Take Payments

December 09, 2024

Accept payments with a certified POS terminal from your point of sale through the Raw card-present API. With the Raw card-present API you can use and manage your own terminals, connecting to our payment network to process transactions. You must securely generate and manage the cryptographic keys that will allow you to encrypt the information read from the card through the terminals. Send the required information in the request to perform a successful operation through our API.

Operations

Discover all the operations available through Raw card-present API integrations.

Sale

Take present payment with physical or digital cards at your local store via a terminal. The terminal allows you to read your customer’s card and perform operations involved in the DUKPT process. The responsibility of your POS system is to send the data read from the terminal to Kushki for processing.

To make a sale, consume the Single payment endpoint, set the transaction mode (transaction_mode) to Authorization, the transaction type (transaction_type) to charge, and send the rest of the required information.

Pre-authorization

In case you need to reserve an amount from your client’s bank account, you can use the pre-authorization service. For example, when your merchant needs to request a deposit to guarantee that the total cost will be financed at the end of the service, you can retain a specific amount from your client’s bank account.

To perform a pre-authorization, consume the Authorization and capture endpoint, set the transaction mode (transaction_mode) to Authorization, the transaction type (transaction_type) to preAuth, and send the rest of the required information.

Request example:

{
  "card": {
    "card_holder_name": "John Doe"
  },
  "amount": {

}

Reauthorization

If you need to modify the amount of a previously pre-authorization or extend the date of the capture, you can use the reauthorization service. Send an amount equal to $0 in a reauthorization to extend the capture period or send an amount in the reauthorization to extend the pre-authorization.

To perform a reauthorization, consume the Authorization and capture endpoint, set the transaction mode (transaction_mode) to Authorization, the transaction type (transaction_type) to reAuthorization, and send the rest of the required information.

Capture

Once you are required to collect the funds from your customer’s bank account, capture the amount for only the products or services used.

The requested capture corresponds to the sum of the authorization and all reauthorizations made that have not been canceled.

By receiving payments under the authorization and capture scheme, your business can ensure the availability of the amount on your customer’s card for a maximum of 28 days for credit cards and 7 days for debit cards. If the transaction payment is not captured during the mentioned times, the held funds will be released by the issuing bank back to the cardholder.

To capture a payment, you need to consume the Authorization and capture endpoint, set the transaction mode (transaction_mode) to Authorization, the transaction type (transaction_type) to capture and add the transaction_reference property with the value of the reference returned at the time of performing a pre-authorization
