Prestashop lite speed cache via webservice doesn´t flush

#1
We have a prestashop 1.7.6.0 and lite speed server and plug in lite speed for prestashop.

If we make changes (like change stock or change stock status) inside prestashop backoffice or if clients makes orders in our website, prestashop lite server cache works just fine, it refreshes that page on our website but if those changes are made via webservice (we have an erp that connects to prestahop via webservice) then doesn´t flush our cache automatically, sometimes takes minutes and sometimes takes hours, and it is driving us crazy.

Any ideas?
