Passing Session Data for Better Attribution
﻿
For Weberlo’s attribution to work optimally, you need to capture the w_session_id from the website’s dataLayer and pass it to your backend. Then, send this value back to Weberlo’s Transaction Endpoint as the session_id field.
w_session_id helps stitch front-end and back-end data together.
It ensures accurate attribution, linking conversions back to the correct marketing source.
Without it, conversions may not be properly attributed to the original traffic source.
