Carry a Biqli click ID between trusted websites and checkout domains.
First-party cookies do not automatically move between unrelated domains. Cross-domain attribution adds the current bq_id to links that lead to a trusted receiving hostname.Use it when a visitor moves from www.example.com to checkout.example-payments.com.
In Workspace settings -> Tracking, turn on Outbound domain tracking and
save the configuration. The generated setup prompt then includes the saved
allowed hostnames as outbound destinations.If you configure the SDK manually, pass the receiving hostnames explicitly:
Add the receiving hostname under Allowed hostnames if it will send browser events.
Install the browser SDK on the receiving page.
Let the SDK capture bq_id from the URL.
Confirm getClickId() returns the forwarded value.
Configure only domains you control or trust. The decorated URL exposes the click ID to the receiving site. It never exposes a publishable or secret API key.
