// Server Side Configuration

import { Server } from "@tokenscript/token-negotiator-server";

const negotiatorServer = new Server({

partnerTag: string, // your socios API partner tag
redirectURI: string, // your socios API application redirect_uri
returnToApplicationURL: string, // re-direct on Oauth2 success
}
}
});

// example redirectURI configuration end point
app.get("/user-login-callback", async (request, response) => {

// retrieve access token
const accessTokenData = await tokenNegotiatorServer.socios.getAccessToken(request.query.code, response);

// set token
tokenNegotiatorServer.utils.setAccessTokenCookie(
response,
'socios',
accessTokenData
);

// navigate back to the application page including the wallet provider details.
