> Test cards and minimum validation scenarios.

<Warning>
  The numbers on this page are fictitious test data for controlled environments only. They do not represent real accounts or BINs and must never be used for real payments.

## Published test data

| Result     | Card                  | Expiration | CVV   | Intended use                   |
| ---------- | --------------------- | ---------- | ----- | ------------------------------ |
| Authorized | `4859 5100 0000 0051` | `12/26`    | `365` | Integration                    |
| Declined   | `4111 1111 1111 1111` | `12/26`    | `648` | Coordinated production testing |
| Declined   | `5038 4900 0000 0032` | `12/26`    | `517` | Coordinated production testing |

The cards are not enrolled in Verified by Visa. Always confirm current test data with the acquirer, especially before production testing.

## Minimum integration scenarios

### Cancellation and return

Start a transaction, select **Return to merchant**, and verify that WooCommerce receives an operation number and records a rejected or cancelled result.

### Low-amount authorization

Submit approximately USD 1.00 or the local-currency equivalent with the card ending in `0051`. Expect an operation number and an authorized result.

### High-amount authorization

Submit approximately USD 1,000.00 or the local-currency equivalent with the card ending in `0051`. Expect an operation number and an authorized result.

## Controlled production scenarios

Validate these response fields:

* `purchaseOperationNumber`
* `purchaseAmount`
* `authorizationResult`
* `errorCode`
* `errorMessage`

| Scenario                              | Expected result                                                                                     |
| ------------------------------------- | --------------------------------------------------------------------------------------------------- |
| User selects **Return to merchant**   | `authorizationResult: 05`, `errorCode: 2300`, `errorMessage: User Cancelled in PASS 1`              |
| Visa test card ending in `1111`       | `authorizationResult: 01`, `errorCode: 05`, `errorMessage: Do not honor`                            |
| Mastercard test card ending in `0032` | `authorizationResult: 01`, `errorCode: 14`, `errorMessage: Invalid account number (no such number)` |

<Note>
  Run production tests only with the acquirer's authorization and coordination. Preserve evidence and send it to the assigned integration contacts.
</Note>

## Recommended evidence

Record the date and time, environment, order and operation numbers, amount and currency, result codes, and technical logs or screenshots. Never expose keys or sensitive information.
