Introducing new Slack platform features and pricing

Following the release of a new set of modular Slack platform tools for developers in April 2023, we began rolling out a new version of Workflow Builder in June 2023. Read on to learn about what’s changed.

New to Workflow Builder? Check out What is a Slack workflow? and our Build a workflow tutorial.

What's new

  • Start your workflows with a link that can be used anywhere in Slack: public or private channels, direct messages (DMs), canvases, and more.
  • Choose from several new Slack steps, or add new connector steps from third-party apps. If developers in your organization have built custom workflow steps, you'll now see them in the workflow step library.
  • Workflows built with the new version of Workflow Builder that meet certain criteria will be chargeable.
  • Starting in August 2023, we’ll begin migrating legacy workflows to the new version of Workflow Builder. Any workflows created with the legacy version that are migrated will be treated as standard workflows (even if they meet the criteria to be considered premium).

Standard and premium workflow usage

Paid Slack plans include standard workflow runs and an allotment of premium workflow runs. Whether a workflow is standard or premium depends on the types of steps it includes, and your allotment is determined by the plan you’re on.

Standard and premium workflows

  • Standard workflow
    A workflow with Slack steps or one connector step.
  • Premium workflow
    A workflow with at least one custom step or two or more connector steps. For more details on premium workflows, see our FAQs below.

Workflow usage

Workflow usage is determined by how many times a workflow is run. These are the allotments per plan:

  • Pro plan
    1,000 runs/month
  • Business+ plan
    2,000 runs/month
  • Enterprise Grid plan
    5,000 runs/month*

*Per Enterprise Grid organization, not per workspace

Customers must strictly review premium workflow runs by their users and enforce the limit set forth herein. For Slack plans purchased via the Slack website and paid for by credit card or self-serve invoicing, allotments will reset once per month and no rollover will be permitted. For all other plans, allotments will reset at the end of your billing period and no rollover will be permitted. Additionally, Customers may not use more than 50,000 premium workflow runs per hour or more than 500,000 premium workflow runs per month. Slack may review Customers’ premium workflow runs at any time through the Service. Slack reserves the right to enforce these limits in its sole discretion, which may result in Slack serving an “allotment exceeded” page or other notice to you or your users. Slack may also technologically enforce the limits set forth herein. Such limits may prevent customers from using premium workflows until additional premium workflow runs are purchased.

Note: If you exceed your allotment of premium workflow runs, pricing is based on how many times you run a premium workflow.

Promotional period

From April 24, 2023-October 31, 2023, customers will not be charged for any premium workflow runs. Starting November 1, 2023, you’ll be charged for any premium workflow runs that exceed your plan’s allotment. If you don’t exceed your allotment, you won’t be charged.


What makes a workflow standard or premium?

Currently, workflows are considered standard if they use Slack steps and premium if they include at least one custom step, or two or more connector steps.

Where can I view and monitor workflow usage?

You can view a list of workflows created with the new version of Workflow Builder from the workflow dashboard. You’ll also see a banner at the top of the dashboard page showing how much of your premium workflow allotment has been used.

How do I manage access to the new version of Workflow Builder?

We’re rolling the new version of Workflow Builder out gradually. If you’re on our Pro or Business+ plans, any existing Workflow Builder permissions will apply to the new version of Workflow Builder. Workspace Owners and Admins can adjust these permissions anytime from the workspace settings page.

If you’re an Enterprise Grid customer, we’ll have more information to share soon about when you can expect to see the new version (and the admin controls you’ll have access to).

How do I manage apps built by developers in my organization that contain custom workflow steps?

When a developer deploys their app to your workspace or org, we’ll check to see if app approval is required. If it is, the app can be reviewed and approved or restricted through your existing app approval process. When reviewing app requests, app managers will see any domains the app communicates with in addition to its scopes.

How do I manage access to connectors?

If your workspace or Enterprise Grid org requires app approval, members will see the option to request access to connectors from the step library in Workflow Builder for Workspace Owners/Admins and Org Owners/Admins to approve or deny. To learn more, visit Manage access to third-party steps in Workflow Builder.

How do I manage access to custom workflow steps?

If you’ve approved an app that contains custom workflow steps, you can restrict access to those steps. Visit Manage who can add custom steps to workflows to learn how.
