Overcharging on Ecommerce API if order has discounts


We have an overcharging issue with customers when an order is charged for using the e-commerce API if a discount is added to that order.

We use the endpoints to process orders:


A sample request-response for the TokenizedCharge is as follows (sandbox, also happens on live):

Request (note that we are sending the correct value to be charged; refer bill below):



{"id":"SBGP2SEECQ5JW","object":"order","amount":578,"tax_amount":28,"currency":"USD","charge":"RC4CGNHNR46YP","first6":"411111","created":1594282068000,"ref_num":"019100500860","auth_code":"OK5734","items":[{"parent":"1D8RRXCGXYM2J","amount":550,"description":"Chestnut Rose Cassis Tart"}],"source":{"address_line1_check":"unavailable","address_zip":"12345","address_zip_check":"pass","brand":"VISA","exp_month":"12","exp_year":"2020","last4":"1111"},"status":"paid","status_transitions":{"paid":1594282073817}}

Notice that the response amount is higher that the charge request amount.

Also note that the tax amount in the response is incorrect. Even though we don't specify it, when the discount is applied, it gives a wrong value (the tax showing up in clover orders is 25 cents but here it is 28 cents)

This incorrect tax/amount does NOT happen if there is no discounts in the order.

The overcharged scenario is clearly visible in the bill as well:

Please help us figure this issue out.

I just pinged the ecomm team about this.

It looks like this is a bug on our end. I have created an issue for further investigation.

As a workaround, we believe you can specify the order total when creating the order, that way it doesn't have to be computed by ecomm. Please see - for how to calculate the order total.

We tried your workaround and it worked. Sadly we can't use that solution.

An unpaid order shows up in the clover online dashboard if the total is set (regardless of state) since it automatically goes to OPEN state.

The problem is now merchants can see an order which may not be paid for (say user closes the payment form). Now the merchant will actually go ahead and start preparing the order since paying later when customer comes to collect is also an option.

The result is an unpaid order has been prepared which the user has actually decided not to proceed with.

  • Do you have any other solution?
  • Could you please provide an ETA on the actual fix on clover e-commerce API? (this is impacting heavily on our merchants orders who use promo discounts)

I will get in touch with the ecomm team tomorrow morning and see if they have any additional workarounds.

Hi, I still got this problem when I apply a discount to a ecomm order. The discount does not apply to the total payment.

The original question is about the method of the discount calculation, not discounts not being applied. If you want some assistance you will need to describe the problem and provide the request you are making and some sample order ids for us to look at. Please do that in a new post as your question doesn't appear to be related to this thread.
