At this point, cPanel’s APIs are not 100% documented.  We are working on it and hope to have complete API docs up in a few months.  I’ve written a CustomEventHandler that will print every API call made into cpanel’s error_log (/usr/local/cpanel/logs/error_log). Installation To use the API Tracer, you will need to download it, then place the Dumper.pm file at /usr/local/cpanel/perl/Dumper and the CustomEventHandler.pm file at /usr/local/cpanel/Cpanel. Once this has been put into the proper location, cPanel …

We have had a flurry of integration tickets over the past week, which is awesome to see.  Most of these tickets have come down to a couple of basic problems.  The first of which is due to some confusion about how to utilize HTTP to call  an API function.The second problem appears to stem from a lack of information API troubleshooting tools that come with cPanel/WHM. The first of our common problems stem from some …

This past week we have been working on documenting how to add icons and groups to cPanel without using our plugin generator.  Writing DynamicUI files is a direct and flexible approach to adding custom groups, icons and extra logic not available through the plugin generator (boolean ExpVar checks, etc).  During the course of documenting this, we realized that we also needed to document the variables available within the cPanel interface.  These are referred to …

Some of the reasons why there hasn’t been many updates lately include our cPanel conference, the cPanel/WHM 11.25.0 release, and the release of the XML-API PHP class 1.0.  If you are not familiar with the XML-API PHP class, it makes interacting with the XML-API much more simple by implementing functions that allow you to call your remote cPanel server without ever having to touch cURL or simplexml.  This works by implementing a function for every …

If you haven’t noticed, we’ve been working on overhauling our development documentation pretty heavily.  We have a ton of great ways to integrate with cPanel but until recently, no information on how to use them.  Starting this week, every week I will be posting about what new articles we’ve added to this documentation along with why you should know about these features. Past couple of weeks I personally have been trying to focus on how …

One of the most flexible ways of working within cPanel is by creating CGI applications.  Of course, this isn’t the most efficient method, however sometimes efficiency isn’t your best bet when you’re in a rush.  You can use a standard CGI script within cPanel, you are limited by our APIs, such as what perl version to use. First thing to note, is that these CGI scripts  have to be placed in /usr/local/cpanel/base/3rdparty/ with normal CGI …

I have been noticing several people challenged with calling cPanel functions via our various ways of hooking into our APIs. Unfortunately, this isn’t as cut and dry as just calling a function within a programming language.  Various factors, such as whether the call is being made from within cPanel or from a remote system, affect how this needs to be done. To help you understand this, I will begin covering these topics in a series …
