Hi @marken3!

Here is our developer guide on setting up an Abandoned Cart flow for a custom e-commerce website:

Hi @marken3 

Thank you for posting in the Community. I understand, that you are looking to setup a custom integration and a guide to that is available in link that @Brian Turcotte provided. It is however important to mention, that a setup with abandoned carts also would require server-side tracking of Placed orders because you would need the filter on the flow to send out the those, who have actually abandoned their cart. 

Have you already setup up some client side tracking and the Klaviyo.js on your site?

Have a lovely weekend and I look forward to your answer.
