01/31/2023, 4:06 PMOn the front end I can use Javascript - not a problem - and then pass the User ID to the Rails app

01/31/2023, 4:07 PMBut am I OK setting up, say a Node backend server - getting the JS to talk to this
rahoulb
01/31/2023, 4:07 PMAnd then my Rails app taking that User ID and just calling the Core server to verify it and get details

01/31/2023, 4:08 PMthe JS on the frontend can call the rails backend with the JWT which the rails backend can verify

01/31/2023, 4:08 PMIt looks like CDI's GET /recipe/user with the ID will do it
rahoulb
01/31/2023, 4:08 PMAah OK - cheers

rahoulb
01/31/2023, 4:09 PMIf so, I will probably build a Rails engine that implements it, so people can embed it directly into their Rails app

01/31/2023, 4:12 PMwell.. the backend SDK does a lot of things and it's not just a pass through

rahoulb
01/31/2023, 4:15 PMOK - I'll hold off on that one till I've looked through the other backend source (getting overexcited!)
rahoulb
01/31/2023, 4:15 PMFound it - so it's the fronttoken header - send that to Rails, which can decode it and it then knows who the user is

01/31/2023, 4:16 PMPerfect!

01/31/2023, 4:37 PMIt’s not the front token. Id suggest that you see our docs for using session with JWT.
