### Answer To reference what a customer said in a conversation flow node, you can use dynamic variables with the

{{variable_name}}

syntax. [(1) ]() Dynamic variables work in several places within your conversation flow: - Prompts (agent instructions and personality) - Begin message (opening greeting) - Tool configurations (custom function URLs, tool descriptions, property descriptions) - Call handling (voicemail prompts and messages, transfer call phone numbers, warm transfer instructions) To add dynamic variables in your prompts: 1. Type

{{

where you want a variable - a dropdown will open listing available variables 2. Filter the list by typing more characters after

{{

3. Choose a variable with Enter, a click, or Tab For example, you can create personalized responses like: - "I see you're calling about order `{{order_id}}`" - "Hello

{{customer_name}}

, thanks for calling!" You can also set agent-level default dynamic variables as fallback values that will be used when specific variables aren't included in the call request.
