Messaging between experiences

Help and Feedback Scripting Support
#1

Is there any way to message between experiences?

#2

Cross-Experience Messsages? There is no API that Roblox provided that enables that. You would have to search for a external cloud-based messaging API for that. I am no expert of those, so maybe others can guide you. But to answer your question, no.

#3

I think there’s a way through ProfileService.

I would say check out this tutorial playlist, the second video has an explanation on messages between experiences.
