Box integrates with Slack in two ways:

• Box for Slack enables you to interact with your Box content from within Slack.
• Box File Picker enables you to import files from Box into Slack directly from the Slack application.

Box for Slack

The Box for Slack integration provides greater visibility and granular control into how Slack accesses and manages Box content and metadata. The Box for Slack integration enables you to access Box content from directly within the Slack client. This integration:

• allows Slack client app to display dynamic, scrollable high-resolution previews;
• displays file thumbnails and the file title for Box links shared in Slack;
• enables instant permissions – enables your account holders to grant extended permissions if everyone in a Slack channel or group does not have permission in Box to access content;
• enables creation of default instant permissions - enables your account holders to define the default adjustment of shared link settings for a shared Box file. With this option enabled and configured, when someone in a Slack conversation or channel does not have access to the shared Box file, Box automatically applies the default permissions defined by the account holder;
• enables slash commands (/box recents, /box favorites, /box search);
• provides granular control settings for Box admins;
• allows Box to be the content layer for Slack - you can also use Box as the Custom Files Store in Slack, where Box acts as the single content layer supporting all your conversations. See Box as the Content Layer for Slack to learn more;
• enables Slackbot integration (optional) - connects to Box MCP server allowing Slackbot to perform user-requested actions in Box like reading and updating file contents, managing collaborators or hubs, and more;
• provides users with the Share with Slack option for files browsed and previewed from Box Web. See this article to learn more; and
• allows users to receive Box event notifications in Slack.

Box File Picker

Box File Picker enables you to use Slack to import a file from Box with a Slack shortcut. This integration is owned by Slack, not Box.

To require people to store all content shared with Slack in Box, turn off native file uploads and sharing, or consider setting Box as the content layer for Slack. To do this, please contact feedback@slack.com or your designated Slack CSM.

Installing the Box for Slack integration

You must enable this integration in two places:

1. the Box admin console
2. the Slack App directory

Part 1: Enabling Box for Slack in the Box admin console

1. From your admin console, navigate to Integrations and search for “Slack”.
2. When the entry for Box for Slack displays, change the status to Available or Added by default.

3. To change additional configuration settings, hover your pointer over the Box for Slack app and click Configure. For the best user experience, follow Steps 4-6.

4. To see when a file is shared in a Slack channel, in File Preview in Box, toggle the Enable Box Activity Stream slider to On.
5. To display a full content card of the first page of a Box file when shared, toggle the Enable file thumbnails slider to On.
   • If you leave this toggle off, Slack displays the generic file type icon in place of a thumbnail image of the first page of the file.

6. To enable your Box account holders to join the Box for Slack integration without manually authorizing the app to access their Box account, under Admin Delegated Authorization select an enablement option.  The Box account of an authorized Slack user is recognized based on either:
   • the user's existing Box webapp session, or
   • the user's allowlisted Slack Org/Workspace profile e-mail address.
7. To enable Slack to index and store text content from shared Box files, toggle the Enable context indexing for Slack search slider to toggle On. This improves search accuracy when you search within Slack.
   • If you leave this toggle off, Slack only indexes and stores the file name.
8. To enable the Share with Slack option for files you browsed or previewed in Box Web, toggle the Share with Slack slider to On.
9. For more robust security settings, enable Steps 10-11 (if applicable).

10. To add an additional layer of security before displaying a content card (filename and thumbnail) of a Box file when shared, toggle the Enforce additional permissions check before file display slider to On. The file content card unfurls only if:
    • everyone in the channel or group are authenticated into Box, and
    • everyone in the channel can view/access the shared file.
11. Optionally, restrict the integration to work only with specific Slack workspaces (that is, place certain domains on an allow list).
    • To restrict the integration to specific Slack organizations, in the Restrict to specific Slack Enterprise Grid Org ID allowlist box, type your organization’s Slack Enterprise Grid Org IDs. This option is available only to Slack Enterprise Grid customers. Separate multiple IDs with commas.
    • To restrict the integration to specific Slack workspace domains (such as acme.slack.com, acme-marketing.slack.com, and so on), in the Restrict to specific Slack workspaces allowlist box, type in the specific Slack domains. Separate multiple domains with commas.
    • To allow any Box for Slack integration to connect to your Box enterprise, leave clear the Restrict to specific Slack Enterprise Grid Org ID allowlist and Restrict to specific Slack workspaces allowlist options above.
      • If you complete this option you connect one Box EID to one or more Slack enterprise organizations.
      • Only people from these Slack enterprises can access your Box enterprise.
      • Only people from these Slack domains can access your Box enterprise.
12. When you’re done, click Save.

Part 2: Enabling Box for Slack in the Slack App directory

1. Follow Slack’s standard instructions for enabling a third-party app in Slack for your workspace.
2. Navigate to the Slack app store and search for “Box.” Then enable the integration.
3. When you’re done, the option to add Slack becomes available to everyone for whom you’ve enabled the integration. When one person installs the integration in their workspace, the integration becomes available to everyone else in that workspace.
4. Review Slack’s instructions for individual account holders to add Slack to their respective workspaces.

Part 3: Enabling Box AI for Slack

1. From the admin console, go to Integrations, then search for "Box for Slack".
2. Click Configure on Box for Slack.
3. Toggle on for “Enable Box AI for Slack”
   • To show “Ask Box AI” under a shared file, toggle on the option.
4. Decide if your users can remove Box AI responses:
   • Toggle on “Allow anyone to remove Box AI responses”.
     • Enabling this setting will allow anyone within the organization on Slack Enterprise to remove the response.
   • If not enabled, only enterprise admins can remove Box AI responses.
5. If applicable, add Organization IDs under Restrict Box AI features to specific Slack Enterprise Grid Org ID allowlist.
6. If applicable, add workspace IDs under Restrict Box AI features to specific Slack workspace allowlist.
7. Click Save.
