Hi,

we’re in the process of converting some of our services into flows and ran into an issue: our “Send email” action nodes include a link to the app in the message body, which relies on the hostname built-in service variable. This doesn’t seem to behave the same way in flows.

Is there a recommended way to handle this, or is creating an action variable and manually assigning the hostname value based on the active environment, or using an environment-specific secret as a flow param, the intended approach?
