Integrate Through OIDC

OpenID Connect (OIDC) is an authentication protocol, based on the OAuth 2.0 specifications. While OAuth 2.0 is about resource access and sharing, OIDC is all about user authentication.

MIRACL Trust is a standards-compliant OpenID Connect provider. You can use any OIDC Relying Party Library to integrate with MIRACL Trust. For a list of certified OpenID Connect Libraries, see https://openid.net/developers/certified/.

This page provides general information about integrating with the OpenID Connect implementation exposed by MIRACL Trust. For high-level information about OIDC, see https://openid.net/connect/. For a full reference of all MIRACL Trust OIDC endpoints see the OIDC API Reference.

# Configuration Discovery

MIRACL Trust exposes OpenID Connect (OIDC) configuration discovery (https://api.mpin.io/.well-known/openid-configuration). This is used for automatic configuration of your applications.

If you already have an OIDC implementation available in your application, you can easily configure it to use the MIRACL Trust service. Most clients are configured only with the issuer URL (https://api.mpin.io) and are automaticaly configured using configuration discovery.

# Authorization Endpoint

The user authorization endpoint in MIRACL Trust is https://api.mpin.io/authorize. An example for generated authorization URI is:

https://api.mpin.io/authorize?client_id=<YOUR_CLIENT_ID>&redirect_uri=<YOUR_REDIRECT_URI>&response_type=code&scope=openid+email

Here is a short description of the params in that URI:

• client_id - The Client ID generated on application creation in the MIRACL Trust Console. (The one mentioned in the Get started section)
• response_type - Determines what authorization processing flow is used.
• scope - The OIDC scopes that are used during authentication to authorize access to a user’s details (supported scopes).
• redirect_uri - The place where your application receives and process the response from MIRACL.
• state - Used to maintain state between request and callback.

For a full list of supported parameters and their description see the OIDC API Reference.

For more information, you can visit the Authorization Endpoint section in the OIDC Specification.

# JWKS

JSON Web Key Set (JWKS) contains the public keys that should be used to verify the ID and access JSON Web Tokens (JWT) issued by MIRACL Trust. You can fetch JWKS from https://api.mpin.io/oidc/certs.

Note that you should not hardcode the JWKS, as it is a subject of change. The OIDC client needs to fetch the JWKS dynamically in order to assure that the ID and access tokens are properly signed.

# Token Endpoint

To exchange ID and access tokens use the https://api.mpin.io/oidc/token endpoint. You have to authenticate requests with Client ID and Client Secret.(Get Started). The token endpoint supports basic and post authentication.

For more details refer to OIDC API Reference

# Userinfo Endpoint

To recieve information about the authenticated user use the https://api.mpin.io/oidc/userinfo endpoint. You must authenticate the request with an access token (returned from the token endpoint).

For more details refer to OIDC API Reference

# OIDC Authentication Flow

sequenceDiagram User -> Relying Party: Start Authentication Relying Party -> MIRACL Trust: Authentication request MIRACL Trust -> User: Authenticate user User -> Relying Party: Redirect with access code Relying Party -> MIRACL Trust: Exchange code for ID and access tokens User -> Relying Party: Authorize user
