Log into Justworks.
Click on Permissions under Company in the left-hand panel.
NOTE: If you do not see this option or cannot view the page, you are not an Admin and will not have the permissions needed to set up this integration. Please find a user in your organization with the right permissions.
You'll see a screen that lists all Admin permissions. Click into the specific permissions needed to ensure you have them (a list of approved users will pop up for each permission).
