Create a custom profile property in Klaviyo to store the user’s language (e.g., language = en for English). You can pass this from Shopify using Liquid or custom code.

Use this language property in your Klaviyo checkout abandonment flow by adding a trigger filter:

Profile Property: language equals en (for English flow) or any other language code.

Alternatively, if you can’t use profile properties, check the URL (e.g., /en/) in your flow trigger and filter based on the URL structure.

Hello, thank you for your reply.
That's well noted for solution no. 1. 
Concerning the second :

I can't find how to configure a flow filter based on the URL structure.
Thanks

Unfortunately, Klaviyo does not currently offer a direct way to filter flows based on URL structure in the flow trigger conditions.

Workaround:

Instead, you can use the Checkout Started event combined with custom profile properties or UTM parameters that capture the language information.

Steps:

1. Track Language Information:

   • You’ll need to capture the user’s language in a profile property using Shopify's Liquid code or UTM parameters.

   For example, add the following code in your Shopify store (checkout or page load) to capture the language in the profile:

   liquid

   Copy code

   <script> var language = '{{ shop.locale }}'; // Capture language from Shopify _learnq.push(p'identify', { 'language': language }]); </script>

2. Trigger Filter in Klaviyo Flow:

   • Create a flow (e.g., checkout abandonment) in Klaviyo.
   • Add a Trigger Filter based on the custom profile property language, for example:
     • Profile Property: language equals en (for English).
     • Or use language equals fr (for French), etc.

Conclusion:

You cannot filter directly by URL in Klaviyo flows, but by passing the language info to Klaviyo as a profile property, you can target language-specific flows based on that property.

It's very clear, I'm going to try this solution.
Many thanks for your valuable advice.
