# Make phone call

**Step 1: Prepare Your Request**

* **Endpoint:** `/call/makeCall`
* **Method:** `POST`
* **URL:** `https://calls.talkstack.ai/call/makeCall`
* **Headers:** Include `Content-Type: application/json`.
* **Authorization:** Bearer token or x-api-key in headers

**Step 2: Construct the JSON Body with Dynamic Variables**

* `agentId`: The id of the agent whose details you want to fetch.
* `projectId`: The id of the project with which the agent is associated.
* `number`: The number you want to make the call to.
* `dynamicVariables`: If your prompt has dynamic variables then you need to pass these variables in this object. For e.g.

**Prompt:**

```
You are an agent called {{name}}. You can take any questions relaetd to 
```

**Request Body:**

```json
{
    "number": "+1XXXXXXXXXX",
    "projectId": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "agentId": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "dynamicVariables": {
        "name": "John"
    }
}
```

**Step 3: Send the Request**

Use your preferred HTTP client to send the POST request with the JSON body.

**Step 4: Handle the request**

The response will provide detailed information about the new project created.

**Success Response:**

* **Status Code:** `200 OK`
* **Body:**

```json
{
    "message": "call made successfully.",
    "status": "success",
    "call": {
        "call_id": "xxxxxxxxxxxxxxxxxxxxxxxxx",
        "to": "+1xxxxxxxxxx",
        "from": "+1xxxxxxxxxx"
    }
}
```

**Troubleshooting**

* `400 Bad Request`: If the `projectId` or `agentId` or `number` is not in the request body.
* `401 Unauthorized`: If the user is unauthorized or the token is missing.
* `500 Internal Server Error`: For errors while getting active agent.
