Single Sign-On API
Introduction to OAuth, OIDC, JWT, SAML, OAuth M2M, and cross-device SSO APIs for federation and multi-application identity flows.
Overview
The Single Sign-On API is the group for federation, delegated authorization, token exchange, protocol-level SSO, and multi-application identity flows. Use this group when you are integrating standards-based SSO models such as OAuth, OpenID Connect, JWT, and SAML, or when you need service-to-service and cross-device sign-on behavior.
This group is protocol-oriented and is best approached based on the authentication model you are implementing.
What this API group covers
The current Single Sign-On API group includes:
OAuthOIDCOAuth M2MJWTSAMLCross Device SSO
These sections cover both provider-style and consumer-style SSO interactions across web, mobile, device, and service-to-service contexts.
Available sections
OAuth
Endpoints for OAuth-based authorization, token issuance, revocation, introspection, and delegated access workflows.
OIDC
Endpoints for OpenID Connect discovery, device code, token exchange, userinfo, and OIDC-compatible identity flows.
OAuth M2M
Machine-to-machine token and authorization flows for service-to-service integrations.
JWT
JWT-based SSO flows where token generation, consumption, or token-backed identity exchange is the primary integration model.
SAML
SAML-oriented operations for federated identity scenarios where LoginRadius participates in SAML-based interoperability.
Cross Device SSO
Flows used when authentication state or identity exchange must move across devices or applications.
Common workflows
This group is commonly used for:
- configuring standards-based delegated authorization flows
- exchanging device or authorization codes for tokens
- introspecting or revoking tokens
- implementing JWT-backed SSO between applications
- integrating SAML-based federation
- supporting M2M access for backend services
- handling cross-device authentication continuation
When to start here
Start with the Single Sign-On API when:
- you are implementing protocol-driven federation
- your integration is centered on OAuth, OIDC, JWT, or SAML
- you need service-to-service authorization
- you need token exchange or delegated auth flows
- you are building cross-app or cross-device identity continuity
If you are building basic customer registration and login, start with the Authentication API first.
Next steps
- Review the Authorization page for protocol-specific auth expectations in this group
- Start with OAuth or OIDC for standards-based delegated authorization
- Use JWT or SAML when the downstream integration requires those specific federation models
- Use OAuth M2M for backend service authentication
