Organization ID

In Zoho Billing, your business is termed as an organization. If you have multiple businesses, you simply set each of those up as an individual organization. Each organization is an independent Zoho Billing Organization with it’s own organization ID, base currency, time zone, language, customers, reports, etc.

The header X-com-zoho-subscriptions-organizationid along with the organization ID should be sent in with every API request to identify the organization.

The organization_id can be obtained from the GET /organizations API’s JSON response.
oauthscope : ZohoSubscriptions.settings.READ
Alternatively, it can be obtained from the Manage Organizations page in the admin console:

Login to the Zoho billing admin console. Click the drop down with organization’s name as the label and click Manage Organizations.
