# Fetching HTTPS pages with Zyte Smart Proxy Manager

Zyte Smart Proxy Manager (formerly Crawlera) performs HTTPS requests using [CONNECT method](https://tools.ietf.org/html/rfc7231#section-4.3.6), transparently tunneling packets over
default HTTPS port 443 to and from the destination server in a secure session.

To fetch HTTPS web pages through Smart Proxy Manager you may need to
[download and install the Zyte CA certificate](../../misc/ca.md#ca). You can use `curl`
to check that the installed Zyte CA certificate is working:

```bash
curl -vx https://proxy.zyte.com:8014 -U <API key>: --cacert zyte-ca.crt https://httpbin.org/ip
```

Alternatively, you can disable SSL certificate verification in your HTTP
client.
