  title: Spring Integration HTTP Inbound Gateway API
  description: >-
    Spring Integration HTTP inbound channel adapters and gateways expose
    configurable HTTP endpoints that receive messages and route them into
    Spring Integration message flows. Inbound HTTP gateways support request/reply
    messaging while inbound channel adapters support one-way message ingestion.
