# CustomFieldValueUpdate ## Properties Name | Type | Description | Notes ------------ | ------------- | ------------- | ------------- **issue_ids** | **Vec** | The list of issue IDs. | **value** | Option<[**serde_json::Value**](.md)> | The value for the custom field. The value must be compatible with the [custom field type](https://developer.atlassian.com/platform/forge/manifest-reference/modules/jira-custom-field/#data-types) as follows: * `string` the value must be a string. * `number` the value must be a number. * `datetime` the value must be a string that represents a date in the ISO format or the simplified extended ISO format. For example, `\"2023-01-18T12:00:00-03:00\"` or `\"2023-01-18T12:00:00.000Z\"`. However, the milliseconds part is ignored. * `user` the value must be an object that contains the `accountId` field. * `group` the value must be an object that contains the group `name` or `groupId` field. Because group names can change, we recommend using `groupId`. A list of appropriate values must be provided if the field is of the `list` [collection type](https://developer.atlassian.com/platform/forge/manifest-reference/modules/jira-custom-field/#collection-types). | [[Back to Model list]](../README.md#documentation-for-models) [[Back to API list]](../README.md#documentation-for-api-endpoints) [[Back to README]](../README.md)
