@tiny-lamp6590 yes, I believe you do need your own back end for token exchange.
I've now written my own, there are some gotcha's when using the React SDK with your custom built auth server. You have to ensure that you drop the following cookie:
app.at_exp - otherwise you isAuthenticated will show as false.
Just reviewing how to integrate FusionAuth within an existing codebase and architecture. It appears from the following:
https://github.com/FusionAuth/fusionauth-example-react
That one would need a separate "identity" server to manage communication between any React front ends and FusionAuth is this correct?
Am I correct is saying that there is no way to directly integrate the React SDK directly to the FusionAuth server?
