Working with transaction data (Payment Connector)

Retrieving transaction information

The payment responses returned by the Clover device provide detailed transaction data for your application to use and display.

Understanding surcharges (US only)

Some merchants are configured to add a surcharge to all credit card transactions they process. This surcharge is a set percentage of the post-tax order total. If you are going to display transaction data in your app, you will need to use data from a few different fields.

{
  "success": true,
  "result": "SUCCESS",
  "payment": {
    "id": "WSPDBEE2RKSEA",
    "result": "SUCCESS",
    "order": {
      "id": "88KCNJ7CS3JN4"
    },
    "amount": 2428,
    "createdTime": 1599672721991,
    "additionalCharges": {
      "elements": [
        {
          "amount": 84,
          "type": "CREDIT_SURCHARGE",
          "id": "AGPT72N3N5TDM",
          "rate": 35000,
          "payment": {"id": "WSPDBEE2RKSEA"}
        }
      ]
    }
  },
  "isSale": true
}

The transaction response includes an additionalCharges object showing the following:

• amount - the number of cents paid as a surcharge on the credit card transaction
• rate - the percentage of the total used to calculate the amount multiplied by 10000. A 3.5% rate is represented as 35000.
• type - the kind of additional charge processed for the transaction. At the time of this writing, this can be one of three values:
  • CREDIT_SURCHARGE - a percentage fee added to a credit card transaction to cover the cost of processing
  • CONVENIENCE_FEE - a fixed amount added to a debit or credit transaction processed using an alternative payment channel
  • INTERAC_V2 - a fixed amount added to Interac debit transactions
• payment - contains the UUID of the associated payment

🚧

IMPORTANT

The total amount paid by the customer is the sum of the payment amount and additionalCharges.amount. In the example, the customer was charged $25.12 (the $24.28 amount plus a 3.5% surcharge of $0.84).

This expansion can also be used for refunds and voids. The surcharge data for a transaction is reported in the RefundPaymentResponse.refund.additionalCharges or VoidPaymentResponse.payment.additionalCharges object.

{
  "success": true,
  "result": "SUCCESS",
  "reason": "voidSent",
  "message": "No extended information provided.",
  "payment": {
    "id": "SPLHGTD25ALN4",
    "order": {
      "id": "N70SW8KUW28VY"
    },
    "amount": 2130,
    "tipAmount": 0,
    "taxAmount": 0,
    "result": "SUCCESS",
    "additionalCharges": [
      {
        "amount": 74,
        "type": "CREDIT_SURCHARGE",
        "id": "KHGT70N3N5SSD",
        "rate": 35000,
        "payment": {"id": "SPLHGTD25ALN4"}
        
      }
    ]
  }
}

The response includes an additionalCharges object showing the following:

• amount - the number of surcharged cents refunded or voided
• rate - the decimal percentage of the total used to calculate the amount
• type - the kind of charge added to the original payment. At the time of this writing, this can be one of three values: CREDIT_SURCHARGE, CONVENIENCE_FEE, or INTERAC_V2
• payment - contains the UUID of the associated payment

Tips and surcharging

There are two ways a customer can add a tip to a payment: on the Clover device or on a paper receipt. If a tip is added on the device, the tipAmount is added to the payment amount and then the sum is multiplied by the surcharge rate to determine the total charged to the customer's card. For example, if the order amount is $25.00 and the customer adds a 20% tip ($5), they will be charged an additional a 3.5% surcharge ($1.05) if they pay with a credit card.

(2500 + 500) * 1.035 = 3105

If a tip is added on paper, the tip is not included when calculating the surcharge.

Partial authorizations and surcharging

If a surcharged credit card payment results in a partial authorization, the entire transaction will be declined. The customer will need to use another card or payment method to complete the transaction.
