Only one endpoint(to get temp tokens) for multiple users(clients), possible or not?

in Development
I am developer and I want to integrate lightspeed shops into my application.
1. Does I must provide unique endpoint(redirectURI to get temp token) for each client(store) separately or I can use one for all clients(store)?
2. Can I request a new token(via refresh token) even though the current token has not expired?
Thank in advance!

1. Yes you need to provide that url to set the scope and get the access grant to get the temp code for that account.
2. You can but if it hasn't expired it will return the same token
