The base URL in the Messaging Service API on the OpenCloud is incorrect. At the moment it is set as http://apis.roblox.com/messaging-service/ however it should be https://apis.roblox.com/messaging-service/. The issue is that the base URL is currently set as http but it should be https.
This happens in the documentation on any device.
Not sure when this was changed to this however I just checked today while working on a commission with this API.
This is quite a big documentation bug because people will get confused (it took me comparing past code I made from the old documentation to find out the issue):
Repro
Go to the Messaging Service OpenCloud API docs and you will see the incorrect base URL set.
