Rough Explanation for Response users type(only major)


id of user each. this num set for everyone individually as identificator in slack


id of workspace. on API response, expressed as team that is old name of workspace. be carefull

user.name/ user.real_name

user.name == user.profile.display_name: name when mention to someone (@….)

user.real_name == user.profile.real_name: actual registration name

The two are basically same, however some case that have changed the display name (initial or just the name), which cause a difference between user.name and user.real_name.


Users who have / have been in the workspace and are currently out of the workspace. True if not (not affiliated), False if affiliated

As described at the very beginning of the “function” section, this is an API for requesting a list of users who have / have previously belonged to the Slack workspace, so the current affiliation status is displayed.

user.profile.image & user.profile.image_24/32/48/72/192/512

icon pict. “.image” is original pict. after image_24/… is the data for each resolution

is_admin/is_owner (such as is_ info) 

“is_” is response status that the user has rights or not by each category

Notes and Usage

regarding this endpoint, before checking reference, I think that the userlist api is extracting currently used (active) the user + bot, but in fact you can get a list of users + bot also who have registered in the past.

if you wanna use this endpoint as following purpose, do as:

Purpose: Get the currently active users (including bot)
Do: after getting response by JSON, extracting as user.deleted==false

Purpose: Make a list of retired employees (If you have not released Slack to anyone other than an employee such as a subcontractor, and all employees are registered as users)
Do: after getting response byJSON, extracting as “user.deleted==true” and “user.is_bot==false”
