          properties that are not known by the client in the following scenarios:
          1. The OpenAPI document is incomplete, i.e. it does not match the server
             implementation.
          2. The client was generated using an older version of the OpenAPI document
             and the server has been upgraded since then.
          If a schema in the OpenAPI document defines the additionalProperties attribute,
          then all undeclared properties received by the server are injected into the
          additional properties map. In that case, there are undeclared properties, and
          nothing to discard.

        :Example:

        You can set the APIv4 key and secret like:

    conf = gate_api.Configuration(
        key='example_key'
        secret='example_secret'
    )

        The following headers will be added to the HTTP request:
