The following examples provide some typical configurations for enabling the request-transformer-advanced plugin on a service.

Kong Admin API

Konnect API

Kubernetes

Declarative (YAML)

Konnect Terraform

Make the following request:

curl -X POST http://localhost:8001/services/{serviceName|Id}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "request-transformer-advanced",
  "config": {
    "remove": {
      "body": [
        "formparam-toremove",
        "formparam-another-one"
      ]
    },
    "replace": {
      "body": [
        "body-param1:new-value-1",
        "body-param2:new-value-2"
      ]
    },
    "rename": {
      "body": [
        "param-old:param-new",
        "param2-old:param2-new"
      ]
    },
    "add": {
      "querystring": [
        "new-param:some_value",
        "another-param:some_value"
      ]
    }
  }
}
    '

Replace SERVICE_NAME|ID with the id or name of the service that this plugin configuration will target.

Make the following request, substituting your own access token, region, control plane ID, and service ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/services/{serviceId}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"request-transformer-advanced","config":{"remove":{"body":["formparam-toremove","formparam-another-one"]},"replace":{"body":["body-param1:new-value-1","body-param2:new-value-2"]},"rename":{"body":["param-old:param-new","param2-old:param2-new"]},"add":{"querystring":["new-param:some_value","another-param:some_value"]}}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

First, create a KongPlugin resource:

echo "
apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: request-transformer-advanced-example
plugin: request-transformer-advanced
config:
  remove:
    body:
    - formparam-toremove
    - formparam-another-one
  replace:
    body:
    - body-param1:new-value-1
    - body-param2:new-value-2
  rename:
    body:
    - param-old:param-new
    - param2-old:param2-new
  add:
    querystring:
    - new-param:some_value
    - another-param:some_value
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the service as follows:

kubectl annotate service SERVICE_NAME konghq.com/plugins=request-transformer-advanced-example

Replace SERVICE_NAME with the name of the service that this plugin configuration will target. You can see your available ingresses by running kubectl get service.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:
- name: request-transformer-advanced
  service: SERVICE_NAME|ID
  config:
    remove:
      body:
      - formparam-toremove
      - formparam-another-one
    replace:
      body:
      - body-param1:new-value-1
      - body-param2:new-value-2
    rename:
      body:
      - param-old:param-new
      - param2-old:param2-new
    add:
      querystring:
      - new-param:some_value
      - another-param:some_value

Replace SERVICE_NAME|ID with the id or name of the service that this plugin configuration will target.

Prerequisite: Configure your Personal Access Token

terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_request_transformer_advanced" "my_request_transformer_advanced" {
  enabled = true

  config = {
    remove = {
      body = ["formparam-toremove", "formparam-another-one"]
    }
    replace = {
      body = ["body-param1:new-value-1", "body-param2:new-value-2"]
    }
    rename = {
      body = ["param-old:param-new", "param2-old:param2-new"]
    }
    add = {
      querystring = ["new-param:some_value", "another-param:some_value"]
    }
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  service = {
    id = konnect_gateway_service.my_service.id
  }
}

The following examples provide some typical configurations for enabling the request-transformer-advanced plugin on a route.

Kong Admin API

Konnect API

Kubernetes

Declarative (YAML)

    --data '
    {
  "name": "request-transformer-advanced",
  "config": {
    "remove": {
      "body": [
        "formparam-toremove",
        "formparam-another-one"
      ]
    },
    "replace": {
      "body": [
        "body-param1:new-value-1",
        "body-param2:new-value-2"
      ]
    },
    "rename": {
      "body": [
        "param-old:param-new",
        "param2-old:param2-new"
      ]
    },
    "add": {
      "querystring": [
        "new-param:some_value",
        "another-param:some_value"
      ]
    }
  }
}
    '

Replace ROUTE_NAME|ID with the id or name of the route that this plugin configuration will target.

Make the following request, substituting your own access token, region, control plane ID, and route ID:

    - param2-old:param2-new
  add:
    querystring:
    - new-param:some_value
    - another-param:some_value
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the ingress as follows:

kubectl annotate ingress INGRESS_NAME konghq.com/plugins=request-transformer-advanced-example

Replace INGRESS_NAME with the name of the ingress that this plugin configuration will target. You can see your available ingresses by running kubectl get ingress.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:

      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_request_transformer_advanced" "my_request_transformer_advanced" {
  enabled = true

  config = {
    remove = {
      body = ["formparam-toremove", "formparam-another-one"]
    }
    replace = {
      body = ["body-param1:new-value-1", "body-param2:new-value-2"]
    }
    rename = {
      body = ["param-old:param-new", "param2-old:param2-new"]
    }
    add = {
      querystring = ["new-param:some_value", "another-param:some_value"]
    }
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  route = {
    id = konnect_gateway_route.my_route.id
  }
}

The following examples provide some typical configurations for enabling the request-transformer-advanced plugin on a consumer.

Kong Admin API

Konnect API

Kubernetes

Declarative (YAML)

Konnect Terraform

Make the following request:

curl -X POST http://localhost:8001/consumers/{consumerName|Id}/plugins \
    --header "accept: application/json" \

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

First, create a KongPlugin resource:

echo "
apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: request-transformer-advanced-example
plugin: request-transformer-advanced
config:
  remove:

    - param2-old:param2-new
  add:
    querystring:
    - new-param:some_value
    - another-param:some_value
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the KongConsumer object as follows:

kubectl annotate KongConsumer CONSUMER_NAME konghq.com/plugins=request-transformer-advanced-example

Replace CONSUMER_NAME with the name of the consumer that this plugin configuration will target. You can see your available consumers by running kubectl get KongConsumer.

To learn more about KongConsumer objects, see Provisioning Consumers and Credentials.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:
- name: request-transformer-advanced
  consumer: CONSUMER_NAME|ID
  config:
    remove:
      body:
      - formparam-toremove
      - formparam-another-one
    replace:
      body:
      - body-param1:new-value-1
      - body-param2:new-value-2
    rename:
      body:
      - param-old:param-new
      - param2-old:param2-new
    add:
      querystring:
      - new-param:some_value
      - another-param:some_value

Replace CONSUMER_NAME|ID with the id or name of the consumer that this plugin configuration will target.

Prerequisite: Configure your Personal Access Token

terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_request_transformer_advanced" "my_request_transformer_advanced" {
  enabled = true

  config = {
    remove = {
      body = ["formparam-toremove", "formparam-another-one"]
    }
    replace = {
      body = ["body-param1:new-value-1", "body-param2:new-value-2"]
    }
    rename = {
      body = ["param-old:param-new", "param2-old:param2-new"]
    }
    add = {
      querystring = ["new-param:some_value", "another-param:some_value"]
    }
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  consumer = {
    id = konnect_gateway_consumer.my_consumer.id
  }
}

A plugin which is not associated to any service, route, consumer, or consumer group is considered global, and will be run on every request.

In self-managed Kong Gateway Enterprise, the plugin applies to every entity in a given workspace.
In self-managed Kong Gateway (OSS), the plugin applies to your entire environment.
In Konnect, the plugin applies to every entity in a given control plane.

Read the Plugin Reference and the Plugin Precedence sections for more information.

The following examples provide some typical configurations for enabling the Request Transformer Advanced plugin globally.
