  description: |
    Bulk-ingest and bulk-update customer conversation records — phone,
    email, chat, SMS, social, and back-office — so they can be associated
    with agents, queues, and channels for reporting, QA, and analytics.

    Used by customers running on non-Zendesk/Salesforce stacks or merging
    multiple CRMs into a unified support view.
