An account in Xero can support multiple organizations.
Xero uses OAuth to grant access per organisation.
Authorize access
When you have multiple organizations, you can select from the dropdown in the OAuth access request, to which organisation you want to grant access.
It will also show which organization already has access
Select an organization as a tenant
After granting access, you can select the authorized organization as a "tenant" to access by the integration. Only the authorized organizations will be shown as options.
Authorize additional organizations
To enable another organization, select the "re-authorize" option, which brings you back to the Authorize access step.
