Step 9: Authenticated Joining Process for Learners

For learners, you need to add a Join Session button on your LMS for the sessions they are supposed to join

• For each learner, the redirection URL should be created as and when they press the button. The URL for each learner will be unique and shortlived (max expiry 1min)

• When a learner presses the Join Session button, redirect them to the following URL —

  • https://excelr.onlineclass.site/identity-based-login?jwtToken={user_JWT_token_via_SSO}&redirectionUrl=/meeting/join/{class_id}

  • In this URL, you need{user_JWT_token_via_SSO} which is the unique JWT-based login token for the learner, using the code mentioned below

  • For generating this URL, you need{user_JWT_token_via_SSO} which is the unique JWT-based login token for the student. You need to refer to the SSO integration document 🔗 for this

    // nodejs snippet
    jwt = require('jsonwebtoken')
    moment = require('moment')
    
    jwtTokenSecret = "<JWT Token secret shared by Wise>" // This SHOULD BE secret*
    
    // Redirect URL generation function on backend
    function generateJWTtoken(vendorUserId, profile, name) {
    	const payload = {
    		vendorUserId: vendorUserId, 
    		profile: profile, 
    		name: name, 
    		exp: moment().add(1, 'm').unix() 
    	}
    	const jwtToken = jwt.sign(payload, jwtTokenSecret)
    	return jwtToken
    }
    
    // Calling the function inside API to sign into Wise: 
    const user = { vendorUserId: "xyz_abc", "name": "Sam Sharma" }
    // User identified, authenticated by you in your system & fetched from your DB
    const user_jwt_token = generateJWTtoken(user.vendorUserId, user.name, "student")
