# Get phone number data

**Step 1: Prepare Your Request**

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

**Step 2: Construct Request Body**

You can get phone numbers using phoneNumberId, agentId, and projectId. You can only use one of these in each request if more than one are passed then the precedence order is: \
**phoneNumberId -> agentId -> projectId**

* `phoneNumberId`: This is the ID of the phone number you are inquiring about..
* `agentId`: This is the agent ID linked to the phone number you are inquiring about.
* `projectId`: This is the project ID linked to the phone number(s) you are inquiring about.

**Step 3: Send the Request**

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

**Step 4: Handle the Response**

The response will provide detailed information about the phone number associated with the given identifier.

**Success Response:**

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

```
{
    "message": "Phone number details fetched successfully.",
    "status": "error",
    "data": {
        "e164": "+14152148508",
        "id": "3189fbff-f9fa-4920-b95c-63387b1204a4",
        "status": "AVAILABLE",
        "projectId": "94f53ecd-ec99-42fc-bc69-e79468550af2",
        "agentId": "232ac42a-2ea0-4276-a5d8-43c8c9f7b857"
    }
}
```

* Confirm that the `projectId` is correctly included in the request body.
* Ensure that the `agentId` is valid and corresponds to the phone number searched for.
