Unofficial Laravel SDK for E-cash

A basic and simple package that aims to simplify the goal of integrating Ecash payment system into Laravel.

Installation

You can install the package via composer:

composer require ixcoders/laravel-ecash-sdk

You can publish the config file with:

php artisan vendor:publish --provider="IXCoders\\LaravelEcash\\LaravelEcashServiceProvider" --tag="config"

This is the contents of the published config file:

// config for IXCoders/LaravelEcash

return [
    /**
     * Checkout types
     *
     * Defines the available checkout types for the system.
     */
    "checkout_types" => [
        "CARD",
        "QR"
    ],

    /**
     * Terminal key
     *
     * Defines the terminal key which will be used.
     */
    "terminal_key" => env("ECASH_TERMINAL_KEY"),

    /**
     * Merchant ID
     *
     * Defines the Merchant ID of the account that will be used.
     */
    "merchant_id"   =>  env("ECASH_MERCHANT_ID"),

    /**
     * Merchant secret
     *
     * Defines the secret key that links to the merchant account.
     */
    "merchant_secret" => env("ECASH_MERCHANT_SECRET"),

    /**
     * Currencies
     *
     * Defines the currencies that are currently supported by the system.
     */
    "currencies" => ["SYP"],

    /**
     * Redirect route
     *
     * Defines the name of the route which the user will be redirected to after the operation ends.
     */
    "redirect_route" => "ecash.redirect",

    /**
     * Callback route
     *
     * Defines the name of the route which will be called upon the operation finish.
     */
    "callback_route" => "ecash.callback"
];

Configuration

This package requires from you to setup a number of parameters and confguration values before proceeding with its usage and they all can be found in the configuration file laravel-ecash-sdk.php, let's take a look at them:

• terminal_key — Defines the terminal key which will be used. This value can be configured by setting the environment variable ECASH_TERMINAL_KEY.
• merchant_id — Defines the Merchant ID of the account that will be used. This value can be configured by setting the environment variable ECASH_MERCHANT_ID.
• merchant_secret — Defines the secret key that links to the merchant account. This value can be configured by setting the environment variable ECASH_MERCHANT_SECRET.
• redirect_route — Defines the name of the route which the user will be redirected to after the operation ends. You can either define a route named ecash.redirect in your routes file, or you can set the environment variable ECASH_REDIRECT_URL.
• callback_route — Defines the name of the route which will be called upon the operation finish. You can either define a route named ecash.callback in your routes file, or you can set the environment variable ECASH_CALLBACK_URL.

Note: The package will first look for the named routes and check if they're defined, if yes then it will use them, if no then it will look for the environment variables, if they're defined it will use them, if not then it will throw a MissingRouteException exception. Just remember that named routes has a higher priority.

Usage

There are many ways you can use the package, let's take a look at each one.

• Use the LaravelEcash facade:

use IXCoders\LaravelEcash\Facades\LaravelEcash;

$verificationCode = LaravelEcash::getVerificationCode($amount, $reference);

• Obtain an instance out of the service container:

$object = app("ecash.laravel");
$verificationCode = $object->getVerificationCode($amount, $reference);

• Create an instance of IXCoders\LaravelEcash\LaravelEcash manually (not recommended):

$object = new IXCoders\LaravelEcash\LaravelEcash();
$verificationCode = $object->getVerificationCode($amount, $reference);

Available functionality

The core of the package is the class IXCoders\LaravelEcash\LaravelEcash, and it defines the following methods for public usage:

class LaravelEcash {

    public function getVerificationCode(int $amount, string $reference): string;

    public function checkVerificationCode(string $hash, int $amount, string $reference): bool

    public function generatePaymentLink(string $checkout_type, int $amount, string $reference, string $currency = "SYP", ?string $language = NULL): string;

}

Most of the time, you will use the generatePaymentLink() method.

This package can also throw a number of exceptions in unfortunate circumstances, and they all lies under the namespace IXCoders\LaravelEcash\Exceptions:

• InvalidAmountException — Thrown upon the insertion of incorrect amount to be processed.
• InvalidCheckoutTypeException — Thrown if an invalid checkout type has been passed.
• InvalidCurrencyException — Thrown if an invalid currency has been passed.
• InvalidOrMissingConfigurationValueException — Thrown if the configuration file contains invalid or missing configuration values that are necessary for the package to function correctly.
• MissingRouteException — Thrown if a route couldn't be found for redirect and callback. Please check the configuration section on routes for further information.
