Hey @dilanx 

Enabling onsite tracking is different for each ecommerce integration.

You do not need to add Klaviyo.js separately if you enabled active onsite tracking through one of the ecommerce integrations below:

• Shopify
  Active on Site tracking is added automatically through the integration or through the Klaviyo app embed if it's toggled on.
• BigCommerce
  Active on Site tracking is added when you integrate if you also check the setting Automatically add Klaviyo onsite JavaScript in Klaviyo.
• WooCommerce
  Active on Site tracking is added automatically when you integrate.
• Magento
  Active on Site tracking is added automatically when you integrate.
• Wix 
  Active on Site tracking is added when you integrate if you also check the setting Automatically add Klaviyo onsite JavaScript in Klaviyo.

If you are using another ecommerce platform, or a custom platform, you can install Klaviyo.js manually.

I hope this helps

I'm trying to trigger a flow without having a store.

Is it possible for me to trigger the flow for Active on Site, using just an API call? 

Basically I want to test my flows without having to actually trigger them as a customer.
