# Update Agent Config

> Merge top-level keys into an agent's behavior config. Existing keys are preserved unless `replace` is explicitly true. This does not change prompts, stages, fields, or channel prompts.

Merge behavior settings into an agent's `config` object without changing prompts, stages, fields, or channel prompts.

By default, only the submitted top-level keys change and every other config key remains intact. Use `replace: true` only when you intentionally need to replace the complete object.

Common settings include `disabled_channels`, `first_contact_channel`, `email_sender_id`, and `gate_outbound_to_hours`.
