Prestashop web service

Hi, guys, I need your help. I’m working with prestashop services.
My problem is I can not do POST through the apis.

If I can access the rude type of GET.

I’m testing the post with the postman tool
This is my route

This is the xml I am sending.

<? Xml version = "1.0" encoding = "UTF-8"?> paco hernandez

Your url is not working
