  • You can switch on the "Persistent stream key" for Facebook Page and Facebook Group. Once you have enabled it, the persistent stream key setting will stay on for the future livestream.

  • You only need to set up the stream key and link for LINE once.

Step 1

Go to the PRISM Live Studio application and click Go Live.



Step 2
