post
https://console.neon.tech/api/v2/projects//branches//credentials//reveal
Returns the live api_token and s3_secret_access_key of an existing
credential, so a credential whose issuance response was lost can be
recovered without minting a new one.
This is a POST with an explicit /reveal verb so the secrets never ride
a GET, where they would land in access logs, browser history and proxy
caches. Revoked and expired credentials return 404, as does a
token_id that does not belong to this project.
A credential issued before secret retrieval was supported has no
recoverable secret and returns 409 — rotate it to obtain one.
Note: This endpoint is currently in Beta.
