Querying CA Details

Function

This API is used to query details about a CA.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Action	Access Level	Resource Type (*: required)	Condition Key	Alias	Dependencies
pca:ca:get	Read	ca *	g:ResourceTag/<tag-key>	-	-
pca:ca:get	Read	-	g:EnterpriseProjectId	-	-

URI

GET /v1/private-certificate-authorities/{ca_id}

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
ca_id	Yes	String	ID of the CA certificate Minimum: 36 Maximum: 36

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. For details, see [Obtaining a User Token] (https://support.huaweicloud.com/intl/en-us/api-iam/iam_30_0001.html).

Response Parameters

type	String	The CA type can be: ROOT: root CA SUBORDINATE: subordinate CA
status	String	CA certificate status: PENDING: The CA certificate is not activated. The CA cannot issue certificates. ACTIVED: The CA certificate has been activated. You can use the CA to issue certificates. DISABLED: The CA certificate is disabled. The CA cannot issue certificates. DELETED: The CA certificate is to be deleted as scheduled. In this state, the CA cannot issue certificates. EXPIRED: The CA certificate has expired. An expired CA cannot issue certificates.
path_length	Integer	CA path length. NOTE: Note: The path length of the generated root CA certificate is not limited, but this field is set to 7 in the database. The path length of a subordinate CA is specified by you when you create subordinate CA. The default value is 0. Minimum: 0 Maximum: 6
