GET https://harvest.greenhouse.io/v1/demographics/questions to list all configured EEOC demographic questions and their question_set_id and answer option ids.
GET https://harvest.greenhouse.io/v1/applications/:application_id/demographics/answers to retrieve the candidate's existing EEOC responses for a given application.
To write or update answers, POST to https://harvest.greenhouse.io/v1/applications/:application_id/demographics/answers with a JSON body containing an array of answer objects, each with a question_id and answer_option_id.
To delete an existing answer, send DELETE to https://harvest.greenhouse.io/v1/applications/:application_id/demographics/answers/:answer_id.
Confirm the stored answers by re-fetching GET /v1/applications/:application_id/demographics/answers.
Ensure your API credential has the 'Can see EEOC data' permission in Greenhouse; without it, demographic endpoints return 403.
Known gotchas
EEOC demographic data access requires explicit permission on the API key; standard Harvest credentials do not include this by default.
Answer option IDs are specific to your Greenhouse account's question configuration and are not portable across accounts; always fetch the question list first.
Posting a new answer for a question that already has an answer does not update it — you must DELETE the existing answer first, then POST the replacement.
