# Update Agent

**Step1: Prepare Your Request**

* **Endpoint:** `/agent`
* **Method:** `PUT`
* **URL:** `https://api.talkstackai.com/agent`
* **Headers:** Include `Content-Type: application/json`.
* **Authorization:** Bearer token or x-api-key in headers

**Step2: Create the Request Body**

* `projectId`: The id of the project in which the agent exists.
* `agentId`: The id of the agent whose details you want to update.
* `name`: If you want to update the name of the agent then add this in the request body.
* `systemInstruction`: If you want to update the systemInstruction of the agent then add this in the request body.

```
{
    "message": "agent data updated successfully.",
    "status": "success",
    "data": {
        "projectId": "XXXXXXXXXXXXXXXXXXXXXXXXX",
        "agentId": "ZZZZZZZZZZZZZZZZZZZZZZZZZZZ",
        "name": "Jack",
        "systemInstruction": "instructions for the agent",
        "voice_id": "xxxxxxxxxxxxxxxxxxxxx"
    }
}
```

**Step 3: Send the Request**

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

**Step 4: Handle the request**

The response will provide detailed information about the agent updated.

**Success Response:**

* **Status Code:** `200 OK`
* **Body:** The response includes details like name, projectId, systemInstruction, id, and phoneNumber.

```
{
    "systemInstruction": "You are Jack. You can take any questions related to astronomy.",
    "name": "Jack",
    "projectId": "XXXXXXXXXXXXXXXXXXXXXX",
    "agentId": "XXXXXXXXXXXXXXXXXXXXXX",
    "voice_id": "EXAVITQu4vr4xnSDxMaL"
}
```

**Troubleshooting**

* `400 Bad Request`: If the `projectId` or `agentId` is missing in the request. Or `name` and `systemInstruction` are missing.
* `404 Not Found`: If the agent is not found.
* `500 Internal Server Error`: For errors in updating the agent details.
