On this page [https://digital.nhs.uk/developer/api-catalogue/organisation-data-terminology#get-/OrganizationAffiliation](https://digital.nhs.uk/developer/api-catalogue/organisation-data-terminology#get-/OrganizationAffiliation)

the parameter `primay-organisation` is spelt using English spelling which the API doesn’t accept. It requires US spelling, `primary-organization`
