trading_agent.gateway.routes.webhook_routes

The incoming webhook: POST /hooks/wake/ wakes a desk with a message.

It lets TradingView alerts, or the user's own scripts, wake a desk. The body is the message: plain text, or JSON whose "text" or "message" field is used, and anything else as JSON text. The webhook token goes in a token query parameter, because TradingView cannot set headers, or in an X-Webhook-Token header. It is a separate token from the gateway's, so pasting it into another service never exposes the token that controls the gateway. Without a webhook token in .env, the route answers 404, as if it did not exist.

Typical usage example:

application.include_router(WebhookRoutes(desks, secrets.webhook_token).router())
