### Example model with computed total and controller usage

Source: https://github.com/creagia/laravel-redsys

Complete model example computing total from items sum, plus controller call to createRedsysRequest and redirect. Shows typical usage flow.

```php
namespace App\Models;

use Creagia\LaravelRedsys\Concerns\CanCreateRedsysRequests;
use Creagia\LaravelRedsys\Contracts\RedsysPayable;
use Illuminate\Database\Eloquent\Model;

class Order extends Model implements RedsysPayable
{
    use CanCreateRedsysRequests;

    public function getTotalAmount(): int
    {
        return (int) collect($this->items)->sum('price_cents');
    }

    public function paidWithRedsys(): void
    {
        $this->update(['status' => 'paid']);
    }
}
```

```php
return Order::find($id)->createRedsysRequest('Cart payment', PayMethod::Card)->redirect();
```

--------------------------------

### Install laravel-redsys via Composer

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

Run this command to install the package using Composer.

```bash
composer require creagia/laravel-redsys
```

--------------------------------

### CreateRedsysClient usage example

Source: https://github.com/creagia/laravel-redsys

Resolves the CreateRedsysClient action from the Laravel container and invokes it to get a RedsysClient instance.

```php
use Creagia\LaravelRedsys\Actions\CreateRedsysClient;

$client = app(CreateRedsysClient::class)(); // RedsysClient
```

--------------------------------

### Implementation example of RedsysPayable

Source: https://github.com/creagia/laravel-redsys

Shows a model implementing RedsysPayable with CanCreateRedsysRequests trait. getTotalAmount returns total_cents, paidWithRedsys updates status to 'paid'.

```php
use Creagia\LaravelRedsys\Concerns\CanCreateRedsysRequests;
use Creagia\LaravelRedsys\Contracts\RedsysPayable;

class Order extends Model implements RedsysPayable
{
    use CanCreateRedsysRequests;

    public function getTotalAmount(): int
    {
        return $this->total_cents;
    }

    public function paidWithRedsys(): void
    {
        $this->update(['status' => 'paid']);
        // email confirmation, inventory update, ...
    }
}
```

--------------------------------

### redirect() usage example

Source: https://github.com/creagia/laravel-redsys

Shows how to use redirect() from a controller: find an Order, create a Redsys request with a description and payment method, then return the redirect response.

```php
public function pay()
{
    $request = Order::find(1)->createRedsysRequest('Product description', PayMethod::Card);
    return $request->redirect(); // return this from a controller
}

```

--------------------------------

### Query and filter redsysCards relation

Source: https://github.com/creagia/laravel-redsys

Use eager loading with constraints on the redsysCards relation, or apply orderByDesc to get the most recent card. Works like any Eloquent MorphMany relation.

```php
$cards = Team::with(['redsysCards' => fn ($q) => $q->latest()])->find($id);

$lastCard = $user->redsysCards()->orderByDesc('created_at')->first();
```

--------------------------------

### Facade usage example

Source: https://github.com/creagia/laravel-redsys

Shows typical facade usage. The 'redsys-request' binding is not registered by the provider in this checkout, so this call would resolve an unbound class unless the application registers the singleton itself.

```php
\Creagia\LaravelRedsys\Facades\RedsysRequest::someMethod();
```

--------------------------------

### Usage example: find request by order number and call paidWithRedsys

Source: https://github.com/creagia/laravel-redsys

Queries a Request by order_number from a Redsys response, checks if the related model is RedsysPayable, and calls paidWithRedsys() on it.

```php
$request = Request::query()
    ->where('order_number', $redsysResponse->parameters->order)
    ->first();

if ($request && $request->model instanceof RedsysPayable) {
    $request->model->paidWithRedsys();
}
```

--------------------------------

### Initial token request with storeCardOnModel

Source: https://github.com/creagia/laravel-redsys

Create a Redsys request on a payable model, request a card token with CofType::Recurring, and store the card on the given model (e.g., a Team). Returns a redirect response.

```php
$redsysRequest = $productModel->createRedsysRequest(
    productDescription: 'Product description',
    payMethod: PayMethod::Card,
)->requestingCardToken(CofType::Recurring)->storeCardOnModel($team);

return $redsysRequest->redirect();
```

--------------------------------

### redsysCards() method signature

Source: https://github.com/creagia/laravel-redsys

Returns a MorphMany relation of RedsysCard where the morph model points to the owning model. Maps to redsys_cards.model_type and redsys_cards.model_id columns.

```php
public function redsysCards()
```

--------------------------------

### Querying notification logs with relationship

Source: https://github.com/creagia/laravel-redsys

Example of fetching the latest notification logs with the related redsysRequest, then accessing merchant_parameters and getStatus() for each log.

```php
use Creagia\LaravelRedsys\RedsysNotificationLog;

$logs = RedsysNotificationLog::with('redsysRequest')->latest()->get();

foreach ($logs as $log) {
    $params = $log->merchant_parameters; // array
    $status = $log->getStatus();
}
```

--------------------------------

### post() usage example

Source: https://github.com/creagia/laravel-redsys

Shows how to call post() and handle a transport error response. Check if the response is an instance of PostRequestError to access its message and code properties; catch exceptions for upstream errors.

```php
try {
    $response = $builder->post();
    if ($response instanceof \Creagia\Redsys\Support\PostRequestError) {
        // transport error response: $response->message, $response->code
    }
} catch (\Exception $e) {
    // handled by HandleRedsysResponse / upstream exceptions
}

```

--------------------------------

### Using getStatus() with switch

Source: https://github.com/creagia/laravel-redsys

Example of handling the RedsysRequestStatus enum returned by getStatus(). Covers Success, Error, and Pending cases, where Pending means no Ds_Response was notified.

```php
use Creagia\LaravelRedsys\RedsysNotificationLog;
use Creagia\LaravelRedsys\RedsysRequestStatus;

$status = $log->getStatus(); // RedsysRequestStatus enum
switch ($status) {
    case RedsysRequestStatus::Success:
        // handle
        break;
    case RedsysRequestStatus::Error:
        // handle
        break;
    case RedsysRequestStatus::Pending:
        // never notified a Ds_Response
        break;
}
```

--------------------------------

### usingCard() with stored card

Source: https://github.com/creagia/laravel-redsys

Uses a stored RedsysCard for a future transaction, forcing payMethods to PayMethod::Card. The example retrieves the first card from a paying model and passes it with CofType::Recurring.

```php
public function usingCard(CofType $cofType, RedsysCard $redsysCard): RequestBuilder
```

```php
$redsysCard = $payingModel->redsysCards()->first();

$builder = RequestBuilder::newRequest(new RequestParameters(
    amountInCents: 19_99,
    currency: Currency::EUR,
    transactionType: TransactionType::Autorizacion,
))->usingCard(CofType::Recurring, $redsysCard);
```

--------------------------------

### Access stored cards and display number and expiration

Source: https://github.com/creagia/laravel-redsys

```php
$redsysCard = $team->redsysCards()->latest()->first();

foreach ($user->redsysCards as $card) {
    echo $card->number.' '.$card->formattedExpiration();
}
```

--------------------------------

```php
public function requestingCardToken(CofType $cofType): RequestBuilder
```

```php
$redsysRequest = RequestBuilder::newRequest($params)
    ->associateWithModel($productModel)
    ->requestingCardToken(CofType::Recurring)
    ->storeCardOnModel($userModel);
```

use Creagia\Redsys\Enums\CofType;
use Creagia\Redsys\Enums\PayMethod;

/**
 * Use this example for a custom request, optionally associating the request to Eloquent models
 */
public function initialCustomRequest()
{
    $redsysRequest = RequestBuilder::newRequest(new RequestParameters(
        amountInCents: 19_99,
        currency: Currency::EUR,
        transactionType: TransactionType::Autorizacion,
    ))->associateWithModel(
        $yourProductModel
    )->requestingCardToken(
        CofType::Recurring
    )->storeCardOnModel(
        $yourPayingModel // User, Team, ...
    );
    return $redsysRequest->redirect();
}
```

--------------------------------

### Suggested catch strategy for multiple exceptions

Source: https://github.com/creagia/laravel-redsys

Recommended pattern for catching RedsysConfigError, RedsysRequestNotFound, and InvalidRedsysResponseException together, with a \Throwable fallback. This handles specific configuration, lookup, and signature problems before falling back to a generic catch-all.

```php
use Creagia\LaravelRedsys\Exceptions\RedsysConfigError;
use Creagia\LaravelRedsys\Exceptions\RedsysRequestNotFound;
use Creagia\Redsys\Exceptions\InvalidRedsysResponseException;

try {
    $builder->post();
} catch (RedsysConfigError | RedsysRequestNotFound | InvalidRedsysResponseException $e) {
    // handle specific configuration / lookup / signature problems
} catch (\Throwable $e) {
    // fallback
}
```

--------------------------------

### Basic redirect flow with createRedsysRequest()

Source: https://github.com/creagia/laravel-redsys

Creates a Redsys request with a product description and Bizum payment method, then redirects to Redsys. The request is automatically associated with the order model.

// Basic redirect flow
public function checkout()
{
    $redsysRequest = $this->order->createRedsysRequest(
        productDescription: 'Product description',
        payMethod: PayMethod::Bizum,
    );
    return $redsysRequest->redirect();
}
```

--------------------------------

### Publish config file

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

Publish the package configuration file to your application's config directory.

```bash
php artisan vendor:publish --tag="redsys-config"
```

--------------------------------

### RedsysPayable interface definition

Source: https://github.com/creagia/laravel-redsys

use Illuminate\Database\Eloquent\Model;

/**
 * @mixin Model
 */
interface RedsysPayable
{
    public function getTotalAmount(): int;

    $redsysRequest = $yourProductModel->createRedsysRequest(
        productDescription: 'Product description',
        payMethod: PayMethod::Card,
    )->requestingCardToken(
        CofType::Recurring
    )->storeCardOnModel(

### RedsysLocalGatewayController index method

Source: https://github.com/creagia/laravel-redsys

Local fake gateway index. Throws \Exception('Local Gateway is only available on local environment. Update your .env file.') when app is not in local environment. Otherwise decodes Ds_MerchantParameters (base64 + url-decode + JSON) and returns redsys::localGateway view with originalPost and params.

```php
public function index(Request $request): View
```

--------------------------------

### Required .env variables

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

Define at least these environment variables in your .env file for the package to work.

```plaintext
REDSYS_ENVIRONMENT
REDSYS_MERCHANT_CODE
REDSYS_KEY
```

--------------------------------

### Create payment request and redirect

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

Use this snippet to create a Redsys payment request from an Eloquent model and redirect the user to the payment gateway. The method `createRedsysRequest` is called on the model, with a product description and payment method (e.g., Bizum). The `redirect()` method returns the redirect response.

```php
public function createPaymentAndRedirect()
{
    $redsysRequest = $yourModel->createRedsysRequest(
        productDescription: 'Product description',
        payMethod: PayMethod::Bizum,
    );
    return $redsysRequest->redirect();
}
```

--------------------------------

### Creating a notification log entry

Source: https://github.com/creagia/laravel-redsys

Shows how to create a RedsysNotificationLog row from a processed response. Handles both PostRequestError and RedsysResponse by selecting the appropriate parameters array.

```php
$redsysNotificationLog = RedsysNotificationLog::create([
    'merchant_parameters' => $response instanceof PostRequestError
        ? $response->responseParameters
        : $response->merchantParametersArray,
]);
```

--------------------------------

### model() method signature

Source: https://github.com/creagia/laravel-redsys

Returns a polymorphic relation to the owning model. The migration uses `nullableMorphs('model')`.

```php
public function model(): MorphTo
```

--------------------------------

### POST /redsys/localGateway/realizarPago

Source: https://github.com/creagia/laravel-redsys

Local gateway payment initiation endpoint. Handles payment requests via the local gateway controller.

```APIDOC
## [POST] /redsys/localGateway/realizarPago

### Description
Local gateway payment initiation endpoint. Handles payment requests via the local gateway controller.

### Method
POST

### Endpoint
/redsys/localGateway/realizarPago

### Parameters
No parameters documented.

### Response

```

--------------------------------

### post() method signature

Source: https://github.com/creagia/laravel-redsys

Public method that returns a RedsysResponse on success or a PostRequestError when the bank returns an HTTP error. It persists the request, sends the POST request via sendPostRequest(), and runs the HandleRedsysResponse action to update status and fire events.

```php
public function post(): RedsysResponse|PostRequestError

```

--------------------------------

### Send Redsys request via redirection (PayMethod::Card)

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

Creates a Redsys request from your model and redirects the user to the payment gateway. Use this for the Redirection integration method. The method `createRedsysRequest` is expected on your model and `redirect()` sends the user to Redsys.

```php
use Creagia\Redsys\Enums\PayMethod;

public function redirection()
{
    $redsysRequest = $yourModel->createRedsysRequest(
        productDescription: 'Product description',
        payMethod: PayMethod::Card,
    );
    return $redsysRequest->redirect();
}
```

--------------------------------

### Override redirect routes in config file

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

Configuration keys to override the default successful and unsuccessful payment routes. Set these in the package config file to customize where Redsys redirects users after payment. The values default to null, meaning the package's built-in simple views are used.

```php
'successful_payment_route_name' => env('REDSYS_SUCCESSFUL_ROUTE_NAME', null),
'unsuccessful_payment_route_name' => env('REDSYS_UNSUCCESSFUL_ROUTE_NAME', null),
```

--------------------------------

### RedsysNotificationController __invoke method

Source: https://github.com/creagia/laravel-redsys

Handles incoming bank notification POST. Dispatches RedsysNotificationEvent, builds RedsysClient, constructs RedsysResponse, sets parameters from response, finds Request by order_number, and runs HandleRedsysResponse. Throws DeniedRedsysPaymentResponseException, RedsysRequestNotFound, InvalidRedsysResponseException, ErrorRedsysResponseException, RedsysConfigError.

```php
public function __invoke(HttpRequest $httpRequest, CreateRedsysClient $createRedsysClient): void
```

--------------------------------

### Catching RedsysConfigError in consumer code

Source: https://github.com/creagia/laravel-redsys

Shows how to catch RedsysConfigError when calling RequestBuilder::newRequest($params)->post(). The exception is thrown when config('redsys.environment'), config('redsys.tpv.merchantCode'), or config('redsys.tpv.key') is falsy. Mitigation involves setting REDSYS_ENVIRONMENT, REDSYS_MERCHANT_CODE, and REDSYS_KEY environment variables.

```php
use Creagia\LaravelRedsys\Exceptions\RedsysConfigError;

try {
    $response = RequestBuilder::newRequest($params)->post();
} catch (RedsysConfigError $e) {
    // "Missing Environment option from Redsys config" etc.
    report($e->getMessage());
}
```

--------------------------------

### RedsysRequest Facade class

Source: https://github.com/creagia/laravel-redsys

Facade that forwards to the 'redsys-request' container binding and proxies methods of the upstream RedsysRequest via @mixin. Note: the provider does not register this binding in the shown source, so the facade requires manual binding.

```php
/**
 * @mixin \Creagia\Redsys\RedsysRequest
 */
class RedsysRequest extends Facade
{
    protected static function getFacadeAccessor()
    {
        return 'redsys-request';
    }
}
```

--------------------------------

### CreateRedsysClient __invoke() signature

Source: https://github.com/creagia/laravel-redsys

Invokable method that returns a configured RedsysClient. Throws RedsysConfigError::missingOption if environment, merchantCode, or key config options are missing. Uses Environment::Custom with the localGateway URL when environment is 'local'.

```php
public function __invoke(): RedsysClient
```

--------------------------------

### post()

Source: https://github.com/creagia/laravel-redsys

Sends the payment request to the bank and returns the response or an error object. Persists the request, sends the POST request, and processes the response.

```APIDOC
## post()

### Description
Sends the payment request to the bank and returns the response or an error object. Persists the request, sends the POST request, and processes the response.

try {
    $response = $builder->post();
    if ($response instanceof \Creagia\Redsys\Support\PostRequestError) {
        // transport error response: $response->message, $response->code
    }
} catch (\Exception $e) {
    // handled by HandleRedsysResponse / upstream exceptions
}
```
```

--------------------------------

### Prepare Eloquent model with InteractsWithRedsysCards

Source: https://github.com/creagia/laravel-redsys/blob/main/README.md

### RequestBuilder::__construct

Source: https://github.com/creagia/laravel-redsys

Constructor for the RequestBuilder class. Instantiating directly requires dependent services to be resolved from the container, so the static factory newRequest() is the intended public construction path. It initializes the request parameters and fills in default values for order, merchantUrl, urlOk, and urlKo if not set.

```APIDOC
## RequestBuilder::__construct

### Description
Constructor for the RequestBuilder class. Instantiating directly requires dependent services to be resolved from the container, so the static factory newRequest() is the intended public construction path. It initializes the request parameters and fills in default values for order, merchantUrl, urlOk, and urlKo if not set.

### Method
Constructor

### Signature
```php
public function __construct(
    RequestParameters $requestParameters,
)
```

### Parameters
- **requestParameters** (\Creagia\Redsys\Support\RequestParameters) - Required - Object holding all Redsys input parameters. Required fields for a valid transaction at least include `amountInCents`, `currency`, `transactionType` and (unless explicitly set) `order`, `merchantUrl`, `urlOk`, `urlKo`.

### Behavior During Construction
- If `requestParameters->order` is not set (empty), it is filled with `(string) Request::getNextOrderNumber()`.
- If `requestParameters->merchantUrl` is not set, it is filled with `action(\Creagia\LaravelRedsys\Controllers\RedsysNotificationController::class)` (the package notification route).
- If `requestParameters->urlOk` is not set, it is filled with `route(config('redsys.successful_payment_route_name'), $this->uuid)` when that config route name is set, otherwise `action(RedsysSuccessfulPaymentViewController::class, $this->uuid)`.
- If `requestParameters->urlKo` is not set, it is filled analogously using `config('redsys.unsuccessful_payment_route_name')` or `action(RedsysUnsuccessfulPaymentViewController::class, $this->uuid)`.
- A new `uuid` (string) is generated via `Str::uuid()`.
- `RedsysRequest::create($createClient(), $requestParameters)` builds the underlying upstream request using a `CreateRedsysClient`.
```
