# Set up post-call analysis categories

> Set up Retell post-call analysis to extract structured insights from every call — text, selector, boolean, and number categories evaluated by an LLM.

## Overview

Post-call analysis is a feature that allows you to analyze calls after they have ended. We provide several built-in analysis categories, and you can also customize your own.

## Step 1: Create an Analysis Category

In the dashboard, navigate to the "Post-Call Analysis" tab to create a new analysis category.

We offer four types of analysis categories:

1. Text
2. Selector
3. Boolean
4. Number

### Examples

1. If you find the default agent call summary doesn't satisfy your needs, you can create a new analysis category with type `Text` and name it "detailed\_call\_summary".
   * **Description**: "Provide a detailed summary of the call so that when the call is transferred, the new human agent has the full context."
   * **Format Example**: Provide an example of how the output of this analysis category should look.

2. To analyze whether the customer is a new or existing customer, create a new analysis category with type `Boolean` and name it "is\_new\_customer".
   * **Description**: "Indicates whether the customer is new or existing."
   * **Format Example**: Provide an example of how the output of this analysis category should look.

3. To determine if the customer was transferred to a human agent, create a new analysis category with type `Boolean` and name it "is\_transferred".
   * **Description**: "Indicates whether the call was transferred to a human agent."
   * **Format Example**: Provide an example of how the output of this analysis category should look.

4. To analyze the transaction amount for the customer, create a new analysis category with type `Number` and name it "transaction\_amount".
   * **Description**: "The transaction amount for the customer."
   * **Format Example**: Provide an example of how the output of this analysis category should look.

## Step 2: Consume the Analysis Result

### Method 1: Dashboard History Tab

You can view the analysis results in the dashboard history tab.

### Method 2: Webhook

The webhook will be triggered when the call ends, and the payload will contain the analysis results.

### Method 3: Get Call API

You can also use the [Get Call API](/api-references/get-call) to retrieve the analysis results.
