# Action


Information about an action.

Each rule must include exactly one of the following routing actions: `forward`, `fixed-response`, or `redirect`, and it must be the last action to be performed.

Optionally, a rule for an HTTPS listener can also include one of the following user authentication actions: `authenticate-oidc`, `authenticate-cognito`, or `jwt-validation`.
