Bulk Post guide

Everything you need in one place: how scheduling works, how to prepare your CSV, which due_date formats are supported, and how to handle media URLs.

CSV rules
  • Use the official template with the first row as headers.
  • Do not rename or reorder headers.
  • You can delete columns you do not need, but keep the header row intact.
Scheduling
  • Use due_date to control when each row should publish.
  • Posts publish on the specified date and time.
  • ISO-like formats are the safest option for consistent scheduling.
