The Box for Slack integration can be used to set Box as the Custom Files Store (content layer) for Slack. In this mode, all uploads that users make in Slack are automatically landing in Box. The integration creates a default structure of Box folders for those uploads, reflecting and mapping the Slack hierarchy of workspaces and channels.
Box admins are now able to map a custom Box upload folder for selected Slack channel.
This customization is available via new Box API Integration Mapping endpoints. It is well suited for situations in which a particular Slack channel already has a corresponding folder in Box and allows to map it for uploads instead of using the automatically created folder within the default structure.
