Context

We offer an excellent feature to do cross domain tracking, learn more in this faq

This feature works automatically in most cases, by updating the links in the DOM and adding the parameter &pk_vid=xyz to all links going to the other known domains.

But in some cases, the links are not standard links, or are built by some complex javascript, and our Cross domain feature will not catch these non standard links.

Proposed Solution

To make it possible to use cross domain tracking even in a complex app/website that has dynamic links, then

• we need to provide a new JavaScript tracker method that users will be able to call to get the value &pk_vid=xyz which they can then manually append to their cross-domain links.
• Maybe the method could be called getCrossDomainLinkingUrlParameter or so?
• The new method needs to be covered by JS tests
• and documented in our reference here: https://developer.matomo.org/api-reference/tracking-javascript
• we also need to add a little note in our cross domain FAQ here: https://matomo.org/faq/how-to/faq_23654/
