Quoting from their [Securing Applications and Services Guide](https://www.keycloak.org/docs/latest/securing_apps/index.html#how-token-exchange-works): > Token exchange in Keycloak is a very loose implementation of the OAuth Token Exchange specification at the IETF.

It is a simple grant type invocation on a realm’s OpenID Connect token endpoint. -- This is an automated message from the Apache Git Service.
