--- title: Auth0 API Integration on Truto slug: auth0 category: SSO canonical: "https://truto.one/integrations/detail/auth0/" --- # Auth0 API Integration on Truto **Category:** SSO **Status:** Generally available ## Unified APIs ### Unified User Directory API - **Organizations** — Organizations are the top level entity in the source application. Users are associated with an organization. - **Roles** — The Role object represents a role of a User. - **Users** — The User object represents a User. ## How it works 1. **Link your customer's Auth0 account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app. 2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request. 3. **Call Truto's API to reach Auth0.** The Proxy API is a 1-to-1 mapping of the Auth0 API. 4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field. ## Use cases - **Sync Auth0 user directories into your SaaS application** — Keep your internal user records in sync with your customers' Auth0 tenants. When users are created, updated, or deactivated in Auth0, your app reflects those changes automatically — enabling accurate access control without manual imports. - **Map Auth0 roles to your application's permission model** — Pull roles assigned to users in your customers' Auth0 tenants and map them to your native permission tiers. This lets your SaaS enforce consistent RBAC without asking customers to manually configure permissions in two places. - **Structure B2B account hierarchies from Auth0 Organizations** — Auth0 Organizations represent your customers' own customers or business units. By syncing these into your app, you can automatically build multi-tenant account structures, eliminating manual workspace setup and reducing onboarding friction. - **Power compliance audits with identity directory snapshots** — Security and compliance SaaS products can ingest the full user and role directory from a customer's Auth0 tenant to detect stale accounts, over-privileged users, or policy violations — feeding continuous compliance dashboards. - **Give support agents real-time identity context from Auth0** — Helpdesk and support platforms can surface Auth0 user profile data — like last login, metadata, and role assignments — directly in the agent's workflow, enabling faster identity-related troubleshooting without switching tools. ## What you can build - **Automated user provisioning and deprovisioning** — Create or deactivate users in your app based on changes in your customer's Auth0 user directory, ensuring access stays current across systems. - **Role-based entitlement sync** — Continuously pull Auth0 roles and map them to your internal permission levels so customers never have to double-manage access policies. - **Organization-aware account onboarding** — Automatically create workspaces or accounts in your product by syncing Auth0 Organizations, giving B2B customers a zero-config onboarding experience. - **Identity-enriched user profiles** — Pre-populate user records in your app with profile data, metadata, and org membership pulled from Auth0 — reducing manual data entry during onboarding. - **Stale account and privilege audit dashboard** — Build a compliance view that flags inactive Auth0 users or over-permissioned roles by periodically syncing directory and role data through Truto. ## FAQs ### What Unified API does Auth0 map to in Truto? Auth0 maps to Truto's Unified User Directory API, which normalizes Organizations, Roles, and Users across identity providers into a consistent schema. ### How does authentication work for connecting an Auth0 tenant? Auth0's Management API uses OAuth 2.0 client credentials. Your end users provide a Machine-to-Machine application's client ID and client secret scoped to their Auth0 tenant, and Truto handles token exchange and refresh automatically. ### Are there specific Auth0 API tools available in Truto today? Auth0-specific tools are built on request. Truto can develop and ship the integration based on your use case requirements. The Unified User Directory API schema (Organizations, Roles, Users) defines the target data model. ### Does Truto handle Auth0 Management API rate limits? Yes. Truto manages pagination and respects Auth0's rate limit headers, automatically throttling and retrying requests so your application doesn't need to implement backoff logic. ### Can I access Auth0 custom metadata fields like user_metadata and app_metadata? Custom metadata from Auth0 user profiles can be mapped through the integration. Specific field mappings are configured when the Auth0 integration is built for your use case. ### Does Truto support write operations back to Auth0? Write support (e.g., creating users, assigning roles) depends on the tools built for the integration. Discuss your specific read/write requirements with Truto to scope the integration appropriately.
