not_revealable

Key values are shown only once, at creation (or rotation), and stored hashed.

HTTP 400.

Likely cause: An attempt to reveal an existing full, read-only or sandbox key: only a digest is stored.

What to do: Create a new key if you lost it, or rotate a read-only key to get a new value.

Retry: No. The same request gets the same answer; change something first.
