Handle OIDC Client Authentication Callback & Token Exchange

Webhook

Webhook Trigger

This n8n workflow operates as an OpenID Connect (OIDC) client, specifically designed to manage the critical post-authentication steps of an OIDC flow. It is initiated by a Webhook node, which serves as the redirect URI for an OIDC provider. Upon successful user authentication, the provider sends an authorization code to this webhook. The workflow then leverages a Code node to process the incoming request, extract the authorization code, and prepare the necessary data for token exchange. Subsequent Http Request nodes are utilized to securely communicate with the OIDC provider's token endpoint. Here, the authorization code is exchanged for an ID token, access token, and potentially a refresh token. This automated process is fundamental for applications requiring robust user authentication via OIDC-compliant identity providers, abstracting away the complexities of manual token retrieval and ensuring secure, efficient integration.
