 cPanel Tag System (deprecated)


Warnings:

  • 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 Cron edit_line linekey=c5e242023f60e1bd37110687338e9e8d command=%2Fusr%2Fbin%2Fperl%2Fhome%2Fusername%2Fhappynewyear.pl day=1 hour=0 minute=0 month=1 weekday=*


Notes:

  • You must URI-encode values.
  • username represents your account-level username.
  • 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:

    /usr/local/cpanel/bin/cpapi2
