Asynchronously import the profile data of many investment entities in a single request. Each row targets one investment entity by ID (Anduin ID or tracking ID) and supplies the profile field values to write; you may import up to 1000 profiles per request.

Fields you provide are updated, fields you omit are left unchanged, and an explicit empty value clears the field. importTemplateId and overwriteArrayValues are set once per request and apply to every row.

This endpoint initiates a background job and returns a request ID immediately, preventing timeouts. Once complete, the job provides a secure URL to download a per-investment-entity report (success or failure with error detail) as a CSV file, following the selected import template.

This process is asynchronous; you can find a complete guide to the workflow in our Asynchronous Bulk Import API documentation.
