# Regenerate signing secret

`POST /environments/{environment_key}/regenerate_signing_secret`

Regenerate environment signing secret. Once this is regenerated, the old signing secret will no longer be valid and you must immediately update your application with the new signing secret. This call should be authenticated with the key of the environment that you are trying to update and an Organization Access Secret.
