# cPanel API 2 Functions - NVData::set

Warning:
The cPanel API 2 system is deprecated. We **strongly** recommend that you use [UAPI](/cpanel/introduction) instead of cPanel API 2.

## Description

This function creates a non-volatile datastore. The system creates the datastore in the `/home/user/.cpanel/nvdata` directory, where `user` represents the account name.

Warning:
We **strongly** recommend that you use the following [UAPI](/cpanel/introduction/) function instead of this function: - [`Personalization::set`](/specifications/cpanel.openapi/personalization/personalization-set/) — This function saves its data to an NVData file on disk.

## Examples

LiveAPI PHP Class


```undefined syntaxhighlighter-pre
$cpanel = new CPANEL(); // Connect to cPanel - only do this once.

// Set "mymind" NVDatastore to "you"
$cloud_nine = $cpanel->api2(
    'NVData', 'set',
    array(
        'names'  => 'mymind',
        'mymind' => 'you'
    )
);
```

Note:
For more information, read our [Guide to the LiveAPI System](/guides/guide-to-the-liveapi-system/#guide-to-the-liveapi-system).

LiveAPI Perl Module


```undefined syntaxhighlighter-pre
my $cpliveapi = Cpanel::LiveAPI->new(); # Connect to cPanel - only do this once.

# Set "mymind" NVDatastore to "you"
my $cloud_nine = $cpliveapi->api2(
    'NVData', 'set',
    {
        'names'  => 'mymind',
        'mymind' => 'you'
    }
);
```

Note:
For more information, read our [Guide to the LiveAPI System](/guides/guide-to-the-liveapi-system).

cPanel Tag System (deprecated)

Warnings:
- cPanel tags are **deprecated**. We **strongly** recommend that you **only** use the [LiveAPI](/guides/guide-to-the-liveapi-system) system to call the cPanel APIs. Examples are **only** present in order to help developers move from the old cPanel tag system to our [LiveAPI](/guides/guide-to-the-liveapi-system).
- cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
- For more information, read our [Deprecated cPanel Tag Usage](/cpanel-api-2/cpanel-api-2-deprecate-cpanel-tag-usage/) documentation.


Command Line


```undefined syntaxhighlighter-pre

Notes:

- You **must** URI-encode values.
- `username` represents your account-level username.

- For more information and additional output options, read our [Guide to cPanel API 2](/cpanel-api-2/) documentation or run the `cpapi2 --help` command.
- If you run CloudLinux™, you **must** use the full path of the
`cpapi2` command:

```undefined syntaxhighlighter-pre
/usr/local/cpanel/bin/cpapi2
