Deposit H2H - Token

POST
https://token.InstantTransfer.tech/api/v1/integration/deposit-order/
INFO
This method is used to perform recurring payments after you have obtained the card token. It does not require a PCI DSS certificate.
Payment Status Verification Before Cascading
Errors and missing responses during payment creation may occur due to transient or unforeseen circumstances and do not reliably indicate the final payment status. If you receive a 499+ error, any other error, or no response at all, for example due to a broken connection or timeout, check the payment status in our system before sending the payment through the cascade.
Thanks to the tokenization of bank cards, you can simplify the payment process for end users. Here's how it works:

Storing Card Data as a Token:#

After the first successful payment, we can store your user's card data as a token and provide it to you in the checking payment status request or callbacks.
Response example:
{
    "externalId": "a64104f5-58ff-4c8f-b704-fa28f2d0cf57",
    "orderStatus": "Processing",
    "externalParams": {
        "cardToken": null,
        "cardStorageToken": "7b9fdcbe-10cb-4e06-b8d1-25c4b1cbb081",
        "cardHolder": "JOHN WEAK",
        "cardNumber": "123412******1234"
    }
}

Associating the Token with the User:#

You need to save this token and link it to the corresponding user. For subsequent payment initiations, you will need to specify this token in the current payment method/
Request example:
  "amount": 1000,
  "currency": "EUR",
  "externalTransactionId":  "MerchantPaymentId-12345",
  "successRedirectUrl": "http://merch.com/success",
  "failedRedirectUrl": "http://merch.com/failed",
  "processingRedirectUrl": "http://merch.com/processing",
  "additionalFields": [
    {
      "key": "cardStorageToken",
      "value": "7b9fdcbe-10cb-4e06-b8d1-25c4b1cbb081"
    }
  ]
}'

Simplified User Input:#

This allows the user to enter only the CVV code on the payment page; other card details will be retrieved from the token.
