Single Sign-On

These are instructions on how to generate Single Sign-On tokens on your server. These token can be used to authenticate your users in our web/mobile widget.

Here's how it works:
- To find your private key, log in above.
  Store your private key on your server and don't share it.
- When a user wants to use the widget, send a request to your server to generate an SSO token.
- On your server, generate a token using the snippet below.
- Pass the token back to your app and into our widget.
- We'll use that token to authenticate your user.
For security reasons, Single Sign-On tokens can't authenticate users who are admin users for other companies. These users will have to log in using https://canny.io/login
1. Install a JWT library
We use JSON Web Tokens to securely authenticate your users. First, install the appropriate JWT library for your server.
Node.js
C#
Go
Java
PHP
Python
Ruby
```
npm install --save jsonwebtoken
```

2. Generate tokens on your server

Node.js

Java

PHP

Python

Ruby

var jwt = require('jsonwebtoken');

var PrivateKey = 'YOUR_PRIVATE_SSO_KEY';

function createCannyToken(user) {
  var userData = {
    avatarURL: user.avatarURL, // optional, but preferred
    email: user.email,
    id: user.id,
    name: user.name,
  };
  return jwt.sign(userData, PrivateKey, {algorithm: 'HS256'});
}

Any field you can specify via identify / our API also works via SSO tokens. Consult this page for a full list of fields.

3. Validate your SSO Token
Paste a sample SSO token in the following input to verify it will work correctly.
