delete
https://app.bitgo-test.com/api/policy/v1/enterprises//webhooks/keys/
Revokes a webhook signing key for an enterprise. This is a soft delete — the key row is preserved for audit purposes but marked as REVOKED.
Revoked keys cannot be used for webhook signature verification. Revocation is irreversible — a new key must be registered to restore access.
Authorization: Caller must be an admin of the specified enterprise.
