  • If using the KongPlugin object in Kubernetes, the field is plugin.

• service.name or service.id

  string

  The name or ID of the service the plugin targets. Set one of these parameters if adding the plugin to a service through the top-level /plugins endpoint. Not required if using /services/{serviceName|Id}/plugins.

• route.name or route.id

  string

  The name or ID of the route the plugin targets. Set one of these parameters if adding the plugin to a route through the top-level /plugins endpoint. Not required if using /routes/{routeName|Id}/plugins.

• consumer.name or consumer.id

  string

  The name or ID of the consumer the plugin targets. Set one of these parameters if adding the plugin to a consumer through the top-level /plugins endpoint. Not required if using /consumers/{consumerName|Id}/plugins.

• enabled

  boolean default: true

  Whether this plugin will be applied.

• config

  record required
  • remove

    record required
    • json

      array of type string

      List of property names. Remove the property from the JSON body if it is present.

    • headers

      array of type string

      List of headername[:value]. If only headername is given, unset the header field with the given headername. If headername:value is given, unset the header field headername when it has a specific value. If value starts and ends with a / (slash character), then it is considered to be a regular expression. Note that in accordance with RFC 7230 multiple header values with the same header name are allowed if the entire field value for that header field is defined as a comma-separated list or the header field is a Set-Cookie header field.

    • if_status

      array of type string

      List of response status codes or status code ranges to which the transformation will apply. Empty means all response codes.

  • rename

    record required
    • headers

      array of type string

      List of headername1:headername2 pairs. If a header with headername1 exists and headername2 is valid, rename header to headername2.

    • if_status

      array of type string

      List of response status codes or status code ranges to which the transformation will apply. Empty means all response codes.

  • replace

    record required
    • body

      string

      String with which to replace the entire response body.

    • json

      array of type string

      List of property name:value pairs. If and only if the parameter is already present, replace its old value with the new one. Ignored if the parameter is not already present.

    • json_types

      array of type string Must be one of: boolean, number, string

      List of JSON type names. Specify the types of the JSON values returned when replacing JSON properties.

    • headers

      array of type string

      List of headername:value pairs. If and only if the header is already set, replace its old value with the new one. Ignored if the header is not already set.

    • if_status

      array of type string

      List of response status codes or status code ranges to which the transformation will apply. Empty means all response codes.

  • add

    record required
    • json

      array of type string

      List of name:value pairs. If and only if the property is not present, add a new property with the given value to the JSON body. Ignored if the property is already present.

    • json_types

      array of type string Must be one of: boolean, number, string

      List of JSON type names. Specify the types of the JSON values returned when adding a new JSON property.

    • headers

      array of type string

      List of headername:value pairs. If and only if the header is not already set, set a new header with the given value. Ignored if the header is already set.

    • if_status

      array of type string

      List of response status codes or status code ranges to which the transformation will apply. Empty means all response codes.

  • append

    record required
    • json

      array of type string

      List of name:value pairs. If the property is not present in the JSON body, add it with the given value. If it is already present, the two values (old and new) will be aggregated in an array.

    • json_types

      array of type string Must be one of: boolean, number, string

      List of JSON type names. Specify the types of the JSON values returned when appending JSON properties.

    • headers

      array of type string

      List of headername:value pairs. If the header is not set, set it with the given value. If it is already set, a new header with the same name and the new value will be set.

    • if_status

      array of type string

      Set of Lua functions to perform arbitrary transforms in a response JSON body.

    • if_status
