What is it?

The Slack Integrations widget provides a portal into your slack channels which you can view and contribute to through your digital workplace.

Features and functionality

The Slack integration widgets provide many of the features available in the Slack web interface:

View

You can see what is posted in your Slack channels through the integration. The feed shows posts and updates automatically when new entries are made from either the widget or other Slack interfaces. Scrolling through previous messages will automatically load additional messages if they exist.

Post messages

You can add new messages with the standard features Slack provides including #hashtagging   other channels, @mentioning   users, and adding emojis ;).

Upload files

You can upload files from your computer into slack. These follow the same restrictions as normal file restrictions for Slack. When uploading a file you can include a title and comment that will be published at the same time as the file upload.

Change Channel

You can select which of your existing Slack channels to display in the feed. Use the search option to quickly locate channels in addition to scrolling through the channel list.

Threaded Replies

You can create a reply thread by clicking the speech bubble icon located on a message. Messages with existing threads will contain a View Thread link that can be clicked to view the existing threaded replies.

Limitations

Slack limits the number of API calls that can be made per second from a single source. Including multiple slack widgets on a single page, or having multiple tabs open containing slack widgets may exceed this limit and cause the widgets to stop working.
