.. py:method:: IoT.Client.update_certificate(**kwargs)

  

  Updates the status of the specified certificate. This operation is idempotent.

   

  Requires permission to access the `UpdateCertificate <https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsiot.html#awsiot-actions-as-permissions>`__ action.

   

  Certificates must be in the ACTIVE state to authenticate devices that use a certificate to connect to IoT.

   

  Within a few minutes of updating a certificate from the ACTIVE state to any other state, IoT disconnects all devices that used that certificate to connect. Devices cannot use a certificate that is not in the ACTIVE state to reconnect.

  **Request Syntax**
  ::

    response = client.update_certificate(
        certificateId='string',
        newStatus='ACTIVE'|'INACTIVE'|'REVOKED'|'PENDING_TRANSFER'|'REGISTER_INACTIVE'|'PENDING_ACTIVATION'
    )
    
  :type certificateId: string
  :param certificateId: **[REQUIRED]** 

    The ID of the certificate. (The last part of the certificate ARN contains the certificate ID.)

    

  
  :type newStatus: string
  :param newStatus: **[REQUIRED]** 

    The new status.

     

    **Note:** Setting the status to PENDING_TRANSFER or PENDING_ACTIVATION will result in an exception being thrown. PENDING_TRANSFER and PENDING_ACTIVATION are statuses used internally by IoT. They are not intended for developer use.

     

    **Note:** The status value REGISTER_INACTIVE is deprecated and should not be used.
