Each Hologram organization has a unique numerical identifier called an organization ID (ORGID). If you are using the REST API, you will likely use your organization ID in the request URL or body.
You can find your organization ID in two places in your dashboard.
Click the Organization drop-down in the top right corner.
Your organization ID displays below your organization's name.
You can also open the Settings section from the main menu and view your organization ID on the This organization page.
