If you visit your dashboard, on the top of the page, you will see two tabs: Projects and Organizations. There are related but different concepts, and this short section will help you understand when to utilize each.
You can think of a project as a scoped configuration for a single implementation. Each project comes with both a sandbox and live mode, which each have their own environment ID and configuration.Importantly, if a user is invited as a member of an organization, they will have access to all projects within that organization.
In the navigation bar, click on the Organization dropdown menu (first on the left):
Click “Create organization” at the bottom of the dropdown
Enter Organization Name and Website URL
And you’re done. You now have a new organization that you can use. You will need
to invite members of your team to this organization if you would like to work
with them there.
