Hi Ton,
As Richard as pointed out, we have a wrapper template for the Chilkat Communications library, this also has an online utility that allows you to post CURL commands to it, and it informs you what code to write.
But… what might be of interest to you is we are currently adding a WooCommerce dedicated Task Class to our Chilkat wrapper template - this will be automatically included in future updates of our product.
An example of the current offering is available via our web site - https://noyantis.com/product/chilkat/
Any questions, feel free to email / call or pop in to the Monday / Wednesday webinars.
Thanks,
Andy
