Is a one-time listing import on the portal free?
Yes. Importing your listings once, from a file or from a link, is free on every plan, up to 5,000 listings per import.
Yes. Under API/XML Sync in your portal dashboard, choose the one-time import: upload a CSV, Excel (.xlsx), XML or JSON file, or paste the link to your feed and import it once. Up to 5,000 listings per import, with a preview before anything is imported.
A one-time import is not updated afterwards: a change in your file or feed reaches the portal only if you import again. To have your listings kept up to date every day, XML API Sync costs 29 USD per month.
A bigger file can be split into parts of up to 5,000 listings and imported one by one.
