I will like to know if one can use webhooks to get a real-time order update while the order is getting placed. For example: In a drive-through when the cashier clicks on a coffee with no sugar option that a customer has requested on the microphone, the customer is able to see their order added to the cart that is “coffee with no sugar” before order confirmation, on a secondary screen in the drive-through.
Can this functionality be developed using Square Device webhooks or Order webhooks.
If the orders are being created by the API you can definitely get
order.updated webhook events. If the order is being taken with the Square app using open tickets it unfortunately wont trigger order webhook events.
