## Update a quote

`PATCH /v1/quotes/:id`

Updates fields of an existing CRM quote. Pass only the fields being changed. Full list in the [field reference](/docs/entities/quotes/fields), including user fields (`ufCrm_*`).

## Frequently updated fields

| Parameter | Type | Description |
|----------|-----|---------|
| `stageId` | string | Status: `DRAFT`, `SENT`, `APPROVED`. List: `GET /v1/statuses?filter[entityId]=QUOTE_STATUS` |
| `opportunity` | number | Quote amount. Pass it together with `isManualOpportunity: true`, otherwise Bitrix24 will recalculate the amount from line items (the flag is stored as `Y`/`N`; the boolean is converted automatically) |
| `assignedById` | number | Assignee. List: `GET /v1/users` |
| `title` | string | Name |
| `closedate` | datetime | Close date |

> **Field names.** In responses, fields are returned in camelCase: `amount`, `currency`, `beginDate`, `closeDate`. On write, both variants are accepted — these camelCase names and the B24-native `opportunity` / `currencyId` / `begindate` / `closedate`: the API layer maps them to the name Bitrix24 expects.
