Abstract: Generating shared workspaces for enabling communications between users of different organizations and facilitating discovery of users associated with different organizations is described. A first user can generate a shared workspace and associate one or more other organizations therewith. The first user can designate first criteria associated with joining the shared workspace. The communication platform can receive a request from a second user to join the shared workspace. Based on a determination that the second user satisfies the first criteria, the communication platform can enable the second user access to the shared workspace. In some examples, an administrator associated with an organization of the second user can establish second criteria for users of the organization to join the shared workspace. In such examples, the communication platform can enable the second user access to the shared workspace based on a determination that the second user also satisfies the second criteria.

Abstract: Managing organization disconnections from a shared resource of a communication platform is described. In a sharing approval repository of a communication platform, a shared resource can be associated with a host organization identifier and a non-host organization identifier. In an example, in response to receiving, from a user computing device associated with the host organization identifier or the non-host organization identifier, a resource disconnection request comprising a disconnecting organization identifier and a resource identifier associated with the shared resource, the sharing approval repository can be updated to add a disconnection indication for the resource identifier in association with the disconnecting organization identifier.

Abstract: Multi-workspace shared communication channels described. A communication channel of a group-based communication platform can be associated with multiple group identifiers to associate the communication channel with at least two workspaces, wherein a first group identifier corresponds to a first workspace within which a first group communicates and a second group identifier corresponds to a second workspace within which a second group. The communication channel can be associated with multiple organization identifiers to associate the communication channel with at least two organizations, wherein a first organization identifier corresponds to a first organization and a second organization identifier corresponds to a second organization.

Abstract: Management of hosted channel membership of a communication platform is described. A request can be received from a first client of a first user, associated with a first organization, of the group-based communication platform, wherein the request is to associate a second user, associated with a second organization, with a communication channel of the first organization. An invitation to join the communication channel can be sent to a second client of the second user. In response to receiving an indication of an acceptance of the invitation, the second user can be associated with the communication channel. A request can be received from the second client to associate other user(s) associated with the second organization with the communication channel and the other user(s) can be associated with the communication channel based at least in part on permission(s) associated with the communication channel.

Abstract: Generating a shared workspace communication is described. A communication platform can receive, from a first account of a first workspace associated with a first organization, a request to create a shared workspace between the first organization and a second organization associated with a second workspace, wherein the first workspace comprises a first set of functions and the second workspace comprises a second set of functions. Based on the request, the communication platform can generate the shared workspace which may be accessible to one or more first users associated with the first workspace and one or more second users associated with the second workspace. The communication platform can assign a set of permissions to interact with the shared workspace to the one or more first users and the one or more second users to interact with the shared workspace. In some examples, the communication platform may generate a channel in the shared workspace.

Abstract: Techniques are described for expediting communications between a first person of an organization associated with a communication platform and a second person not associated with the organization. The first person requests for the communication platform to generate an invitation to communicate with the second person. The first person provides the invitation to the second person directly or via the communication platform. Responsive to receiving an indication that the second person accepts the invitation, the communication platform identifies whether the second person is associated with the communication platform. If the second user is associated with the communication platform, the communication platform modifies an existing user interface associated therewith to enable communications between the first person and the second person.

Abstract: Techniques are described for providing an interface for managing invitations to communicate via a communication platform. In an example, a first user can access a first interface to invite a second user to communicate via the communication platform. In response to input from the first user via the first interface, the communication platform can generate an invitation for the second user to communicate with the first user and can provide the invitation to the second user, such as by causing the invitation to be presented via a second interface. The second user can submit a response to the invitation via the second interface. The communication platform can update the first interface and the second interface based on response, such as, in examples in which the second user accepts the invitation, to reflect a newly established connection between the first user and the second user.

Abstract: Media, system, and method for providing encryption key management to a channel within a group-based communication system. The contents of the channel is encrypted according to the encryption key management policy of the organization to which the author of the content belongs and is stored in a data store. Responsive to a revocation request from a first organization, the encryption keys associated with any content in the channel submitted by the authors of said first organization may be revoked from a second organization, such that users of the second organization no longer have access to the content.

Abstract: Techniques for enabling access to external data of a user for facilitating communications via a communication platform are described herein. A user of the communication platform maintains external data with a third-party service provider. The communication platform receives, in association with a user account of the user, an indication of intent to grant the communication platform access to the external data and an authorization code (the “code”). The communication platform later receives, from the first user account, a request to access the external data. For example, the request can include an input corresponding to an intended recipient of a message. In response to the input, the communication platform sends a request, with the code, to the third-party service provider to obtain contact data associated with the intended recipient and causes the contact data to be presented in association with the message, such as in a “To” field of the message.

Abstract: The present disclosure is related to virtual spaces, such as channels, of a communication platform. In some cases, a channel may be designated as a private channel, which may permit access to the private channel by only users joined to the channel and may restrict/prevent access by all other users. The present disclosure is related to solutions for changing the private channel to a public channel, which may allow additional user accounts that were not associated with the private channel to discover and/or access the converted channel.
