Box helps business of all sizes in every industry securely collaborate and manage their content in the cloud. This integration will import Box files into Slack. • To import files from your Box account, use the Add File button in Slack (it’s beside the message input), or just include a shared link to the file in a message. • Imported files will be automatically updated when the corresponding Box file is updated. • Imported files are searchable and shareable but will continue to be stored in your Box account.
