Installing and Using the Box for Slack Integration

The Box for Slack integration enables you to share content from your Box repository directly from the Slack message interface and gives you greater visibility and granular control into how Slack accesses and manages Box content and metadata. You get the ease of sharing and communication provided by the popular Slack platform, with the content management and security features of Box. 

With the Box for Slack integration, you can:

• Preview content with rich file thumbnails along with the file title for Box links shared in Slack.
• Grant access with instant permissions to channel or chat participants – that is, prompt people to grant expanded permissions if not everyone in a Slack channel or group has permission in Box to view/access content.
• Default instant permissions - define the default adjustment of shared link settings for a shared file.  If you enable and configure this option, when someone in a Slack conversation or channel doesn't have access to the shared file, Box automatically applies the default permissions you defined.
• Search and share Box content via slash commands (/box recents, /box favorites, /box search).
• Control access and display settings granularly for Box admins.
• Use Box as the content layer for Slack, where Box acts as the single content layer supporting all your conversations. To learn more, see this article. 

Note:  In addition to this Slack integration, we also have the “Share with Slack” integration that enables you to share Box content to Slack directly from the Box file preview screen. More on the Share with Slack integration. Furthermore, there is the "Box File Picker" that allows you to share Box content in Slack using the to the right of the Slack message box.

Enabling the integration

After your organization’s Box admin enables the Box for Slack integration, you must install it for your account. To do this:

1. Log in to your Slack account with your Slack credentials.
2. Go to the Box entry in the Slack app store and click Sign in to Install.
3. Click Continue.
4. Log on to Box and follow the prompts. When prompted to grant Slack access to your Box files, click OK.

If you attempt to send a shared link over Slack before you have installed the integration, the system prompts you to install it.

You can begin using the integration immediately after you enable it to:

• Send links to Box content to individuals and to Slack channels.
• Browse through lists of your favorite and most recently accessed files.
• Use Slack to search through Box content.

If you use Slack to share a Box link with someone who has not yet enabled the integration, Slack prompts them to do so, and they go through the same enablement procedure.

After they install the integration, another message introduces them to the Box for Slack features.

Sharing Box files in Slack conversations and channels

When you share a Box file in Slack, everyone in the Slack channel or conversation can see the file name, file type, and a rich preview of the file in a thumbnail image (if enabled by admin). 

When you share a link to a Box file in a channel or conversation in which not every member can access the file, the Box for Slack integration allows you to:

• add a shared link to the file, and/or modify the existing permission level of the shared link
• invite collaborators to the file at your chosen collaboration level
  • The option to set the collaboration level does not display if the number of collaborators is or could exceed 500. In other words, if the number of people already collaborating on the file, plus the number of channel members, exceeds 500, you do not get this option. Instead, everyone you invite to collaborate can only view the file.

To set the permission level, click Select an option, and in the menu that displays click the option or options you want.

You can also define default instant permissions, so Box automatically applies your preferred option.

To set up the default, visit the Box for Slack app’s App Home.

Searching Box content and accessing recents and favorites

You can type special commands directly into the Slack message box to more quickly and easily  find and share files from Box, without leaving the Slack message interface. These are called “slash commands,” because each simple command is preceded by a forward slash.

Type any of the following at the very beginning of your Slack message:

In each case Slack displays five files at a time, with a link you can use to view more files, also in sets of five.
