Identity & Auth, Rebuilt for the API Era

AuthPI is an Identity Provider as a Service built with the ambition of becoming the most API friendly identity solution for B2C, B2B and B2B2B products. AuthPI’s platform offers fast and secure security around authentication and authorization, with a focus on developer experience. Our API-first approach allows you to easily integrate authentication into your applications, regardless of the technology stack you are using.

Automate & Extend with Events

React instantly to identity events. Use Webhooks to trigger custom workflows in your application, sync user data across systems, or build powerful automations—effortlessly connecting identity events to your application logic.

    "timestamp": 1678901234,
    "data": {
        "id": "user_123"
    }
}
