OpenID Connect: Authorization code flow - Plugin

Authorization code flow

This example configures the OpenID Connect plugin with an authorization code flow.

For a full example that shows you how to set up the authorization code flow with Keycloak, see Configure OpenID Connect with the auth code flow.

Note: Setting config.client_auth to client_secret_post lets you easily test the connection to your IdP, but we recommend using a more secure auth method in production. You can use any of the supported client auth methods.

Prerequisites

A configured identity provider (IdP)

Environment variables

ISSUER: The issuer authentication URL for your IdP. For example, if you’re using Keycloak as your IdP, the issuer URL looks like this: http://localhost:8080/realms/example-realm
CLIENT_ID: The client ID that the plugin uses when it calls authenticated endpoints of the IdP.
CLIENT_SECRET: The client secret needed to connect to your IdP.

Set up the plugin

Add this section to your declarative configuration file:

_format_version: "3.0"
plugins:
  - name: openid-connect
    config:
      issuer: ${{ env "DECK_ISSUER" }}
      client_id:

      auth_methods:
      - authorization_code
      - session
      response_mode: form_post
      preserve_query_args: true
      login_action: redirect
      login_tokens:

Make the following request:

    --header "accept: application/json" \
    --header "Content-Type: application/json" \

        "login_action": "redirect",
        "login_tokens": null
      }
    }

Make sure to replace the following placeholders with your own values:

region: Geographic region where your Kong Konnect is hosted and operates.
controlPlaneId: The id of the control plane.
KONNECT_TOKEN: Your Personal Access Token (PAT) associated with your Konnect account.
