Certificate Management Service:DescribeClientCertificate

Last Updated:Jan 16, 2026

This operation queries the details of a specific client certificate or server-side certificate using its unique identifier.

Operation description

You can call this operation to query the details of a client certificate or a server-side certificate by its unique identifier. The details include the serial number, subject, content, and status of the certificate.

Before you call this operation, you must create a client certificate or a server-side certificate.

To create a client certificate by calling an API, see the following topics:

To create a server-side certificate by calling an API, see the following topics:

Limits

The queries per second (QPS) limit for this API call is 10 per user. If you exceed this limit, throttling is triggered, which may affect your business. Plan your calls accordingly.

Try it now

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
