Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| expense_id | string | yes | |
| title | string | no | |
| amount | number | no | |
| currency | string | no | ISO 4217 code, e.g. USD, EUR, THB |
| spent_on | string | no | ISO date, e.g. 2026-08-01 |
| category | string | no | One of the app's expense categories. Food is 'restaurant'. |
| stay_id | string | no | |
| related_event_id | string | no | |
| amount_usd | number | no | The same amount in USD, frozen at entry. Set it ONLY when the source states a USD (or already-converted home-currency) figure. Omit otherwise — the app converts at the live rate, which is honest, whereas a guessed historical rate is frozen forever. |
