The officer search GET https://api.companieshouse.gov.uk/search/officers returns officers with both active and resigned directorships.
Navigating from the search to an officers personal appointments GET https://api.companieshouse.gov.uk/officers/{officer_id}/appointments then lists both active and resigned directorships against active and non-active companies (dissolved etc.), ordered by active appointments first.
The web site does offer a filter but we have not made this available through the API but plan todo so soon. Will post on the forum when that functionality is released.
Thanks
