Profile

The profile hash contains as much information as the user has supplied in the default profile fields: first_name, last_name, real_name, email, skype, and the image_* fields. Only the image_* fields are guaranteed to be included. Data that has not been supplied may not be present at all, may be null or may contain the empty string ("").

A user's custom profile fields may be discovered using users.profile.get.

Email addresses

Apps created after January 4th, 2017 must request both the users:read and users:read.email OAuth permission scopes when using the OAuth app installation flow to enable access to the email field of user objects returned by this method.

Pagination

This method uses cursor-based pagination to make it easier to incrementally collect information. To begin pagination, specify a limit value under 1000. We recommend no more than 200 results at a time.

Responses will include a top-level response_metadata attribute containing a next_cursor value. By using this value as a cursor parameter in a subsequent request, along with limit, you may navigate through the collection page by virtual page.

See pagination for more information.

Legacy behavior

At this time, providing no limit value will result in Slack attempting to deliver you the entire result set. If the collection is too large you may experience HTTP 500 errors. Resolve this scenario by using pagination.

One day pagination will become required to use this method.

Errors

This table lists the expected errors that this method could return. However, other errors can be returned in the case where the service is down or other unexpected factors affect processing. Callers should always check the value of the ok params in the response.

Error Description
invalid_cursor

Value passed for cursor was not valid or is no longer valid.

not_authed

No authentication token provided.

invalid_auth

Invalid authentication token.

account_inactive

Authentication token is for a deleted user or workspace.

invalid_arg_name

The method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than _. If you get this error, it is typically an indication that you have made a very malformed API call.

invalid_array_arg

The method was passed a PHP-style array argument (e.g. with a name like foo[7]). These are never valid with the Slack API.

invalid_charset

The method was called via a POST request, but the charset specified in the Content-Type header was invalid. Valid charset names are: utf-8 iso-8859-1.

invalid_form_data

The method was called via a POST request with Content-Type application/x-www-form-urlencoded or multipart/form-data, but the form data was either missing or syntactically invalid.

invalid_post_type

The method was called via a POST request, but the specified Content-Type was invalid. Valid types are: application/x-www-form-urlencoded multipart/form-data text/plain.

missing_post_type

The method was called via a POST request and included a data payload, but the request did not include a Content-Type header.

team_added_to_org

The workspace associated with your request is currently undergoing migration to an Enterprise Organization. Web API and other platform operations will be intermittently unavailable until the transition is complete.

request_timeout

The method was called via a POST request, but the POST data was either missing or truncated.

Warnings

This table lists the expected warnings that this method will return. However, other warnings can be returned in the case where the service is experiencing unexpected trouble.

Warning Description
missing_charset

The method was called via a POST request, and recommended practice for the specified Content-Type is to include a charset parameter. However, no charset was present. Specifically, non-form-data content types (e.g. text/plain) are the ones for which charset is recommended.

superfluous_charset

The method was called via a POST request, and the specified Content-Type is not defined to understand the charset parameter. However, charset was in fact present. Specifically, form-data content types (e.g. multipart/form-data) are the ones for which charset is superfluous.
