  title: Percy REST Builds Snapshots API
  description: 'Percy is a visual testing and review platform, part of BrowserStack. Snapshots are captured and uploaded during a build by the open-source Percy CLI and SDKs (@percy/cli, @percy/core, @percy/client); that upload path is SDK-internal and is not part of this public REST reference. This document models the documented, publicly referenced Percy REST API under https://percy.io/api/v1 for reading and managing Projects, Builds, and Snapshots, plus Visual Git (branchline) sync and merge.

    Two authentication schemes are used. Read operations (list/get on projects, builds, snapshots, and all Visual Git calls) authenticate with a per-project token passed as `Authorization: Token token=<PROJECT_TOKEN>`. Write and review operations (approve/reject a build, fail or delete a build, create or update a project) authenticate with BrowserStack HTTP Basic auth using your BrowserStack username and access key.

    Request and response bodies here are honestly modeled from the public API reference. Field-level schemas are illustrative; consult the BrowserStack Percy API reference for authoritative payloads.'
