AsyncAPI Specification

method: searched
type: Webhooks
source: https://developer.webull.com/apis/docs
docs: https://developer.webull.com/apis/docs/webull-open-api-reference
model: streaming-push
notes: >-
  Webull does not publish an AsyncAPI document, but it ships a real event/streaming
  surface (not HTTP webhooks). Two push channels are documented and their message
  contracts are published as protobuf in the SDKs (see grpc/). Captured as a Webhooks
  event surface.
