+### Set organization properties at creation
+
+Pass additional properties when you create an organization to give it a slug, map it to your own system, or brand its hosted pages. Every property except the display name is optional.
+
+| Property | Description |
+|---|---|
+| `display_name` | Human-readable name shown in the dashboard and hosted UI. Required. |
+| `slug` | DNS-safe identifier such as `orion` or `auth.orion-analytics.com`. Expands `{{org_slug}}` in [template redirect URLs](/guides/dashboard/org-redirect-urls/). |
+| `external_id` | Your own identifier for the organization, so you can look it up by your system's ID. |
+| `logo_url` | Publicly accessible logo URL shown on [branded login pages and portals](/fsa/guides/organization-branding/). |

+A `slug` gives each organization a DNS-safe identifier that expands `{{org_slug}}` in [template redirect URLs](/guides/dashboard/org-redirect-urls/). You can also set or change it later with `updateOrganization`.

 Next, let's look at how users can be added to organizations.
