Deno Slack SDK

Workflow apps require a paid plan

Join the Developer Program and provision a sandbox with access to all Slack features for free.

You can create Slack-hosted workflows written in TypeScript using the Deno Slack SDK.

Workflows are a combination of functions, executed in order.

There are a three types of functions:

  • Slack functions enable Slack-native actions, like creating a channel or sending a message.
  • Connector functions enable actions native to services outside of Slack. Google Sheets, Dropbox and Microsoft Excel are a few of the services with available connector functions.
  • Custom functions enable developer-specific actions. Pass in any desired inputs, perform any actions you can code up, and pass on outputs to other parts of your workflows.

Workflows are invoked via triggers. You can invoke workflows:

  • via a link within Slack,
  • on a schedule,
  • when specified events occurs,
  • or via webhooks.

Workflows make use of specifically-designed features of the Slack platform such as datastores, a Slack-hosted way to store data.

While in development, you can keep your project mostly to yourself, or share it with a close collaborator. If your Slack admin requires approval of app installations, they’ll need to approve what you’re creating first.

warning

The app management UI on api.slack.com/apps doesn’t support configuring workflow apps. Also, workflow apps are currently not eligible for listing in the Slack Marketplace.
