Sending extraParams to Hosted Login Page from SPA SDK

[calqulate]

Hello, I’m trying to send extra config parameters to my custom designed (using auth0.js SDK) hosted login page. I’m trying to send these parameters from my React app that uses the SPA SDK when calling loginWithRedirect and read it on the hosted login page using config.extraParams.

I read that I should not use login_hint anymore. How can I do this?

Passing initialScreen to Lock from auth0-spa-js

Turns out it was super easy - I can pass any extra parameters to loginWithRedirect and they will end up on the authorize URL string as url-encoded parameters. loginWithRedirect({ mode: 'signUp' }); …and in the custom login page: // retrieve screen mode from extra params if sent; default to 'login' var mode = config.extraParams.mode || 'login'; ... var lock = new Auth0Lock(config.clientID, config.auth0Domain, { auth: { // ... }, // add a selector for which screen to put up initialScr…
