Integration Notes

  • City and County of Denver uses the Accela Citizen Access portal. Multiple cities share this platform, so include the jurisdiction=aca:denver parameter to avoid HTTP 300 disambiguation responses.
  • Permit data is cached for 4 hours. The data_freshness object in every response shows when the data was last fetched from the portal.
  • Pro and Enterprise plans can use force_refresh=true to bypass the cache and fetch live data.
