Getting Started with PagarmeApiSDK

Introduction

Pagarme API

Building

The generated code has dependencies over external libraries like UniRest and JsonMapper. JsonMapper requires docblock annotations like @var, @maps, and @factory to map JSON responses with our class definitions. Hence the docblocks in generated code cannot be disabled by deactivating the PHP configurations like opcache.save_comments. 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.

Building SDK - Step 1

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.
[curl]; A default value for the CURLOPT_CAINFO option. This is required to be an
; absolute path.
curl.cainfo = PATH_TO/cacert.pem

Installation

The following section explains how to use the PagarmeApiSDKLib 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.

Open project in PHPStorm - Step 1

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

Open project in PHPStorm - Step 2

2. Add a new Test Project

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

Add a new project in PHPStorm - Step 1

Name the directory as "test".

Add a new project in PHPStorm - Step 2

Add a PHP file to this project.

Add a new project in PHPStorm - Step 3

Name it "testSDK".

Add a new project in PHPStorm - Step 4

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

require_once "vendor/autoload.php";

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

Add a new project in PHPStorm - Step 5

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.

Run Test Project - Step 1

Select PHP from within Languages & Frameworks.

Run Test Project - Step 2

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

Run Test Project - Step 3

Once the interpreter is selected, click OK.

Run Test Project - Step 4

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

Run Test Project - Step 5

Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

Parameter Type Description
serviceRefererName string
timeout int Timeout for API calls in seconds.
Default: 0
enableRetries bool Whether to enable retries and backoff feature.
Default: false
numberOfRetries int The number of retries to make.
Default: 0
retryInterval float The retry time interval between the endpoint calls.
Default: 1
backOffFactor float Exponential backoff factor to increase interval between retries.
Default: 2
maximumRetryWaitTime int The maximum wait time in seconds for overall retrying requests.
Default: 0
retryOnTimeout bool Whether to retry on request timeout.
Default: true
httpStatusCodesToRetry array Http status codes to retry against.
Default: 408, 413, 429, 500, 502, 503, 504, 521, 522, 524
httpMethodsToRetry array Http methods to retry against.
Default: 'GET', 'PUT'
basicAuthCredentials BasicAuthCredentials The Credentials Setter for Basic Authentication

The API client can be initialized as follows:

$client = PagarmeApiSDKClientBuilder::init()
    ->basicAuthCredentials(
        BasicAuthCredentialsBuilder::init(
            'BasicAuthUserName',
            'BasicAuthPassword'
        )
    )
    ->serviceRefererName('ServiceRefererName')
    ->build();

Authorization

This API uses the following authentication schemes.

API Errors

Here is the list of errors that the API might throw.

HTTP Status Code Error Description Exception Class
400 Invalid request ErrorException
401 Invalid API key ErrorException
404 An informed resource was not found ErrorException
412 Business validation error ErrorException
422 Contract validation error ErrorException
500 Internal server error ErrorException
