**custom.FIELD_ID** (optional)
- See description for `custom.FIELD_ID` in `POST /opportunity/` above.
- Additionally, you can unset a single field by using `{ "custom.FIELD_ID": null }`, e.g.:
```
{ "custom.cf_v6S011I6MqcbVvB2FA5Nk8dr5MkL8sWuCiG8cUleO9c": null }
```
If you're trying to update a custom field and that custom field accepts multiple values, you can also specify `.add` or `.remove` as part of the field key to add/remove a single value to/from a list of values, e.g.:
```
{ "custom.cf_v6S011I6MqcbVvB2FA5Nk8dr5MkL8sWuCiG8cUleO9c.add": "Wednesday" }
```
Request
This endpoint expects an object.
attachmentslist of objectsOptional
confidenceintegerOptional
contact_idstring or nullOptional
date_wondatetime or nullOptional
If not set on the resource or in the request, date_won will be set automatically to today’s date when setting status_id to a status with type won. The x-tz-offset header, used to pass your timezone’s UTC offset, will be taken into account.
notestringOptional
Plaintext/markdown version of the note. If note_html is also provided in the same request, this value is ignored and note is derived from the HTML instead.
note_htmlstring or nullOptional
Rich-text HTML version of the note. When set, note is automatically populated with the plaintext version (tags become markdown), overriding any note value passed in the same request. Pass null to clear note_html; note is cleared as well.
status_idstringOptional
Setting the status_id to a status with a type of won will automatically set the date_won field if it is not already set or provided in the request. Reverting it from a won status to an active or lost will not automatically change date_won.
user_idstring or nullOptional
