# Assignees An assignee is anything in Silktide that can be given something: permissions, a report to receive, a check to fix. Silktide also records the assignee behind each change it logs. ## Assignee ids An assignee id says both what kind of assignee it is and which one, as a prefix and an id: | Prefix | Kind | Example | | --- | --- | --- | | `u:` | A user: a person who signs in to the account. | `u:eu-12` | | `g:` | A [role](https://developers.silktide.com/v1/platform/roles.md), such as Everyone. Roles were once called groups, hence `g`. | `g:1` | Operations that take people, such as `assigneeIds`, take these ids. [List assignees](https://developers.silktide.com/v1/platform/assignees/list-assignees.md) returns every one in the account. Silktide has other kinds of assignee, such as an API key or Silktide itself, and you may see their ids in records of who did what. List assignees returns only users and roles. In Silktide itself: [Users screen](https://docs.silktide.com/settings/screens/users), in Help. ## Operations - [List the account's roles and users as assignees](https://developers.silktide.com/v1/platform/assignees/list-assignees.md): `GET /v1/assignees`
