Purpose

Download URL
Use the URL present in the download_url parameter in the response of Get Bulk Write Job Details.

The CSV file will contain the first three mapped columns from the uploaded file, and three more columns — ID, Status, and Errors.
- STATUSThis column indicates if the record is added, skipped, updated, or unprocessed. 
- RECORD_IDThis column indicates the added or updated record's ID in Zoho Vertical Solutions. 
- ERRORSThis column contains the error code. The format is: - <errorCode>-<column_header> for a single error. Example: MANDATORY_NOT_FOUND-Company 
- <errorCode>-<column_header>:<errorCode>-<column_header> for multiple errors. Example: MANDATORY_NOT_FOUND-Company,Last_Name:DUPLICATE_DATA-Email 
 
The possible errors are MANDATORY_NOT_FOUND, INVALID_DATA, DUPLICATE_DATA, NOT_APPROVED, BLOCKED_RECORD, CANNOT_PROCESS, LIMIT_EXCEEDED, and RESOURCE_NOT_FOUND.
