Selectively adding users to channels in a group-based communication system

A method for adding new users to a shared channel in a group-based communication system, the method comprising:

• providing, to a first user of the group-based communication system, a first user interface component for receiving one or more requests to add one or more users to the shared channel, the one or more requests comprising a portion of at least one user identifier corresponding to the one or more users, the at least one user identifier includes an email domain;
• based on organization metadata between the one or more users and one or more other users of the group-based communication system, automatically classifying the at least one user identifier as being related to an organization corresponding to that of the first user based on organizational metadata identifying one or more domains previously associated with an organizational domain corresponding to the first user;
• in response to classifying the at least one user identifier as being related to the organization corresponding to that of the first user, providing a second user interface component for specifying whether the one or more users should be added to the shared channel;
• and
• adding the one or more users to the shared channel as members of the shared channel.

An apparatus for adding new users to a shared channel in a group-based communication system, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the apparatus to:
• provide, to a first user of the group-based communication system, a first user interface component for receiving one or more requests to add one or more users to the shared channel, the one or more requests comprising a portion of at least one user identifier corresponding to the one or more users, the at least one user identifier includes an email domain;
• based on organization metadata between the one or more users and one or more other users of the group-based communication system, automatically classify the at least one user identifier as being related to an organization corresponding to that of the first user based on organizational metadata identifying one or more domains previously associated with an organizational domain corresponding to the first user;
• in response to classifying the at least one user identifier as being related to the organization corresponding to that of the first user, provide a second user interface component for specifying whether the one or more users should be added to the shared channel;
• and
• add the one or more users to the shared channel as members of the shared channel.

A non-transitory computer-readable medium storing code for adding new users to a shared channel in a group-based communication system, the code comprising instructions executable by one or more processors to:

• provide, to a first user of the group-based communication system, a first user interface component for receiving one or more requests to add one or more users to the shared channel, the one or more requests comprising a portion of at least one user identifier corresponding to the one or more users, the at least one user identifier includes an email domain;
• based on organization metadata between the one or more users and one or more other users of the group-based communication system, automatically classify the at least one user identifier as being related to an organization corresponding to that of the first user based on organizational metadata identifying one or more domains previously associated with an organizational domain corresponding to the first user;
• in response to classifying the at least one user identifier as being related to the organization corresponding to that of the first user, provide a second user interface component for specifying whether the one or more users should be added to the shared channel;
• and
• add the one or more users to the shared channel as members of the shared channel.
