-When a guard rejects content, {{< reuse "agw-docs/snippets/agentgateway.md" >}} returns a `403` response by default. Set `response.message` to return a custom response body, `response.statusCode` to change the status code, or both. You can set the `response` field on any request or response guard except a `webhook` guard, which ignores it. A webhook sets the status code and body of its own rejections.

 The `response` settings apply only when the guard rejects content. They do not apply to a guard in `Audit` mode or to a regex guard that masks content.
