# Parameters

Parameters can be set either through the Dashboard or manually.

1. **Setting in the Dashboard**: Go to the "Proxy Configuration" section on the plan page to specify the desired parameters for your requests.
2. **Manual Configuration**: You can add parameters directly after your login information using the delimiter “\_\_”. \
   Each key and its values should be separated by a dot, and a semicolon should separate different parameters.

The format should look like this: `key1.value1,value2;key2.value1,value2`.

**For example:**

If you want to select **Germany** as the country, your code would look like this:

```bash
curl -x "http://login__cr.de:password@gw.dataimpulse.com:823" https://api.ipify.org/
```

If you want to select **two countries**, such as Germany and Australia, use the following code:

```bash
curl -x "http://login__cr.de,au:password@gw.dataimpulse.com:823" https://api.ipify.org/
```
