# Update an mTLS configuration

> Renames a configuration, replaces its certificate, or both. Only the fields present in the request are changed; anything omitted is left as it is, and a request with neither field is rejected with a `400`.

Replacing `signedCert` switches every webhook using this configuration over to the new certificate in one write, and the private key it was issued for is re-derived from the certificate. A replacement that was not issued for a private key this workspace holds is rejected with a `400`.

Sending `name: null` removes the label.

**Endpoint Permissions:** Owner, Admin, Non-Signing Admin.
