InactivateDeviceCertificate - ApsaraMQ for MQTT - Alibaba Cloud Documentation Center

A device certificate is a digital certificate that a root Certificate Authority (CA) issues to a client device. The service uses this certificate to authenticate the client during connection. If authentication is successful, the service and the client can communicate securely using the encryption key in the certificate. If authentication fails, the service denies the client's connection. Should you need to temporarily disable a device certificate, you can call this operation to inactivate it, setting its status to inactive.

Operation description

Only Platinum Edition instances support the InactivateDeviceCertificate operation.
The request frequency for a single user is limited to 500 calls per second. For special requirements, join the DingTalk group (ID: 35228338) to contact ApsaraMQ for MQTT technical support.

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.
