Apply Customer Discount on Sale creation

aaron

So I still can't quite figure out how to apply a discount when creating a sale through the API.

The user associated with the sale has a Discount. How do I make sure that his discount is applied when creating the sale?

Hey @aaron, thank you for your question!

You'll need to make two calls. To do this efficiently I would suggest a GET and then a POST.

You'll need to first do a GET to query the customer. You can do this with the following request url:

https://api.lightspeedapp.com/API/Account/{{AccountId}}/Customer/{{CustomerId}}.json?load_relation=["Discount"]

You'll then need to get the discountID object value from the response and then put that in your POST request body

So your request url would be

https://api.lightspeedapp.com/API/Account/{{AccountId}}/Sale

{
    "employeeID": 1,
    "registerID": 1,
    "shopID": 1,
    "customerID": 16,
    "completed": true,
    "SaleLines": {
        "SaleLine": 
        {
            "itemID": 1,
            "unitQuantity": 1,
            "discountID": 10
        }
       
    },
    "SalePayments": {
    	"SalePayment": {
    		"amount": 100,
    		"paymentTypeID": 1
    	}
    }
}

Let's say the SalePayment.amount was greater than the value on the sale then the response body will return a Sale.change object which will tell you how much they've overpaid by.

I hope this helps!
