Shopify POS Webhook

[frontflip]

Does the REST API webhooks detect Shopify POS orders?

Thanks

Hi @frontflip , 

Yes - webhooks should be fired when POS orders are placed.

Does this also apply for when items are added to the POS cart?

I am currently trying to build an app that adds a deposit fee automatically to products added to the cart.

I  was looking into the POS Cart App Extensions here (https://shopify.dev/docs/pos/pos-cart-app-extension) but it seems these are only for adding discounts and also require a button push. I am looking for the line item to be added to the cart automatically based on my apps logic for the each item that gets added to the cart by the cashier in the POS.

Is this even possible?

@BraydenGirard unfortunately I don't think what you want to do is possible as there is no "listener" for POS cart actions that developers have access to, outside of the POS cart app extension. The only way I could think to do it would be to build an embedded app that lets (read: forces) the merchant to add products to the cart there instead of natively and then use App Bridge Cart Actions to add your deposit fee products programmatically.
