  title: Hookbase Realtime API

      tags:

      summary: Stream events
      operationId: realtime_stream_events
      parameters:

        in: query
        required: false
        schema:
          type: string
        example: src_abc123
        description: Filter by source ID or slug. A slug that matches no source returns 404.

          description: Successful response
          content:
            text/event-stream: {}
      description: Server-Sent Events (SSE) stream of live inbound events and deliveries for the organization (event_received, delivery_started/completed/failed/throttled, source_rate_limited). EventSource can't set headers, so the API key may be passed as ?token= instead of Authorization. The connection is held open for ~25 seconds and then closes with a `reconnect` event; reconnect with the `Last-Event-ID` header (or the resume timestamp from that event) to continue without gaps. For a one-shot fetch instead of a live connection, use GET /api/realtime/recent.

          description: Successful response
      description: Snapshot of recent events and their deliveries, for initial load before opening the /stream SSE connection (or for polling clients that don't need push).
