What happens if my XML API Sync subscription ends?
The daily sync pauses. Your listings stay exactly as they are and nothing is deleted.
If your subscription ends, the daily sync pauses. Your listings stay exactly as they are and nothing is deleted. Renew at any time and the sync starts again with the mapping you saved.
You can also pause the sync yourself and resume it later, or remove the feed. Removing a feed stops the sync; the listings it brought in stay on your account.
