Import history for one ICP, newest first, covering both dashboard file uploads and imports made through this API (source: API). Use it to confirm an import landed and how many contacts it added.

Match the import response's uploadSummary.id. Poll every 10 seconds until status is COMPLETED or FAILED. Completion means contacts were inserted; verification counts may still be pending and email generation may still be running. Use Get Step Email Status to check generation, then Process Step Emails to fill missing AI copy after a large import.
