PayFort PHP SDK

Payfort payment gateway integration library for PHP

1 Setup

1.1 Automatically using composer

Just require it composer require itvisionsy/payfort-php., _(*1)

1.2 Manually using Composer

You will need to add the ItvisionSy\Payment\PayFort\ as a PSR-4 namespace pointing to the path of the library root, and the autoload.php file at the files section. Let us say you have the following structure:, _(*2)

-/              <= Project root
  - Libraries/
    - PayFort/  <= This is the payment library
  composer.json <= The composer.json config file

In the composer.json file, you need to have the following definition:, _(*3)

  "autoload": {
    "psr-4": {
      "ItvisionSy\\Payment\\PayFort\\": "Libraries/PayFort/src/"
    },
    "files": [
      "Libraries/PayFort/autoload.php"
    ]
  }

1.3 Manually using Autoload.php

You will need to require the autoload.php file before using the library., _(*4)

2 Configuration

You can configure the payment in one of following ways: 1. Create a file called payfort_config.php in the server root. This file should return an array of configuration. Following is a sample of the file content. php <?php return [ 'sandbox' => true, 'merchant_identifier' => 'payfort_merchant_identifier_string', 'access_code' => 'payfort_merchant_access_code_here', 'language' => \ItvisionSy\Payment\PayFort\Config::LANG_EN, 'sha_type' => \ItvisionSy\Payment\PayFort\Config::SHA_TYPE_SHA256, 'sha_request_phrase' => 'request_phrase_here', 'sha_response_phrase' => 'response_phrase_here', 'response_url_tokenization' => 'http://your_redirect_back_url_to_receive_tokenization_result', 'response_url_purchase' => 'http://your_redirect_back_url_to_receive_purchase_result', 'response_url_authorization' => 'http://your_redirect_back_url_to_receive_authorize_result', 'send_as_normal_http_post' => true, 'model_loader' => $your_model_loader_callable ]; 1. Before using any function or method of the payment, use the public static method ItvisionSy\Payment\PayFort\Config::setDefaultConfig() and pass an array of the config values. Following is a sample of the usage of this method: php <?php \ItvisionSy\Payment\PayFort\Config::setDefaultConfig([ 'sandbox' => true, 'merchant_identifier' => 'payfort_merchant_identifier_string', 'access_code' => 'payfort_merchant_access_code_here', 'language' => \ItvisionSy\Payment\PayFort\Config::LANG_EN, 'sha_type' => \ItvisionSy\Payment\PayFort\Config::SHA_TYPE_SHA256, 'sha_request_phrase' => 'request_phrase_here', 'sha_response_phrase' => 'response_phrase_here', 'response_url_tokenization' => 'http://your_redirect_back_url_to_receive_tokenization_result', 'response_url_purchase' => 'http://your_redirect_back_url_to_receive_purchase_result', 'response_url_authorization' => 'http://your_redirect_back_url_to_receive_authorize_result', 'send_as_normal_http_post' => true, 'model_loader' => $your_model_loader_callable ]); 1. You can manually initiate a config object and store it in the $GLOBALS array as payfort_config. Following is a sample of this method: php <?php $GLOBALS['payfort_config'] = \ItvisionSy\Payment\PayFort\Config::make() ->setSandbox(true) ->setMerchantIdentifier('payfort_merchant_identifier_string') ->setAccessCode('payfort_merchant_access_code_string') ->setLanguage(\ItvisionSy\Payment\PayFort\Config::LANG_AR) ->setShaType(\ItvisionSy\Payment\PayFort\Config::SHA_TYPE_SHA256) ->setShaRequestPhrase('request_phrase_here') ->setShaResponsePhrase('response_phrase_here') ->setResponseUrlTokenization('http://your_redirect_back_url_to_receive_tokenization_result') ->setResponseUrlPurchase('http://your_redirect_back_url_to_receive_purchase_result') ->setResponseUrlAuthorization('http://your_redirect_back_url_to_receive_authorize_result') ->setSendAsNormalHttpPost(true) ->setModelLoader($your_model_loader_callable); 1. You can define a public helper function called payfort_config which will always return an object of \ItvisionSy\Payment\PayFort\Config. This is an example: php <?php function payfort_config(){ return \ItvisionSy\Payment\PayFort\Config::make() ->setSandbox(true) ->setMerchantIdentifier('payfort_merchant_identifier_string') ->setAccessCode('payfort_merchant_access_code_string') ->setLanguage(\ItvisionSy\Payment\PayFort\Config::LANG_AR) ->setShaType(\ItvisionSy\Payment\PayFort\Config::SHA_TYPE_SHA256) ->setShaRequestPhrase('request_phrase_here') ->setShaResponsePhrase('response_phrase_here') ->setResponseUrlTokenization('http://your_redirect_back_url_to_receive_tokenization_result') ->setResponseUrlPurchase('http://your_redirect_back_url_to_receive_purchase_result') ->setResponseUrlAuthorization('http://your_redirect_back_url_to_receive_authorize_result') ->setSendAsNormalHttpPost(true) ->setModelLoader($your_model_loader_callable); }, _(*5)

3 Usage

3.1 Understand the logic flow

PayFort has two main types of operations: token-based and id-based. * Token-based operations are AUTHORIZE and PURCHASE, which are the ones used to charge credit cards. On success, they return a fort_id string, which is used in id-based operations. * id-based operations are mainly any operation to alter, finish, enquire, or cancel an token-based operation. They are CAPTURE a full or part amount of AUTHORIZE operation, or VOID it. REFUND any captured amount. And other maintenance operations., _(*6)

Token based operations need a token to be generated for specific credit card info. To do this, a full HTTP POST request to be send to PayFort contains the credit card information along side the merchant identification. If succeeded, it will return a token string for this credit card. This token can be used again in later operations for the same user. After that, all the remaining operations are normal HTTP API-call operations, unless there is 3rd party security check, which will require a redirect cycle. Both PURCHASE and AUTHORIZE operations require a token to be used. If you already have a token generated for a user's credit card, you can bypass the tokenization cycle and jump directly to purchase process., _(*7)

3.2 How to use

There are two approaches: 1. Extend the required operation's abstract class and implement the succeeded/failed functions. 1. Call the required operation's implementation and pass the succeeded/failed callables., _(*8)
