  title: Honeycomb Events API
  description: >-
    The Honeycomb Events API is the lowest-level interface for sending event
    data to Honeycomb. It supports both single event creation and batch event
    submission, allowing developers to send structured telemetry data directly
    to Honeycomb datasets. While Honeycomb recommends using OpenTelemetry or
    Beeline SDKs for most instrumentation use cases, the Events API provides
    direct control for custom integrations and specialized data pipelines. Also
    includes Kinesis Events for processing streaming events from Amazon Kinesis.

      summary: Create an event
      description: >-
        Sends a single event to the specified dataset. Using this endpoint for
        anything more than testing is highly discouraged. Sending events in
        batches via the batch endpoint is much more efficient and should be
        preferred.

        recommended way to send events to Honeycomb. The request body is
        limited to 1MB of raw (potentially compressed) data. Dataset names
        are case insensitive.
