Shipatron will automatically synchronise new products and product changes when you've successfully added a channel. For some types of channels, this happens instantly, for others it may take up to 2 hours for product listings to be found.
Remember: The first marketplace you connect to Shipatron is your master. So make sure you connect your core store (usually Shopify, Big Cartel or Squarespace) first.
You can see which products have been synchronised with Shipatron by clicking “products” within the Shipatron app. The column titled “source” shows which of your marketplace the product was found in.
If you’ve added a product but it’s not showing up in Shipatron then you can:
For Squarespace sites, Shipatron will not be able to access your product list unless your products are published at the relevant location. This can be configured in Settings > Squarespace > Settings.
So if you've configured "shop" as the collection you wish Shipatron to collect, then shipatron will attempt to retrieve your file list from yourstorename.com/shop?format=json.
If you’ve completed the steps above, and products are still not appearing, please contact support.
