# createChatAppSecret

> Generate a signing secret for a chat app used to authenticate incoming webhook requests.
If a secret already exists for the given chat app it is deleted and replaced — the new secret
is the only time the raw value is returned. Store it securely immediately after creation.
Requires the `chatAppSecret:create` permission and the live-chat billing entitlement.
