# Proxy Mode

Interacting with BrowserAPI via the proxy mode only changes the access method with our API; apart from that, **full functionality is still available to the end user**. Both costs, parameters and response format remain the same.

{% hint style="success" %}
Note that our **proxy mode supports GET, POST and PUT requests**.
{% endhint %}

### Accessing the API via Proxy Mode

The Proxy Mode is available via:

* HTTPS at **`proxy.webscrapingapi.com:8000`**
* HTTP at **`proxy.webscrapingapi.com:80`**

Authentication via proxy mode is done using the **`username:password`**`@proxy.webscrapingapi.com:8000` method. However, the username part also holds the [parameters](/browser-api/getting-started/api-parameters.md) you want to pass to your request. Hence, the configuration you need to pass to your request is:

* **Username**: **`webscrapingapi`**, followed by the parameters you want to pass to your request (separated by dots)
* **Password**: your personal API key

The most basic URL example for an authenticated request on our API via proxy mode is:

{% code overflow="wrap" %}

```
https://webscrapingapi.<parameter_1.parameter_2. ... .parameter_n>:<YOUR_API_KEY>@proxy.webscrapingapi.com:8000
```

{% endcode %}

### Proxy Mode Requirements and Recommendations

If you decide to use the proxy mode, please make sure you **disable SSL certificates verification** (`-k` switch in `cURL`, `verify=false` in `Python` etc.);

### Proxy Mode Integration Examples
