Best way to log API calls that create records

If you have access to core code you can add logging to ~/include/api/RestService.php just below the comment that has "// This looks like the post contents are JSON".

Something like:

                    // This looks like the post contents are JSON
                    // Note: If we want to support rest based XML, we will need to change this

@$GLOBALS['log']->fatal("POSTED DATA:$postContents");

Add extra code to filter out unwanted requests based on $this->getRequest()->getRequestURI().

If it is sugarondemand then you may be able to create a ~/custom/include/api/RestService.php, derive from the core code RestService and override getRequestArgs(). I've not tried that though.

 ~/custom/include/RestService.php ist an add-on file wich is called before the REST service functions are executed.

Code of ~/api/rest.php:

ob_start();
chdir(dirname(__FILE__).'/../');
define('ENTRY_POINT_TYPE', 'api');
require('include/entryPoint.php');
SugarAutoLoader::load('custom/include/RestService.php');
$restServiceClass = SugarAutoLoader::customClass('RestService');

global $service;
$service = new $restServiceClass();
$service->execute()

So you can add logging of incoming data to such a custom file without touching the core files.

Oh I like this idea, might work better than the logic hook.
