Markdown copyWebhook events
Every webhook event LIVE sends: when it is sent, which feature it serves, and its JSON Schema.
Level alerts, alert lines and order alerts arrive as signed POSTs to one address per account. Set it on Account, Level alerts, Webhook. How they are signed, retried and tested: Webhooks.

Measurements of dealer positioning, never a forecast or a trade call. This page is built from FirmTape's public contract, the same files the OpenAPI document is built from; the tests hold them against the route code. Markdown: /docs/developers/live/events.md.
