# Get QR Code This endpoint is used to obtain a transaction based QR code. - Host Direct - Locally Installed UTG See the Integration Methods and URLs Section sections of the Development Quick Start guide for details regarding each processing option. Endpoint: POST /qrpayments/getqrcode Version: 1.7.43 Security: AccessToken ## Header parameters: - `InterfaceVersion` (string, required) Refers to the version of the program or application that is sending requests to Shift4. The following special characters are not allowed: $ % : ^ - ~ , ? “ ” ‘ ’ { } [ ] \ + = Example: "2.1" - `InterfaceName` (string, required) Refers to the name of the program or application that is sending requests to Shift4.

If other amount fields are sent, they must be included in the total amount. Amount cannot be zero. - `amount.tax` (number, required) The amount of sales tax charged for a transaction. The tax amount is used by businesses to track tax expenses for accounting purposes. Identifying the tax amount also helps consumers understand the total amount that they were billed. This field is part of Level 2 card data. - `amount.tip` (number) The tip amount of the transaction. - `amount.cashback` (number) Specifies the cashback amount in a transaction. When using a UTG-controlled PIN pad with the ALLOWCASHBACK API Option, this field will return the cashback amount requested by the consumer.

This will bypass prompting the consumer for a cashback amount. - `transaction` (object, required) - `transaction.invoice` (string, required) 10-digit invoice number assigned by the interface to identify a transaction. An invoice number serves as a unique key that identifies a transaction within a batch in Shift4's Gateway. - `transaction.saleFlag` (string, required) Specifies a transaction is a sale (‘S’) or authorization (‘A’). Value sent in the [Get QR Code](/apis/payments-platform-rest/openapi/qr-payments/getqrcode) request will be returned in the [Get QR Details](/apis/payments-platform-rest/openapi/qr-payments/getqrdetails) response. Enum: "A", "S" - `transaction.vendorReference` (string) Optional field for information that can be searched in the merchant portal. ## Response 200 fields (application/json): - `result` (array) - `result.dateTime` (string) The date and time in ISO 8601 format including the timezone offset (yyyy-mm-ddThh:mm:ss.nnn+hh:mm).

Value sent in the [Get QR Code](/apis/payments-platform-rest/openapi/qr-payments/getqrcode) request will be returned in the [Get QR Details](/apis/payments-platform-rest/openapi/qr-payments/getqrdetails) response. Enum: "A", "S" - `result.transaction.vendorReference` (string) Optional field for information that can be searched in the merchant portal. - `result.transaction.responseCode` (string) Code indicating the Shift4 host response. Value | Description | Details -------|---------------------------------------------------------------------------------------|-------- A | Approved | The transaction is approved. C | Approved | The transaction is approved without requiring additional authorization because it is less than or equal to a ceiling amount. (The ceiling amount is the original authorization amount multiplied by the tolerance per the merchant’s settings with Shift4.) D | Declined | The transaction is declined. Note: Shift4 automatically declines AVS/CSC failures if the [POSHANDLEAVSFAIL Api Option](/guides/appendices/api-options#poshandleavsfail) was not sent in the request. e | [Error](/guides/appendices/error-codes) | There is an error condition. f | [AVS or CSC failure](/guides/response-handling/understanding-avs-and-csc-verification)| An AVS or CSC failure has occurred (credit card only). Note: This value will only be returned if the [POSHANDLEAVSFAIL Api Option](/guides/appendices/api-options#poshandleavsfail) was sent in the request. P | [Partial approval](/guides/advanced-concepts/partial-approval) | A partial approval has occurred. Check for the approved amount. R | Voice referral | The transaction requires a voice referral. [blank]| Status is unknown | The approval status is unknown. X | Expired card | There is an error condition due to the card being expired. S | SCA Online PIN required | The contactless EMV transaction requires strong customer authentication to continue. The terminal must gather the online PIN if supported by the device form factor and CVM list then resubmit the transaction request. I | SCA Interface switch required | The contactless EMV transaction requires strong customer authentication to continue. The terminal must look at the form factor indicator to determine if the transaction should be declined, switched to EMV contact or tapped again using CDCVM.
