Trello Webhook Setup Guide

On connection, StackOne creates one Trello webhook named StackOne Events on the member who owns the API token. Trello sends that webhook the actions on the member’s boards. Do not delete the webhook while the connection is active.

• Trello checks the StackOne callback URL with a HEAD request before it creates the webhook. StackOne answers it automatically.
• The webhook belongs to the API token. Revoking the token in Trello deletes the webhook and stops deliveries.

Enable the Trello events you want in StackOne. Trello sends every action on the member to the webhook, and StackOne dispatches only the events you have enabled.

Trello sends one HTTP POST per action, with a JSON body that holds action (id, type, date, the member who acted, and data with the affected card, list, board, or Workspace), model (the watched member), and webhook. For changes, action.data.old holds the previous values. One change in the Trello UI can send more than one action, such as a card move that also changes its position. Enterprise-only and deprecated action types are acknowledged without being dispatched.
