  description: >-
    Pria API Documentation Praxis's developer platform is a core part of our
    mission to empower organizations to grow better. Our APIs are designed to
    enable teams of any shape or size to build robust integrations that help
    them customize and get the most value out of Pria. All Pria APIs are built
    using REST conventions and designed to have a predictable URL structure.
    <br/>  <br/>They use many standard HTTP features, including methods (POST,
    GET, PUT, DELETE) and error response codes.  <br/> <br/>All API calls are
    made under https://hiimpria.ai/api and all responses return standard JSON.
    In these docs, you'll find lists of all available endpoints for a given API,
    along with interactive code blocks for building requests. For walkthroughs
    of basic usage for these APIs, check out the API guides. <br/> <br/>A
    session that a course page (Canvas) opened for an administrator — or that a
    Digital Twin's sign-in provider opened for one of its people — starts with
    user rights in that twin only: until the person confirms it's them with a
    code (POST /api/user/launch-scope/challenge, then /api/auth/mfa-resend and
    /api/auth/mfa-verify), every route outside that twin's day-to-day work
    answers 403 with code LAUNCH_SCOPE_STEP_UP and the twin's id.
