Node Library
To authenticate and use your app with the IDPartner API, install the node-idpartner node module.
To create an OAuth Confidential Client using the IDPartner APIs we created a node module which makes it easy to get going quickly.
To install the module using NPM:
npm install @idpartner/node-oidc-client
Or Yarn:
yarn add @idpartner/node-oidc-client
Include the
@idpartner/node-oidc-client module within your script and instantiate it with a config:const IDPartner = require('@idpartner/node-oidc-client');
const rawJWKS = fs.readFileSync('jwks.json');
const jwks = JSON.parse(rawJWKS);
const idPartner = new IDPartner({
jwks,
client_id: '128ecf542a35ac5270a87dc740918404',
callback: 'https://myapplication.com/auth/callback',
});
For example:
const jose = require('node-jose');
const keyStore = jose.JWK.createKeyStore();
keyStore.generate('RSA', 2048, { alg: 'RSA-OAEP', enc: 'A256CBC-HS512', use: 'enc' }));
keyStore.generate('RSA', 2048, { alg: 'PS256', use: 'sig' }));
const JWKS = keyStore.toJSON(true);
Instantiating a IDPartner instance without a config object will result in an error
Set up your IDPartner as above and pass the following configuration options in:
{
client_id: 'Your application's client ID',
callback: 'The location you want the app to return to on success',
jwks: 'Private/public keys used to verify and decrypt any JSON Web Token (JWT) issued by the identity provider authorization server
}
const express = require('express'),
router = express.Router(),
IDPartner = require('@idpartner/node-oidc-client');
const rawJWKS = fs.readFileSync('jwks.json');
const jwks = JSON.parse(rawJWKS);
const idPartner = new IDPartner({
jwks,
client_id: 'mXzJ0TJEbWQb2A8s1z6gq',
callback: 'https://myapplication.com/auth/callback',
});
router.get('/jwks', (req, res, next) => {
const jwks = await idPartner.getPublicJWKs();
res.send(jwks);
});
router.get('/auth', (req, res, next) => {
const scope = ['openid', 'email', 'profile'];
req.session.idp_proofs = idPartner.generateProofs();
const authorizationUrl = await idPartner.getAuthorizationUrl(req.query, req.session.idp_proofs, scope);
res.redirect(authorizationUrl);
});
router.get('/auth/callback', (req, res, next) => {
const { idp_response_code } = await idPartner.unpackProxyResponse(req.query);
const claims = await idPartner.claims(idp_response_code, req.session.idp_proofs);
return res.send(claims);
}
});
A helper method to generate a
state, nonce and codeVerifier which is used for validating the Identity response and protecting against cross-site request forgery(CSRF) attacks {
state: 'b6P4_eFMVTx_CFznmaHj9geXQUVm_z-xa8QgEmHEdNE',
nonce: 'PVShAu4ZMyfPd6zV-GitTmu-yi3TFxPJhCjv8wjyweY',
codeVerifier: 'Ek8FS-7c3AqTA-rPzF9c8-acO_-Mg4J3hpiKEzKllpc'
}
Creates an authorization url with a signed JWT (using the private key in the JKWS). Since IDPartner implements the authorization code flow you should redirect to this URL.
Parameter | Type | Description |
|---|---|---|
query | string | Required. The query parameters that started the authorization flow after the end user clicks the IDPartner Button |
proofs | string | Required. Use helper method generateProofs to generate a state, nonce and codeVerifier used for security & validations purposes |
scope | array | Required. Specify the user attributes your require for your application IDPartner supports the standard OIDC scopes. For example - ["openid", "email", "address"] |

Returns the identity provider the user selected from the selector and the JWT code response from the issuer. The
identity_provider object contains information about the provider and Know Your Business credentials that you can perform additional verification before request the consented claims. The idp_response_code is the signed and encrypted JWT containing the code used to exchange for identity claimsParameter | Type | Description |
|---|---|---|
query | string | Required. The query parameters of the callback url. The query parameters contain a signed JWT by IDPartner containing the issuer url as well as the identity provider details such as name. |
Example response:
{
name: "Chase bank",
issuer_url: "http://identity.chase.com"
}
Returns the consented identity details
Parameter | Type | Description |
|---|---|---|
idp_response_code | string | Required. The JWT response code returned from unpackProxyResponse |
proofs | object | Required. The proofs that were generated during the getAuthorizationUrl phase |
