Usage info

Retrieve a single user by looking them up by their registered email address. Requires users:read.email.

Custom bot users cannot use this method.

Returns a user object.

If the user has been deactivated, users_not_found will be returned instead of a user object. Instead, you can call users.list and filter the results to find the deactivated user.

Profile

The profile hash contains as much information as the user has supplied in the default profile fields: first_name, last_name, real_name, display_name, 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

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

Apps created after January 4th, 2017 must explicitly request the users:read.email OAuth permission scope when using the OAuth app installation flow to enable access to 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
`enterprise_is_restricted`	The method cannot be called from an Enterprise.
`users_not_found`	Value passed for `user` was invalid.
`access_denied`	Access to a resource specified in the request is denied.
`account_inactive`	Authentication token is for a deleted user or workspace when using a `bot` token.
`deprecated_endpoint`	The endpoint has been deprecated.
`ekm_access_denied`	Administrators have suspended the ability to post a message.
`invalid_auth`	Some aspect of authentication cannot be validated. Either the provided token is invalid or the request originates from an IP address disallowed from making the request.
`method_deprecated`	The method has been deprecated.
`missing_scope`	The token used is not granted the specific scope permissions required to complete this request.
`not_allowed_token_type`	The token type used in this request is not allowed.
`not_authed`	No authentication token provided.
`no_permission`	The workspace token used in this request does not have the permissions necessary to complete the request. Make sure your app is a member of the conversation it's attempting to post a message to.
`org_login_required`	The workspace is undergoing an enterprise migration and will not be available until migration is complete.
`token_expired`	Authentication token has expired
`token_revoked`	Authentication token is for a deleted user or workspace or the app has been removed when using a `user` token.
`two_factor_setup_required`	Two factor setup is required.
`accesslimited`	Access to this method is limited on the current network
`fatal_error`	The server could not complete your operation(s) without encountering a catastrophic error. It's possible some aspect of the operation succeeded before the error was raised.
`internal_error`	The server could not complete your operation(s) without encountering an error, likely due to a transient issue on our end. It's possible some aspect of the operation succeeded before the error was raised.
`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_arguments`	The method was either called with invalid arguments or some detail about the arguments passed is invalid, which is more likely when using complex arguments like blocks or attachments.
`invalid_array_arg`	The method was passed an array as an argument. Please only input valid strings.
`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/json` `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.
`ratelimited`	The request has been ratelimited. Refer to the `Retry-After` header for when to retry the request.
`request_timeout`	The method was called via a `POST` request, but the `POST` data was either missing or truncated.
`service_unavailable`	The service is temporarily unavailable
`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.

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.
