# List sandbox behaviours

> Sandbox only — responds 404 on production. An index of every deterministic sandbox behaviour: the POST simulation endpoints below, plus the triggers built into the normal API. Collections and payouts pick their outcome from the last two decimal digits of `amount` (e.g. a payout of `100.01` is rejected, `100.03` times out then reconciles; any other cents complete). Account validation picks its outcome from the `accountNumber` suffix (`000000` not found, `000001` closed, `000002` timeout; anything else is valid).
