Download the PHP package obaidkhattak/pqapiv2 without Composer

Getting Started with PQ API v2

Introduction

Building

The generated code has dependencies over external libraries like UniRest. These dependencies are defined in the composer.json file that comes with the SDK. To resolve these dependencies, we use the Composer package manager which requires PHP greater than or equal to 7.2 installed in your system. Visit https://getcomposer.org/download/ to download the installer file for Composer and run it in your system. Open command prompt and type composer --version. This should display the current version of the Composer installed if the installation was successful.

• Using command line, navigate to the directory containing the generated files (including composer.json) for the SDK.
• Run the command composer install. This should install all the required dependencies and create the vendor directory in your project directory.

Configuring CURL Certificate Path in php.ini

:information_source: Note This is for Windows users only.

CURL used to include a list of accepted CAs, but no longer bundles ANY CA certs. So by default it will reject all SSL certificates as unverifiable. You will have to get your CA's cert and point curl at it. The steps are as follows:

1. Download the certificate bundle (.pem file) from https://curl.haxx.se/docs/caextract.html on to your system.
2. Add curl.cainfo = "PATH_TO/cacert.pem" to your php.ini file located in your php installation. “PATH_TO” must be an absolute path containing the .pem file.

Installation

The following section explains how to use the PQAPIV2Lib library in a new project.

1. Open Project in an IDE

Open an IDE for PHP like PhpStorm. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

Click on Open in PhpStorm to browse to your generated SDK directory and then click OK.

2. Add a new Test Project

Create a new directory by right clicking on the solution name as shown below:

Name the directory as "test".

Add a PHP file to this project.

Name it "testSDK".

Depending on your project setup, you might need to include composer's autoloader in your PHP code to enable auto loading of classes.

It is important that the path inside require_once correctly points to the file autoload.php inside the vendor directory created during dependency installations.

After this you can add code to initialize the client library and acquire the instance of a Controller class. Sample code to initialize the client library and use the Controller methods is given in the subsequent sections.

3. Run the Test Project

To run your project you must set the Interpreter for your project. Interpreter is the PHP engine installed on your computer.

Open Settings from File menu.

Select PHP from within Languages & Frameworks.

Browse for Interpreters near the Interpreter option and choose your interpreter.

Once the interpreter is selected, click OK.

To run your project, right click on your PHP file inside your Test project and click on Run.

Test the SDK

Unit tests in this SDK can be run using PHPUnit.

1. First install the dependencies using composer including the require-dev dependencies.
2. Run vendor\bin\phpunit --verbose from commandline to execute tests. If you have installed PHPUnit globally, run tests using phpunit --verbose instead.

You can change the PHPUnit test configuration in the phpunit.xml file.

Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

The API client can be initialized as follows:
