# Custom field values per project

These operations support creating, reading, updating, and deleting custom field values with respect to projects.

> **Note:** In addition to getting custom field values directly, you can also include custom field values as a nested collection when getting projects by specifying `custom_field_values` in the `fields` parameter.
> 
> For example, 
> 
> `GET /api/v1/projects/<project_id>?fields=custom_field_values`
