# Using Smart Proxy Manager with Splash

> [!WARNING]
> For the code below to work you must first [install the Zyte
> CA certificate](../../misc/ca.md#ca).

> [!NOTE]
> All the code in this documentation has been tested with Splash 3.5, Python 3.9.5

## Installation

1. Setup the Zyte SmartProxy (formerly Crawlera) Headless Proxy as described in spm-headless.
2. Download and install Splash following this guide as explained here: [https://splash.readthedocs.io/en/stable/install.html](https://splash.readthedocs.io/en/stable/install.html)

Assuming you installed Splash using Docker, proceed to run Splash with:

```
docker run -it -p 8050:8050 --rm scrapinghub/splash
```

You can confirm Splash is running by accessing the Splash web UI at [http://localhost:8050](http://localhost:8050)

## Using Web UI

Here is a sample script you can use to test the integration of Splash with Smart Proxy Manager, once you have also installed the Headless Proxy.

Just paste this code into Splash web UI main page, enter a URL (ex. [http://example.com](http://example.com)) and hit the
“Render me!” button.

```lua
function main(splash)
    splash:on_request(function (request)
        request:set_proxy{"host.docker.internal", 3128}
    end)

    splash:go(splash.args.url)
    return splash:png()
end
```

## Using Python & Request library

In order to use Python and Request library with Splash we need to first take the lua code mentioned
above and save it in a file name say spm-splash.lua. Now, save the Python code mentioned below to
another file in the same directory say sample.py. Make sure you have
[Requests](https://2.python-requests.org/en/latest/) library installed before moving ahead.

```python
import requests

splash_server = 'http://0.0.0.0:8050'
url = "https://example.com"

with open('spm-splash.lua') as lua:
    lua_source = ''.join(lua.readlines())
    splash_url = '{}/execute'.format(splash_server)
    r = requests.post(
        splash_url,
        json={
            'lua_source': lua_source,
            'url': url,
        },
        timeout=100,
    )

    fp = open("spm-splash.png", "wb")
    fp.write(r.content)
    fp.close()
```

Now run the file using:

```
$ python sample.py
```

You’ll find a screenshot of entered URL in the same directory as your Lua and Python files.
