I have an online store created in prestashop (Version 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?

Hi @Onlysilver 


If you’ve ensured that the webservice key, automatically generated by Klaviyo’s module, already has the proper permissions then this could indicate you need to add a rewrite rule to your server’s .htaccess file. If your server runs PHP via CGI or FPM (you can check with your hosting provider) you’ll likely need to add the following two lines so that Klaviyo’s authentication headers get passed along to PrestaShop.

The lines to add to your server’s .htaccess file are:

RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule . - [E=HTTP_AUTHORIZATION:%1]

Let us know if this doesn’t resolve the issue for you.

Hey @Dpm,


It looks like you wrote in about this in another post. My colleague provided a response on troubleshooting steps that you can follow in that other thread. If you haven’t had a chance to check it out, here’s his update for you:


Thanks very much for being a member of Klaviyo’s Community Forum!





Hy @Scott,

Thank you! Solved my problem.


Pues yo he copiado y pegado las dos líneas de código al final del archivo .htaccess pero el problema continua.

Uso Prestashop
