rules property

Define system parameters.

The parameters defined here will override the default parameters implemented by the system. If this field is missing from the service config, default system parameters will be used. Default system parameters and names is implementation-dependent.

Example: define api key for all methods

system_parameters
  rules:
    - selector: "*"
      parameters:
        - name: api_key
          url_query_parameter: api_key

Example: define 2 api key names for a specific method.

system_parameters
  rules:
    - selector: "/ListShelves"
      parameters:
        - name: api_key
          http_header: Api-Key1
        - name: api_key
          http_header: Api-Key2

NOTE: All service configuration rules follow "last one wins" order.
