• 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

• enabled

  boolean default: true

  Whether this plugin will be applied.

• config

  record required
  • checked_content_types

    set of type string required default: application/xml

    A list of Content-Type values with payloads that must be validated.

  • allowed_content_types

    set of type string required

    A list of Content-Type values with payloads that are allowed, but aren’t validated. For example, if the API also accepts JSON, you can add "application/json".

  • allow_dtd

    boolean required default: false

    Indicates whether an XML Document Type Definition (DTD) section is allowed.

  • namespace_aware

    boolean required default: true

    If not parsing namespace aware, all prefixes and namespace attributes will be counted as regular attributes and element names, and validated as such.

  • max_depth

    integer required default: 50

    Maximum depth of tags. Child elements such as Text or Comments are not counted as another level.

  • max_children

    integer required default: 100

    Maximum number of children allowed (Element, Text, Comment, ProcessingInstruction, CDATASection). Note: Adjacent text and CDATA sections are counted as one. For example, text-cdata-text-cdata is one child.

  • max_attributes

    integer required default: 100

    Maximum number of attributes allowed on a tag, including default ones. Note: If namespace-aware parsing is disabled, then the namespaces definitions are counted as attributes.

  • max_namespaces

    integer default: 20

    Maximum number of namespaces defined on a tag. This value is required if parsing is namespace-aware.

  • document

    integer required default: 10485760

  • buffer

    integer required default: 1048576

    Maximum size of the unparsed buffer (see below).

  • prefix

    Maximum size of the prefix. This applies to tags and attributes. This value is required if parsing is namespace-aware.

  • namespaceuri

  • attribute

    integer required default: 1048576

    Maximum size of the attribute value.
