  title: Datadog Ingest and Search Logs
  summary: Submit log entries to Datadog then search the platform for those logs.
  description: >-
    A foundational Datadog Logs pipeline that first sends a batch of log
    entries to the HTTP intake endpoint for indexing and storage, and then
    runs a log search query over a time range to confirm the logs are
    queryable and to retrieve the matching events. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
