Pricing guide for Slack Workflow Builder

With Workflow Builder, you can incorporate a number of features and tools into your workflows to help automate your work in Slack. Read on for an overview of what you can build, and how pricing works.

Note: Customers with a dedicated account manager will need to reach out to our Sales team to purchase additional workflow runs.


What to expect

  • With Workflow Builder, you can build standard or premium workflows to help automate routine tasks and processes in Slack. Standard workflows can be run an unlimited number of times without incurring additional charges, while premium workflows run after you’ve reached your plan’s included allotment will be billable.
  • If your workspace is paid for by credit card or self-serve invoice, you can manage additional workflow runs from your billing settings.
  • Members can add Slack steps, connector steps, or custom steps (built by developers in your organization) to their workflows. The steps they choose to include will determine if a workflow is standard or premium.
  • Once a workflow is published, members of your workspace or Enterprise Grid organization (and external people if you’d like) can run workflows from channels, direct messages (DMs), and canvases. Each time a premium workflow is run, it'll count towards your plan’s allotment.

Note: In September 2023, we began migrating legacy workflows to the new version of Workflow Builder that offers standard and premium workflows. If your legacy workflow meets premium workflow criteria, you won’t be charged unless it’s migrated.


Standard and premium workflow usage

Paid Slack plans include unlimited standard workflow runs and an allotment of premium workflow runs. Workflows are considered either standard or premium depending on the types of steps they include.

Standard and premium workflows

  • Standard workflows include Slack steps and up to one connector step.
  • Premium workflows include at least one custom step or two or more connector steps.

Workflow usage

Workflow usage is how many times a workflow is run. The following table outlines the allotments per plan:

Plan Premium workflow runs Cost per additional run
Pro 1,000 runs/month $0.05/run
Business+ 2,000 runs/month $0.05/run
Enterprise Grid* 5,000 runs/month $0.05/run

*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. Following the expiration of the promotional period, Customers that have executed an Order Form for a good faith quantity of the Slack Platform - Additional Premium Workflow Runs will not begin to incur overages (if and as applicable) until after January 31, 2025.

FAQs

When will I start being charged for premium workflow runs?

On November 1, 2023, your premium workflow runs will be reset to zero, and any runs over your plan's allotment will be billed.

How often will I be charged?

Your plan's allotment of premium workflow runs will reset on a monthly basis. If you never exceed your included allotment, you won't be charged. If you exceed the allotment and have authorized additional runs, you'll pay for these when you're charged an outstanding balance for member changes. This means that your amount owed for additional premium workflow runs could accumulate if you're on an annual plan and don't add any new members over the course of a month.

Where can I view and monitor workflow usage?

You can view which of your workflows are standard and which are premium from the workflow dashboard. You’ll be able to track how many times each workflow has been run, and you’ll 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?

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, your members’ access to premium or standard workflows depends on your org-level setting. To learn more, visit Manage Workflow Builder access and permissions.

How do I manage access to connector steps?

If your workspace or org requires app approval, members will see the option to request access to connector steps from the step library in Workflow Builder for owners and admins to approve or deny. To learn more, visit Manage access to connector steps in Workflow Builder.

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 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.
