Usage

All operations return typed response objects with convenience methods.

Single Buy

use Bancard\Util\Currency;

$response = $bancard->singleBuy([
    'shop_process_id' => '7777777',
    'amount' => '10000.00',
    'currency' => Currency::PYG->value,
    'return_url' => 'https://app.test/return',
    'cancel_url' => 'https://app.test/cancel',
]);

if ($response->isSuccessful()) {
    $processId = $response->getProcessId();
}

Single Buy (Zimple)

$response = $bancard->singleBuyZimple([
    'shop_process_id' => '7777777',
    'amount' => '10000.00',
    'currency' => Currency::PYG->value,
    'return_url' => 'https://app.test/return',
    'cancel_url' => 'https://app.test/cancel',
]);

Single Buy Confirm

Generates the confirm token for the iframe callback (no HTTP request is made).

$response = $bancard->singleBuyConfirm([
    'shop_process_id' => '7777777',
    'amount' => '10000.00',
    'currency' => Currency::PYG->value,
]);

$token = $response->getToken();

Single Buy Get Confirmation

$response = $bancard->singleBuyGetConfirmation([
    'shop_process_id' => '7777777',
]);

if ($response->isApproved()) {
    $code = $response->getResponseCode();
}

Single Buy Rollback

$response = $bancard->singleBuyRollback([
    'shop_process_id' => '7777777',
]);

Register a New Card

$response = $bancard->cardsNew([
    'card_id' => '123',
    'user_id' => '456',
    'return_url' => 'https://app.test/return',
]);

$processId = $response->getProcessId();

List User Cards

$response = $bancard->usersCards([
    'user_id' => '456',
]);

foreach ($response->getCards() as $card) {
    echo $card->card_masked_number;
}

Charge (Token-Based Payment)

$response = $bancard->charge([
    'shop_process_id' => '7777777',
    'amount' => '10000.00',
    'currency' => Currency::PYG->value,
    'alias_token' => 'card_alias_token',
]);

if ($response->isApproved()) {
    // Payment successful
}

if ($response->is3dsRedirect()) {
    // 3DS authentication required
}

Delete Card

$response = $bancard->deleteCard([
    'user_id' => '456',
    'alias_token' => 'card_alias_token',
]);

Preauthorization Confirm

$response = $bancard->preauthorizationConfirm([
    'shop_process_id' => '7777777',
]);

if ($response->isApproved()) {
    // Preauthorization confirmed
}

Billing Client Info

$response = $bancard->billingClientInfo([
    // billing client info fields
]);

$client = $response->getClient();

Billing Cancel

$response = $bancard->billingCancel([
    'shop_process_id' => '7777777',
]);

Response Objects

All responses extend Bancard\Response\Response and provide:

• isSuccessful(): bool -- checks if status === 'success'
• getStatus(): ?string
• getMessage(): ?string -- first message description
• getErrorKey(): ?string -- error key from messages
• raw(): \stdClass -- access the raw response data

Specialized responses add operation-specific methods (e.g., getProcessId(), isApproved(), getCards()).

Error Handling

use Bancard\Exception\ValidationException;

try {
    $response = $bancard->singleBuy($payload);
} catch (ValidationException $e) {
    // Missing required fields
    $errors = $e->getErrors(); // ['shop_process_id', 'amount', 'currency']
}

Amount Formatting

use Bancard\Util\Amount;

$formatted = Amount::format(10000); // "10000.00"

Upgrading from v1
