I have an online store created in prestashop (Version 220.127.116.11). The server works with Plesk in its latest version with Php 7.3.
I have installed the free Klaviyo module and I have configured it following the manual. Everything worked correctly until I got to the API integration.
When I integrate Klaviyo with Prestashop, I add the address of the online store, the Prestashop Webservice API and permissions are correct.
I click on "Click here to retrieve the list of shops" but I get the following error: Please make sure your webservice key has permissions to the 'klaviyo' resource.
I have tried with another server but the problem persists, could you please advise me?
