    description: The Trello REST API provides programmatic access to Trello boards, lists, cards, members,
      labels, checklists, and other resources that make up the Trello project management platform. Developers
      can create, read, update, and delete Trello objects, manage team collaboration workflows, and automate
      task management processes. The API uses key and token based authentication and returns JSON responses
      for all endpoints.

        type: AsyncAPI
    description: The Trello Webhooks API allows developers to receive real-time notifications when changes
      occur on Trello models such as boards, lists, and cards. Rather than polling the REST API for updates,
      webhooks push event data to a specified callback URL via HTTP POST requests containing JSON payloads.
      Webhook requests are signed with HMAC-SHA1 for verification, and webhooks are scoped to the permissions
      of the token used to create them.

      Power-Ups allow developers to add custom functionality to Trello boards, including custom fields,
      board buttons, card buttons, card badges, and card detail sections. The Power-Up framework provides
      a client library with utilities and helpers for interacting with the Trello interface, managing
      authorization, and accessing the REST API from within the Power-Up context.
