Trello Webhooks API is one of 16 APIs that [trello](https://apis.io/providers/trello/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include Event, Notification, Real-Time, and Webhook. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

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.
