Advanced settings configure the tools available to the agent, the calls it transfers and its speech fine-tuning. They are read with Get AI Agent Advanced Settings and changed with Update AI Agent Advanced Settings.
The Get request returns every setting as a field descriptor, grouped in tools, transfer_call and fine_tuning. Each descriptor reports the setting label, type, suggested component, default, description and current value, plus min/max for numeric settings, options for lists, conditional for the settings that only apply when another setting holds a given value, and formFields for the extra values a toggle enables.
The Update request body is flat: two objects, tools and fine_tuning, holding the setting values only, plus the optional routes list. The extra values a toggle enables (scheduleLink, red_alert_webhook_url, office_noise_url, ...) are submitted next to that toggle, in the same object.
