The first_name and last_name fields can be up to 35 characters each. The name slackbot cannot be used for either of these fields.
The email field must be a valid email address. It cannot have spaces, and it must have an @ and a domain. It cannot be in use by another member of the same team. Changing a user's email address will send an email to both the old and new addresses, and also post a slackbot to the user informing them of the change. This field can only be changed for users on paid teams.
After March 20, 2017 the skype field will always be an empty string and cannot be set otherwise. For more detail, please read this changelog entry.
The fields key is an array of key:value pairs holding the values for the user's custom profile fields. The key is the ID of the definition for that field, which is per-team. This ID can also be used in the name field of this method. The value of a field is what should be displayed, unless the alt key is also present, in which case that is displayed instead. The value can be up to 256 characters for fields of type text and link. For fields of type options_list, the value must be one of the possible_values in the field definition. For fields of type date, the value must be a valid date. The alt field can be up to 256 characters for all field types. The profile argument must be used in order to set the alt field.
This method will generate a user_change event on success, containing the complete user.
