Umami across subdomains

[pwbriggs]

I'm having trouble setting up Umami with subdomains. Here's my scenario:

At mydomain.com, I serve my product website that advertises my service. This site includes my marketing content and ad landing pages, etc. However, serve my actual webapp over at app.mydomain.com. I want to track users across the boundary between my app and my website, so they both use the same website ID for Umami.

As far as I can tell, though, Umami doesn't differentiate between https://mydomain.com/ and https://app.mydomain.com/—they both come out as /.

What am I missing here? Do I need to create a custom tracker function for this usecase, sending a custom value for url that includes the subdomain? Or is this an unsupported setup?

Thanks! ❤️

I'm also interested in learning what the best practice is for this.

You can filter the dashboards by hostname, but it seems sessions are not tracked across subdomains with the same websiteID.

SessionID includes hostname taken from window.location.hostname so each subdomain will be a separate session.

umami/src/lib/session.ts

Line 42 in d8e46e4

const sessionId = uuid(websiteId, hostname, ip, userAgent);

Right, @3nth, so that means we can't currently use things like the funnel report for this setup.

I ended up having to work around this by restructuring my whole site. 😞
