Multi-tenant

  • instance: "crm::acme" works on the database of the tenant acme of the multi-tenant instance crm.
  • With instance: "crm", the call works on the database of the tenant of the request: a custom API called with the x-am-tenant-username header passes it on to the APIs it calls. A request without a tenant works on the structure database.
