  title: Toloka Assignments Projects API
  description: The Toloka API lets you build scalable, fully automated human-in-the-loop data-labeling and human-data pipelines on the Toloka crowdsourcing platform. You manage projects, pools, training pools, tasks, task suites, and assignments; collect and review Toloker responses; issue bonuses; manage skills and attachments; track asynchronous operations; and subscribe to event webhooks. Most write operations that touch large batches of tasks or suites run asynchronously and return an Operation you poll to completion.
