Integrate Shopify with Switch. This app allows Shopify to send orders to Switch via webhooks without requiring the Switch server to be accessible from the public internet.
Whenever a customer pays for an order Shopify will automatically send the complete order metadata in JSON format to a cloud 'reflector' service run by Apago which securely captures and stores it. You just need to add this App to a flow and it will connect to the reflector server and download the queued orders for the store you have configured in the App's properties.
There is no additional cost to use the reflector service. It's bundled with the App subscription.
