Account requirements
PreauthSignals accepts a Methodaccount_id for a liability-backed credit card Account.
The Account must not be disabled and its consent must not be withdrawn. Closed Accounts
are supported and return a completed assessment with success_likelihood: 0.
The assessment is synchronous. POST /preauth returns the completed or failed
PreauthSignals object after processing finishes.
PreauthSignals is available only with API version

Insufficient data
When Method cannot compute a prediction from sufficiently recent liability data, the assessment still returnsstatus: "completed". In that case, success_likelihood and
optimal_retry_date are null, and error.sub_type is PREAUTH_INSUFFICIENT_DATA.
If the Account’s underlying liability cannot be found, the assessment returns
status: "failed" with error.sub_type: "PREAUTH_FAILED_LIABILITY_NOT_FOUND".
