reason.ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidArgsException - One or more of the specified arguments was not valid.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.CreatePermissionResult createPermission(CreatePermissionRequest createPermissionRequest)
Assigns permissions from a private CA to a designated AWS service. Services are specified by their service principals and can be given permission to create and retrieve certificates on a private CA. Services can also be given permission to list the active permissions that the private CA has granted. For ACM to automatically renew your private CA's certificates, you must assign all possible permissions from the CA to the ACM service principal.
At this time, you can only assign permissions to ACM (acm.amazonaws.com). Permissions can be revoked
with the DeletePermission action and listed with the ListPermissions action.
createPermissionRequest - ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.PermissionAlreadyExistsException - The designated permission has already been given to the user.LimitExceededException - An ACM Private CA limit has been exceeded. See the exception message returned to determine the limit that
was exceeded.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.RequestFailedException - The request has failed for an unspecified reason.DeleteCertificateAuthorityResult deleteCertificateAuthority(DeleteCertificateAuthorityRequest deleteCertificateAuthorityRequest)
Deletes a private certificate authority (CA). You must provide the Amazon Resource Name (ARN) of the private CA that you want to delete. You can find the ARN by calling the ListCertificateAuthorities action.
Deleting a CA will invalidate other CAs and certificates below it in your CA hierarchy.
Before you can delete a CA that you have created and activated, you must disable it. To do this, call the
UpdateCertificateAuthority action and set the CertificateAuthorityStatus parameter to
DISABLED.
Additionally, you can delete a CA if you are waiting for it to be created (that is, the status of the CA is
CREATING). You can also delete it if the CA has been created but you haven't yet imported the signed
certificate into ACM Private CA (that is, the status of the CA is PENDING_CERTIFICATE).
When you successfully call DeleteCertificateAuthority, the CA's status changes to DELETED.
However, the CA won't be permanently deleted until the restoration period has passed. By default, if you do not
set the PermanentDeletionTimeInDays parameter, the CA remains restorable for 30 days. You can set
the parameter from 7 to 30 days. The DescribeCertificateAuthority action returns the time remaining in the
restoration window of a private CA in the DELETED state. To restore an eligible CA, call the
RestoreCertificateAuthority action.
deleteCertificateAuthorityRequest - ConcurrentModificationException - A previous update to your private CA is still ongoing.ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.DeletePermissionResult deletePermission(DeletePermissionRequest deletePermissionRequest)

deletePermissionRequest - ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.RequestFailedException - The request has failed for an unspecified reason.DescribeCertificateAuthorityResult describeCertificateAuthority(DescribeCertificateAuthorityRequest describeCertificateAuthorityRequest)
Lists information about your private certificate authority (CA). You specify the private CA on input by its ARN (Amazon Resource Name). The output contains the status of your CA. This can be any of the following:
CREATING - ACM Private CA is creating your private certificate authority.
PENDING_CERTIFICATE - The certificate is pending. You must use your ACM Private CA-hosted or
on-premises root or subordinate CA to sign your private CA CSR and then import it into PCA.
ACTIVE - Your private CA is active.
DISABLED - Your private CA has been disabled.
EXPIRED - Your private CA certificate has expired.
FAILED - Your private CA has failed. Your CA can fail because of problems such a network outage or
backend AWS failure or other errors. A failed CA can never return to the pending state. You must create a new CA.
DELETED - Your private CA is within the restoration period, after which it is permanently deleted.
The length of time remaining in the CA's restoration period is also included in this action's output.
describeCertificateAuthorityRequest - ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.DescribeCertificateAuthorityAuditReportResult describeCertificateAuthorityAuditReport(DescribeCertificateAuthorityAuditReportRequest describeCertificateAuthorityAuditReportRequest)
Lists information about a specific audit report created by calling the CreateCertificateAuthorityAuditReport action. Audit information is created every time the certificate authority (CA) private key is used. The private key is used when you call the IssueCertificate action or the RevokeCertificate action.
describeCertificateAuthorityAuditReportRequest - ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidArgsException - One or more of the specified arguments was not valid.GetCertificateResult getCertificate(GetCertificateRequest getCertificateRequest)
Retrieves a certificate from your private CA. The ARN of the certificate is returned when you call the IssueCertificate action. You must specify both the ARN of your private CA and the ARN of the issued certificate when calling the GetCertificate action. You can retrieve the certificate if it is in the ISSUED state. You can call the CreateCertificateAuthorityAuditReport action to create a report that contains information about all of the certificates issued and revoked by your private CA.
getCertificateRequest - RequestInProgressException - Your request is already in progress.RequestFailedException - The request has failed for an unspecified reason.ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.GetCertificateAuthorityCertificateResult getCertificateAuthorityCertificate(GetCertificateAuthorityCertificateRequest getCertificateAuthorityCertificateRequest)

Retrieves the certificate signing request (CSR) for your private certificate authority (CA). The CSR is created when you call the CreateCertificateAuthority action. Sign the CSR with your ACM Private CA-hosted or on-premises root or subordinate CA. Then import the signed certificate back into ACM Private CA by calling the ImportCertificateAuthorityCertificate action. The CSR is returned as a base64 PEM-encoded string.
getCertificateAuthorityCsrRequest - RequestInProgressException - Your request is already in progress.RequestFailedException - The request has failed for an unspecified reason.ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.ImportCertificateAuthorityCertificateResult importCertificateAuthorityCertificate(ImportCertificateAuthorityCertificateRequest importCertificateAuthorityCertificateRequest)
Imports a signed private CA certificate into ACM Private CA. This action is used when you are using a chain of trust whose root is located outside ACM Private CA. Before you can call this action, the following preparations must in place:
In ACM Private CA, call the CreateCertificateAuthority action to create the private CA that that you plan to back with the imported certificate.
Call the GetCertificateAuthorityCsr action to generate a certificate signing request (CSR).
Sign the CSR using a root or intermediate CA hosted either by an on-premises PKI hierarchy or a commercial CA..
Create a certificate chain and copy the signed certificate and the certificate chain to your working directory.
The following requirements apply when you import a CA certificate.
You cannot import a non-self-signed certificate for use as a root CA.
You cannot import a self-signed certificate for use as a subordinate CA.
Your certificate chain must not include the private CA certificate that you are importing.
Your ACM Private CA-hosted or on-premises CA certificate must be the last certificate in your chain. The subordinate certificate, if any, that your root CA signed must be next to last. The subordinate certificate signed by the preceding subordinate CA must come next, and so on until your chain is built.
The chain must be PEM-encoded.

listTagsRequest - ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.RestoreCertificateAuthorityResult restoreCertificateAuthority(RestoreCertificateAuthorityRequest restoreCertificateAuthorityRequest)
Restores a certificate authority (CA) that is in the DELETED state. You can restore a CA during the
period that you defined in the PermanentDeletionTimeInDays parameter of the
DeleteCertificateAuthority action. Currently, you can specify 7 to 30 days. If you did not specify a
PermanentDeletionTimeInDays value, by default you can restore the CA at any time in a 30 day period. You
can check the time remaining in the restoration period of a private CA in the DELETED state by
calling the DescribeCertificateAuthority or ListCertificateAuthorities actions. The status of a
restored CA is set to its pre-deletion status when the RestoreCertificateAuthority action returns. To
change its status to ACTIVE, call the UpdateCertificateAuthority action. If the private CA
was in the PENDING_CERTIFICATE state at deletion, you must use the
ImportCertificateAuthorityCertificate action to import a certificate authority into the private CA before
it can be activated. You cannot restore a CA after the restoration period has ended.

Revokes a certificate that was issued inside ACM Private CA. If you enable a certificate revocation list (CRL) when you create or update your private CA, information about the revoked certificates will be included in the CRL. ACM Private CA writes the CRL to an S3 bucket that you specify. For more information about revocation, see the CrlConfiguration structure. ACM Private CA also writes revocation information to the audit report. For more information, see CreateCertificateAuthorityAuditReport.
You cannot revoke a root CA self-signed certificate.

Adds one or more tags to your private CA. Tags are labels that you can use to identify and organize your AWS resources. Each tag consists of a key and an optional value. You specify the private CA on input by its Amazon Resource Name (ARN). You specify the tag by using a key-value pair. You can apply a tag to just one private CA if you want to identify a specific characteristic of that CA, or you can apply the same tag to multiple private CAs if you want to filter for a common relationship among those CAs. To remove one or more tags, use the UntagCertificateAuthority action. Call the ListTags action to see what tags are associated with your CA.
tagCertificateAuthorityRequest - ResourceNotFoundException - A resource such as a private CA, S3 bucket, certificate, or audit report cannot be found.InvalidArnException - The requested Amazon Resource Name (ARN) does not refer to an existing resource.InvalidStateException - The private CA is in a state during which a report or certificate cannot be generated.InvalidTagException - The tag associated with the CA is not valid.
