Inject cert metadata into HTTP headers and define header namev3.0+
Injects the client certificate in an HTTP header with the name X-Forwarded-Client-Cert.
Prerequisites
- This plugin must be used in conjunction with another plugin that requests a client certificate, such as the mTLS Authentication or TLS Handshake Modifier plugins.
Add this section to your kong.yaml configuration file:
_format_version: "3.0"
plugins:
- name: tls-metadata-headers
config:
inject_client_cert_details: true
client_cert_header_name: X-Forwarded-Client-Cert
Make the following request:
curl -i -X POST http://localhost:8001/plugins/ \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data '
{
"name": "tls-metadata-headers",
"config": {
"inject_client_cert_details": true,
"client_cert_header_name": "X-Forwarded-Client-Cert"
},
"tags": []
}
'
Make the following request:
curl -X POST https://{region}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/plugins/ \
--header "accept: application/json" \
--header "Content-Type: application/json" \
--header "Authorization: Bearer $KONNECT_TOKEN" \
--data '

"config": {
"inject_client_cert_details": true,
"client_cert_header_name": "X-Forwarded-Client-Cert"
},
"tags": []

Make sure to replace the following placeholders with your own values:
-
region: Geographic region where your Kong Konnect is hosted and operates. -
KONNECT_TOKEN: Your Personal Access Token (PAT) associated with your Konnect account. -
controlPlaneId: Theidof the control plane.
