Hephaistos20 v0.2.3
This extension allows Hephaistos for Starfinder and Roll20 (with Starfinder template installed) to connect.
This has a very similar functionality to Beyond20, but for Starfinder.
When you roll on your Hephaistos character sheet, it should send it straight into the Roll20 chat.
If it is not working or you get an error, refresh the Roll20 and Hephaistos webpages.
