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.
