# Tools

> Learn how to create tools for your agents

Tools extend your agents' capabilities by enabling them to perform actions and produce structured outputs. There are two types of tools available:

* **Webhook tools** — Call external APIs or services to perform actions
* **Structured output tools** — Extract information from conversations in a defined format

## Navigate to tools

From the sidebar, click **Tools** to view and manage your tools.

## Webhook tools

Webhook tools allow agents to call external APIs or services to perform actions like sending notifications or querying databases.

### Create a webhook tool

### Configure the tool

Provide the following details:

**Name and Description**

Add a descriptive name and explain when the agent should call this tool.

**Request Configuration**

* **Method** — Select HTTP method (GET, POST, PUT, PATCH, DELETE)
* **URL** — The webhook endpoint URL

**Headers** (Optional)

Define headers to include in the request.

**Query Parameters** (Optional)

Define parameters the LLM will collect and send as query strings.

**Body Parameters** (Optional)

Define the request body structure with a description and properties the LLM should collect.

Click **Add tool** to save.

## Structured output tools

Structured output tools enable agents to extract information from conversations in a defined format, such as user names or order details.

### Create a structured output tool

Click **Add structured output tool** to open the configuration panel.

</Frame>

### Configure the tool

Provide the following details:

**Name and Description**

Add a descriptive name and explain when the agent should call this tool.

**Parameters**

Define the structure of data the agent should extract.

For each parameter, specify:

* **Data type** — Boolean, Integer, Number, String, Object, or Array
* **Name** — The parameter identifier
* **Required** — Whether this field is mandatory
* **Description** — Detailed guidance for the LLM on what this parameter represents

Click **Add param** to add more parameters. Click **Add tool** to save.

## Inbuilt tools

Some tools are built into the platform and enabled by default:

| Tool                 | Description                      |
| -------------------- | -------------------------------- |
| **End conversation** | Allows the agent to end the call |
