I'm trying to get certain sections of a website such as contact form interact with a CRM. Are there any built-in helpers/tools in C5 that make it easier to do this or do I have to rely on PHP SOAP (http://www.php.net/manual/en/book.soap.php) and custom build the functionality to do this? I have never tried anything like this with C5 and this could be a big task. I would appreciate pointers on how to get started and any known issues that I need to be aware of.
