We have a new documentation site for cPanel & WHM! You can find our new documentation site at docs.cpanel.net.

We will continue to maintain our API documentation on this server.

  • cPanel API 2 Functions - DiskUsage::buildcache
Skip to end of metadata
Go to start of metadata


This function rebuilds the account's cache of disk space usage data.


We strongly recommend that you use UAPI instead of cPanel API 2. However, no equivalent UAPI function exists.


In cPanel & WHM version 84 and later, when you disable the File Storage role, the system disables this function.




 For more information, read our Calls from the WHM API documentation.

 LiveAPI PHP Class
$cpanel = new CPANEL(); // Connect to cPanel - only do this once.
// Rebuild the disk cache.
$rebuild_cache = $cpanel->api2(
    'DiskUsage', 'buildcache'


For more information, read our Guide to the LiveAPI System.

 LiveAPI Perl Module
my $cpliveapi = Cpanel::LiveAPI->new(); # Connect to cPanel - only do this once.
# Rebuild the disk cache.
my $rebuild_cache = $cpliveapi->api2(
    'DiskUsage', 'buildcache',


For more information, read our Guide to the LiveAPI System.

 cPanel Tag System (deprecated)


  • In cPanel & WHM version 11.30 and later, cPanel tags are deprecated. We strongly recommend that you only use the LiveAPI 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.
  • 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 documentation.

 Command Line
cpapi2 --user=username DiskUsage buildcache

  • You must run the --user=username command.
  • For more information and additional output options, read our Guide to cPanel API 2 documentation or run the cpapi2 --help command.
  • If you run CloudLinux™, you must use the full path of the cpapi2 command:
