Can someone point me in the right direction regarding how I can authenticate requests between the React frontend and Laravel 5 backend? Do I need to implement the App Bridge? Do I have to upgrade Laravel to a newer version?
Thanks in advance. I'll be happy to clarify if needed.
If the app is embedded, you should use session tokens to authenticate and App Bridge can help with that. Check out the getting started section here. I am not a php dev, so I'm not sure what the major changes are since Laravel v5, but I don't believe it matters what the backend is, as long as you can implement the necessary callback routes and decode the session token. We also have a php library that helps with just that.
