Go to the agent detail page and click the **Post-Call Analysis** tab. Select the type that fits your data: **Boolean** — Yes/no determinations ``` Name: user_reached Description: Was the user reached? Set to false if voicemail is detected, if only asked for reason of call, or if only asked to leave a message. Otherwise set to true. ``` **Text** — Detailed textual extraction ``` Name: detailed_call_summary Description: Provide a detailed summary so that when the call is transferred, the new agent has full context. Format example: "Customer called about billing issue. Resolved by explaining recent price changes. Follow-up needed in 2 weeks." ``` **Number** — Numerical value extraction ``` Name: purchase_intent_amount Description: Extract the dollar amount the customer is interested in spending. ``` **Selector** — Categorize from predefined options ``` Name: issue_category Description: Categorize the main reason for the call. Explain each choice in this description field. Choices: ["Technical Support", "Billing Question", "Sales Inquiry", "Product Information"] ``` Write explanations for choices inside the **description** field. The choices list should contain only the choice labels themselves.
