Charge

Single-step payment: authorization + capture in one operation.
Standard flow for most retail and restaurant merchants.

🚧 Beta — Early Access
This API is in early access. Endpoints, parameters, and response structures
may change without prior notice. Do not deploy to production without
coordinating with the Kushki integration team.

The terminal activates the card reader and blocks until the customer
completes card interaction and the acquirer responds.

Save rawResponse.transaction_reference — required to reverse the transaction with /void.

What you encrypt

The body you send is the encrypted envelope. This is the plaintext object you encrypt — the field contract, not what travels on the wire:

{
    "amount": {
        "iva": 0,
        "subtotal_iva": 0,
        "subtotal_iva0": 12000,
        "tip": 0,
        "extra_taxes": {
            "airport_tax": 0,
            "iac": 0,
            "ice": 0,
            "travel_agency": 0
        }
    },
    "client_transaction_id": "c5a3f3be-9d6f-4d39-8af5-58dbb589af79",
    "metadata": {
        "reference": "ORD-20240317-001",
        "customer_email": "user@example.com",
        "device": "SUNMI-P3"
    },
    "cashback_amount": 0
}

amount.tip is optional on charge and on authorization — the tip can be set at pre-authorization time. cashback_amount is optional on charge. On pos_tip the tip is not an optional field: it is the amount of the operation. Each one needs the matching capability enabled for your terminal; when it is not, the terminal ignores the field instead of rejecting the request.

See Authentication and request encryption for the derivation chain and the seven steps.
