  assignments = response.json()
  for a in assignments:
      scope = a.get("facility_id") or "organization-level"
      print(f"{a['data_owner_email']} → {scope}")
  ```

  ```javascript JavaScript theme={"theme":{"light":"github-light","dark":"github-dark"}}
  const axios = require('axios');

  const headers = {

  axios.get(`https://api.dcycle.io/v1/custom-kpi-datasets/${datasetId}/assignments`, { headers })
    .then(response => {
      response.data.forEach(a => console.log(`${a.data_owner_email}`));
