    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: DescribeListeners.
    Version Yes String Common Params. The value used for this API: 2018-03-17.
    Region No String Common Params. This parameter is not required for this API.
    LoadBalancerId Yes String CLB instance ID.
    ListenerIds.N No Array of String Array of CLB listener IDs to query (100 IDs at most).
    Protocol No String Type of the listener protocols to be queried. Values: TCP, UDP, HTTP, HTTPS, TCP_SSLandQUIC`.
    Port No Integer Port of the listeners to be queried

    3. Output Parameters

    Parameter Name Type Description
    Listeners Array of Listener Listener list
    TotalCount Integer Total number of listeners (with filters of port, protocol, and listener ID applied).
    Note: This field may return null, indicating that no valid values can be obtained.
