We check your account for new listings every 2 hours. You can, however, speed up this process manually after you have created the listing on your booking channel.
If you added a new listing and want to speed up this process, you can re-sync your account:
Go to Settings, then click on Connected Accounts.
Select the connected account you want to re-sync.
Click on the Edit button next to the connected account hosting this new listing.
Choose the Re-sync option.
Allow a few minutes for us to sync with the channel and import your new listing. It will be displayed in the Properties tab with a "New" label. You can also find it in the New properties sub-tab (a convenient place to find all of your new listings!).
