user type

A user object contains information about a Slack workspace user.

If you develop for Enterprise Grid, there's a lot to consider about the most important field in a user object: the id or user_id. Learn more about global IDs and migration.

Common fields

The composition of user objects can vary greatly depending on the API being used, or the context of each Slack workspace. Data that has not been supplied may not be present at all, may be null, or may contain an empty string.

Therefore, consider the following a non-exhaustive list of potential user object fields you might encounter.

Field Type Description
always_active Boolean Indicates that a bot user is set to be constantly active in presence status.
color String Used in some clients to display a special username color.
deleted Boolean This user has been deactivated when the value of this field is true. Otherwise the value is false, or the field may not appear at all.
enterprise_user Object An object containing info related to an Enterprise Grid user. See our Enterprise grid documentation for more detail.
enterprise_user.enterprise_id String A unique ID for the Enterprise Grid organization this user belongs to.
enterprise_user.enterprise_name String A display name for the Enterprise Grid organization. String This user's ID - some Grid users have a kind of dual identity — a local, workspace-centric user ID as well as a Grid-wise user ID, called the Enterprise user ID. In most cases these IDs can be used interchangeably, but when it is provided, we strongly recommend using this Enterprise user id over the root level user id field.
enterprise_user.is_admin Boolean Indicates whether the user is an Admin of the Enterprise Grid organization.
enterprise_user.is_owner Boolean Indicates whether the user is an Owner of the Enterprise Grid organization.
enterprise_user.teams String[] An array of workspace IDs that are in the Enterprise Grid organization.
has_2fa Boolean Describes whether two-factor authentication is enabled for this user.
id String Identifier for this workspace user. It is unique to the workspace containing the user. Use this field together with team_id as a unique key when storing related data or when specifying the user in API requests. We recommend considering the format of the string to be an opaque value, and not to rely on a particular structure.
is_admin Boolean Indicates whether the user is an Admin of the current workspace.
is_app_user Boolean Indicates whether the user is an authorized user of the calling app.
is_bot Boolean Indicates whether the user is actually a bot user. Bleep bloop.
is_invited_user Boolean Indicates whether the user signed up for the workspace directly (false or the field is absent), or they joined via an invite (true).
is_owner Boolean Indicates whether the user is an Owner of the current workspace.
is_primary_owner Boolean Indicates whether the user is the Primary Owner of the current workspace.
is_restricted Boolean Indicates whether or not the user is a guest user. Use in combination with the is_ultra_restricted field to check if the user is a single-channel guest user.
is_stranger Boolean If true, this user belongs to a different workspace than the one associated with your app's token, and isn't in any shared channels visible to your app. If false (or this field is not present), the user is either from the same workspace as associated with your app's token, or they are from a different workspace, but are in a shared channel that your app has access to. Read our shared channels docs for more detail.
is_ultra_restricted Boolean Indicates whether or not the user is a single-channel guest.
locale String Contains a IETF language code that represents this user's chosen display language for Slack clients. Useful for localizing your apps.
name String Don't use this. It once indicated the preferred username for a user, but that behavior has fundamentally changed since.
profile Object An object containing the default fields of a user's workspace profile. A user's custom profile fields may be discovered using users.profile.get.
profile.display_name_normalized String The display_name field, but with any non-Latin characters filtered out.
profile.display_name String Indicates the display name that the user has chosen to identify themselves by in their workspace profile. Do not use this field as a unique identifier for a user, as it may change at any time. Instead, use id and team_id in concert.
profile.image_* String These various fields will contain https URLs that point to square ratio, web-viewable images (GIFs, JPEGs, or PNGs) that represent different sizes of a user's profile picture.
profile.real_name_normalized String The real_name field, but with any non-Latin characters filtered out.
profile.real_name String The real name that the user specified in their workspace profile.
two_factor_type Enum (String) Indicates the type of two-factor authentication in use. Only present if has_2fa is true. The value will be either app or sms.
tz String A human-readable string for the geographic timezone-related region this user has specified in their account.
tz_label String Describes the commonly used name of the tz timezone.
tz_offset Integer Indicates the number of seconds to offset UTC time by for this user's tz.
updated String A unix timestamp indicating when the user object was last updated.

Accessing email addresses
The OAuth scope is now required to access the email field in user objects returned by the users.list and web API methods. users:read is no longer a sufficient scope for this data field. Learn more.
