Here's a sample workflow you can implement on Slack. This example involves asking new channel members to fill out a form and collecting their submissions into a list. Please note that this is a basic workflow with only a few steps. You can create more complex workflows with additional steps and integrate with third-party applications as needed.

1. Click "Apps"

2. Click Manage

3. Click Browse Apps

4. Click "Workflows"

5. Click "Create a Workflow"

6. Click "Choose an event" to start the workflow

7. On the right hand side, click on “when a person joins a channel”

8. Click channels:

9. Select the channel you want

11. Click continue

12. Click "Add steps"

13. Click "Messages"

14. Click “send a message to a channel”:

15. Select a channel where you want to send the message

16. Click "Add a message"

17. Type the message you would like to send

18. Click "Include a button."

22. Click on “collect info in a form”

23. Rename the form

24. Click "Add Question"

31. Select the list you’d like to put the responses in

32. Click "Save"

33. Once you’re done with all the steps of the workflow you’re building, you can select “finish up”
