Bulk requests track the asynchronous bulk operations submitted to Harvest V3. Each time a partner hits a /v3/<resource>/bulk endpoint, Greenhouse creates a bulk request, returns its bulk_action_uuid, and dispatches each row in the data array to the matching single-resource endpoint in its own Sidekiq job. Use this endpoint to enumerate in-flight or recently completed bulk jobs for the calling client; use the single-bulk-request endpoint to retrieve per-row success and failure result files.
