Add discount orderlines using /dwapi/ecommerce/carts/{secret}/items

Hi guys,

I need to create some orderline programmatically to handle some complicated discount scenarios.

I was wondering if I can use the /dwapi/ecommerce/carts/{secret}/items endpoint to do so. I have managed to create an orderline (using an existing productID) but I could not manage to provide price information.

Is this even possible? And one more thing. Can I also set the OrderLineType from the API? I see that OrderLineViewModel does not have a property for it.

Thank you,

Adrian

Hi,

the property is availble and can be used in the endpoint in fact. Please, find the attachment.

Thank you Oleg,

I will try it out.
What about setting the price for the orderline?

Thank you,
Adrian

Hi Oleg,

I will try to be more specific about what I am trying to do.

I am using this POST endpoint:

/dwapi/ecommerce/carts/{secret}/items

and I am trying to send this Payload:

{
"ProductId": "SOMEID",
"ProductVariantId": "",
"ProductLanguageId": "LANG17",
"ProductName": "Discount TEST",
"Quantity": 1,
"UnitPrice": "0.25",
"OrderLineType": "ProductDiscount",
"UnitPrice": {
"Price": 1.4,
"VATPercent": 20,
"CurrencyCode": "EUR"
}
}

No matter what I do, I cannot add a discount orderline.

I have tried various approaches for the Price and also for the OrderLineType but without any luck.

I have noticed that an empty ProductID will not generate an orderline, with a fake ProductID I can create the orderline but wthout OrderLineType and Price.

Can you please suggest how I can accomplish this action?

Thank you,

Adrian

Hi Adrian,

I see the same results with code above except if use 'Fixed' orderlinetype (orderlinetype=2 in db) and 'OrderDiscount' (0). Prices are zero in the both cases. I've asked our expert to comment the issue here, so let't wait for the feedback.

Hi Adrian,

It is not possible to set a price using web api.

Best regards,

Vladimir

Hi Oleg, Vladimir,

Thank you both for the details.

@Vladimir is this just a limitation of the POST method or is it valid also for PATCH method? Is this going to be supported in the future?

Thank you,

Adrian

Yes, this limit is valid for PATCH method too.
Note that all your discount manipulations should be supported by existing discount types: https://doc.dynamicweb.com/documentation-9/ecommerce/discounts/discounts-offers

There is a posibility to create a discount extention, see 'DiscountExtenderBase' example: https://doc.dynamicweb.com/training/t3-platform-developer/t3-platform-developer/3-3-extending-ecommerce

Is this could be a solution?

Best regards,
Vladimir

Hi Vladimir,

I was trying to avoid using the discount logic since our scenario is a bit complicated and I was trying to manipulate the cart from the interface instead.

But I guess I will have to fall back to the discount logic.

Thank you very much for all your replies.
