Everything else derives from it: table columns, contact-page fields, form questions, trigger conditions and message variables. Mark a field "use as variable" and `[yourfield]` resolves in every template. Trigger categories are managed here too; each category becomes a sidebar tab. ## Contact owners The contact owners table with working hours and default calling agents Owners are your reps. Per owner you set: * **Working hours**, which gate automated WhatsApp sends for their contacts * **WhatsApp number**, the personal line their messages send from * **Default calling agent**, so calls to their leads use the right voice and number * **Language**, which drives template language matching for their audience ## Numbers and agents (Settings, Accounts) The Accounts area stacks your phone numbers and AI calling agents. Numbers carry their connection type (Evolution API or WhatsApp Business API) and pacing settings; agents carry voice, script, calling hours and their pinned outbound number. ## Connections and alerts (Settings) API credentials live in Settings: WhatsApp connections, the HubSpot token, email senders. Sync failures raise a bell notification for admins, with an optional per-admin email alert. Theming is also here: light, dark, or automatic by local sunrise and sunset. Nudge autosaves everywhere.
