Hi,
You'll have a hard time doing that as the link to do that requires a session token to be valid for security reasons (in order to avoid XSS attacks). The link is:
../administrator/index.php?option=com_hikashop&tmpl=component&ctrl=toggle&935fb622b66fc187b4f931714f34a15a=1&task=product_published-1&value=0&table=product
where 935fb622b66fc187b4f931714f34a15a is the session token, the 1 after product_published- is the product id and the 0 is the state your want (0 for disabled, 1 for enabled).
It would be best to implement a small system plugin and run yourself the query to change that from within the plugin based on the parameter of the $_REQUEST in an onAfterRoute trigger.
