This document assumes that you have access to the decrypted data from the Apple Pay payload.

Step 1: Obtain Decrypted Data

Ensure that you have decrypted data from the Apple Pay payload, which should include the necessary card information.

Step 2: Format the Decrypted Data

The decrypted data must be structured in a JSON format, containing the following key information:

applicationPrimaryAccountNumber: The primary account number of the card.

applicationExpirationDate: The expiration date of the card.

cardholderName: The name of the cardholder.

paymentData: A nested object that includes the onlinePaymentCryptogram and eciIndicator.

currencyCode: The currency code associated with the transaction.

transactionAmount: The amount of the transaction in the specified currency.

deviceManufacturerIdentifier: A unique identifier for the device manufacturer involved in the transaction.

paymentDataType: The type of payment data, such as "3DSecure" for 3D Secure transactions.

Example JSON Structure

Below is an example of how the decrypted data should be formatted:

{
	"applicationPrimaryAccountNumber": "46751XXXXXX0031147",
	"applicationExpirationDate": "300930",
	"currencyCode": "414",
	"transactionAmount": 100,
	"deviceManufacturerIdentifier": "040010030273",
	"paymentDataType": "3DSecure",
	"paymentData": {
		"onlinePaymentCryptogram": "/wAAAAAAIDcU544AAAAAgMBgAoA=",
		"eciIndicator": "5"
	}
}

Step 3: Encrypt Decrypted Data

Encrypt the formatted JSON data (from step 2) with the RSA algorithm, using the provided Tap public key.

Refer this doc for steps to encrypt RSA Encryption

Step 4: Make API Request to Authorize/Charge

Use the following cURL request to send the encrypted data to the Tap API:

curl --location 'https://api.tap.company/v2/charges' \
--header 'Authorization: Bearer sk_test_eUf******AuFDiLIqlwg9' \
--header 'accept: application/json' \
--header 'content-type: application/json' \
--data '{
