What is SSO?

Single Sign-On (SSO) allows your users to log in to Feedbase using their existing account from your application. This means that your users don’t have to create a new account for Feedbase before they can leave feedback.

​

How does it work?

Here’s a quick overview of how the SSO flow works:

1. Your user clicks on the Login with {Your App} button on your feedbase hub.

2. Feedbase redirects your user to your application’s configured SSO login page. We’ll send along a redirect_to parameter in the query string so that you can redirect your user back to Feedbase after they’ve logged in. E.g. https://yourapp.com/sso/feedbase?redirect_to=https://{slug}.feedbase.app/feedback.

3. Your application authenticates the user and creates a custom JWT token.

4. Your application redirects the user back to Feedbase with the custom JWT token and the redirect_to parameter. E.g. https://{slug}.feedbase.app/api/v1/{slug}/sso?jwt={JWT}&redirect_to=https://feedbase.io/hub/your-hub-id.

5. Feedbase verifies the JWT token, authenticates the user, and redirects them to the redirect_to parameter.

Configuring SSO

​

Create a dedicated SSO login page

The first step is to create a dedicated SSO login page in your application. This page will be used to authenticate your users and create a custom JWT token.

You can use any url for this page, but we recommend using a url like https://yourapp.com/sso/feedbase so that it’s clear that this page is used for Feedbase SSO authentication.

​

Enable the SSO Integration in Feedbase

Once you’ve created your SSO login page, you can enable the SSO integration in Feedbase. You can do this in your Integration Settings by clicking on the Connect button for the Single Sign-On (SSO) integration.

This will open a modal which will ask you to enter the URL of your SSO login page. Enter the URL and copy the JWT Secret that Feedbase generates for you. You’ll need to use this secret to sign the JWT tokens that you generate in your SSO login page.

Finally, click on the Enable button to enable the SSO integration.

​

Authenticate your users and create a JWT token

When users get redirected to your SSO login page, you’ll need to authenticate them with your existing authentication system.

Once you’ve authenticated your users, you’ll need to create a JWT token and redirect them back to Feedbase with the token and the redirect_to parameter.

Here’s an example of how you can do this in Node.js:

import jwt from 'jsonwebtoken';

function createJwtToken(user) {
  const payload = {
    name: user.name,
    email: user.email,
    avatar_url: user.avatar_url, // Optional
  };

  // Do not expose your secret in your client side code!
  return jwt.sign(payload, process.env.FEEDBASE_JWT_SECRET);
}

​

Redirect your users back to Feedbase

Once you’ve created the JWT token, you’ll need to redirect your users back to Feedbase with the token and the redirect_to parameter.

Here’s an example of the redirect URL that you’ll need to use:

https://{slug}.feedbase.app/api/v1/{slug}/sso?jwt={JWT}&redirect_to={Redirect URL}

You’ll need to replace the following placeholders:

• {slug}: The slug of your project.
• {JWT}: The JWT token that you created in the previous step.
• {Redirect URL}: The URL that you want to redirect your users to after they’ve been authenticated.
