Test scenarios

General information​

We recommend running the test cases before processing real payments. This section provides detailed scenarios that allow you to:

  • verify the correctness and stability of your integration
  • simulate various payment situations to ensure the system is ready to handle real transactions and to prevent potential operational issues

For a quick start, use our Postman-collection. Fork it into your private workspace, add your credentials, and run sample requests in minutes.

Requirements:​

  1. You have a merchant portal account and an existing test project with API keys.
  2. The test project configured by Tranzzo technical support.
  3. Integration completed.

Direct integration​

Prerequisites for starting the test:

  1. You have a direct integration configured.
  2. A test project with API keys is created and active.
  3. Webhook handling and status‑code processing are set up.
Test caseAction
One-step payments (purchase)One‑stage payment - a payment flow where the full amount is captured from the payer in a single transaction at the time of purchase.
Features:
  1. Charging can be performed using card data (cc_number, exp_month, exp_year, card_cvv), a Tranzzo token (cc_token), or A/GPay.
  2. 3DS verification control.
  3. Refunds available after purchase.
  4. Ability to obtain a receipt.
  5. Payment fiscalization.
info

If PCI DSS certification is in place, card data may be submitted in requests.
If PCI DSS certification is not in place, payments must use Tranzzo tokens obtained via the Tokenization widget.

  • Payment by Visa and Mastercard
  1. Create a payment request including cc_number, exp_month, exp_year, card_cvv.
  2. Use test card numbers according to the card brand.
    For example:
    Visa: 4242 4242 4242 4242
    Mastercard: 5454 5454 5454 5454
    The payment may immediately receive a final status of Success, or it may require 3DS/OTP verification. If the response contains "status_description": "3DS verification is required", open the URL in user_action_url and complete the ACS verification by clicking CONFIRM.
  3. Receive the webhook on your server — it will contain the payment status.
  • Payment via A/GPay wallets
  1. Create a payment request using cc_token.
    info

    cc_token can be obtained via the tokenization widget or from a previous hosted payment response or callback.


    In this case 3DS verification will not occur - the operation will immediately receive a final status.
  2. Receive the webhook on your server — it will contain the payment status.
  • Payment with 3DS/non‑3DS
  1. Create a payment request with card data and include the order_3ds_bypass parameter.
    Use:
    • For 3DS: order_3ds_bypass=always - test card 4242 4242 4242 4242
    • Without 3DS: order_3ds_bypass=never - test card 5555 5555 5555 4444
  2. Receive the webhook on your server — it will contain the payment status.
  • Payment with products (for fiscalisation)
  1. Create a payment request including product data.
    products - an array of items to be fiscalized. There can be multiple products, but the total sum price*qty must equal the payment amount (amount).
  2. Receive the webhook on your server — it will contain the payment status.
RefundRefund - returning funds from the merchant (or payment service) to the payer after a payment has been processed.
A refund can be issued only for a payment with status “success”.
It can be a full refund or a partial refund. Multiple partial refunds are allowed up to the original transaction amount.
  • Successful full refund
After a successful payment (Purchase):
  1. Perform a full refund for the entire amount - 10 XTS.
    Use the order_id of the transaction being refunded (this is the order_id of the successful Purchase).
  2. Receive the refund webhook on your server — it will contain the refund status.
  • Successful partial refund
After a successful payment (Purchase):
  1. Perform a partial refund for an amount less than 10 XTS (e.g., 5 XTS or 8 XTS).
    Use the order_id of the transaction being refunded (this is the order_id of the successful Purchase).
  2. Receive the refund webhook on your server — it will contain the refund status.
  • Successful full refund for a fiscalised payment.
After a successful payment (Purchase):
  1. Perform a full refund for the entire amount - 10 XTS.
    The refund request must also include details about the product being refunded.
  2. Receive the refund webhook on your server — it will contain the refund status.
Get receiptA receipt is a document for your customer that confirms a successful payment/transaction. It can be in two formats: PDF or raw HTML.
To obtain a receipt, use the following request.
