Getting Started with PagarmeApiSDK

Introduction

Pagarme API

Building

The generated code depends on a few Ruby gems. The references to these gems are added in the gemspec file. The easiest way to resolve the dependencies, build the gem and install it is through Rake:

1. Install Rake if not already installed: gem install rake
2. Install Bundler if not already installed: gem install bundler
3. From terminal/cmd navigate to the root directory of the SDK.
4. Invoke: rake install

Alternatively, you can build and install the gem manually:

1. From terminal/cmd navigate to the root directory of the SDK.
2. Run the build command: gem build pagarme_api_sdk.gemspec
3. Run the install command: gem install pagarme_api_sdk-6.8.15.gem

Installation

The following section explains how to use the pagarme_api_sdk ruby gem in a new Rails project using RubyMine™. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

1. Starting a new project

Close any existing projects in RubyMine™ by selecting File -> Close Project. Next, click on Create New Project to create a new project from scratch.

Next, provide TestApp as the project name, choose Rails Application as the project type, and click OK.

In the next dialog make sure that the correct Ruby SDK is being used (>= 2.6 and <= 3.2) and click OK.

2. Add reference of the gem

In order to use the pagarme_api_sdk gem in the new project we must add a gem reference. Locate the Gemfile in the Project Explorer window under the TestApp project node. The file contains references to all gems being used in the project. Here, add the reference to the library gem by adding the following line: gem 'pagarme_api_sdk', '6.8.15'

3. Adding a new Rails Controller

Once the TestApp project is created, a folder named controllers will be visible in the Project Explorer under the following path: TestApp > app > controllers. Right click on this folder and select New -> Run Rails Generator....

Selecting the said option will popup a small window where the generator names are displayed. Here, select the controller template.

Next, a popup window will ask you for a Controller name and included Actions. For controller name provide Hello and include an action named Index and click OK.

A new controller class named HelloController will be created in a file named hello_controller.rb containing a method named Index.

1. Add the require 'pagarme_api_sdk' statement to require the gem in the controller file.
2. Add the include PagarmeApiSdk statement to include the sdk module in the controller file.
3. In the Index method, add code for initialization and a sample for its usage.

Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

timeout	Float	The value to use for connection timeout. Default: 60
max_retries	Integer	The number of times to retry an endpoint call if it fails. Default: 0
retry_interval	Float	Pause in seconds between retries. Default: 1
backoff_factor	Float	The amount to multiply each successive retry's interval amount by in order to provide backoff. Default: 2
retry_statuses	Array	A list of HTTP statuses to retry. Default: [408, 413, 429, 500, 502, 503, 504, 521, 522, 524]

http_callback	HttpCallBack	The Http CallBack allows defining callables for pre and post API calls.
basic_auth_credentials	BasicAuthCredentials	The credential object for Basic Authentication

The API client can be initialized as follows:

client = PagarmeApiSdk::Client.new(
  service_referer_name: 'ServiceRefererName',
  basic_auth_credentials: BasicAuthCredentials.new(
    username: 'BasicAuthUserName',
    password: 'BasicAuthPassword'
  )
)
