# Publish the revision served by a READY release service (expected-head CAS)

> Promotes the service's revision to the project's published head only when the artifact is sealed, the service is ready, and the current head still equals `expectedHead`. Requires publish rights (owner or listed editor). A lost race answers 200 with `ok:false, code:HEAD_CONFLICT` and the current head.

    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.
