Getting Started with PagarmeApiSDK

Introduction

Pagarme API

Building

Requirements

The SDK relies on Node.js and npm (to resolve dependencies). It also requires Typescript version >=4.1. You can download and install Node.js and npm from the official Node.js website.

NOTE: npm is installed by default when Node.js is installed.

Verify Successful Installation

Run the following commands in the command prompt or shell of your choice to check if Node.js and npm are successfully installed:

• Node.js: node --version

• npm: npm --version

Install Dependencies

• To resolve all dependencies, go to the SDK root directory and run the following command with npm:

npm install

• This will install all dependencies in the node_modules folder.

Installation

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

1. Initialize the Node Project

• Open an IDE/text editor for JavaScript like Visual Studio Code. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

• Click on File and select Open Folder. Select an empty folder of your project, the folder will become visible in the sidebar on the left.

• To initialize the Node project, click on Terminal and select New Terminal. Execute the following command in the terminal:

npm init --y

2. Add Dependencies to the Client Library

• The created project manages its dependencies using its package.json file. In order to add a dependency on the PagarmeApiSDKLib client library, double click on the package.json file in the bar on the left and add the dependency to the package in it.

• To install the package in the project, run the following command in the terminal:

npm install

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 | number | Timeout for API calls.Default: 0 | | httpClientOptions | Partial<HttpClientOptions> | Stable configurable http client options. | | unstableHttpClientOptions | any | Unstable configurable http client options. | | basicAuthCredentials | BasicAuthCredentials | The credential object for basicAuth |

The API client can be initialized as follows:

Code-Based Client Initialization

import { Client } from 'pagarmeapisdklib';

const client = new Client({
  basicAuthCredentials: {
    username: 'BasicAuthUserName',
    password: 'BasicAuthPassword'
  },
  serviceRefererName: 'ServiceRefererName',
  timeout: 0,
});

Configuration-Based Client Initialization

import * as path from 'path';
import * as fs from 'fs';
import { Client } from 'pagarmeapisdklib';

// Provide absolute path for the configuration file
const absolutePath = path.resolve('./config.json');

// Read the configuration file content
const fileContent = fs.readFileSync(absolutePath, 'utf-8');

// Initialize client from JSON configuration content
const client = Client.fromJsonConfig(fileContent);

See the Configuration-Based Client Initialization section for details.

Environment-Based Client Initialization

import * as dotenv from 'dotenv';
import * as path from 'path';
import * as fs from 'fs';
import { Client } from 'pagarmeapisdklib';

// Optional - Provide absolute path for the .env file
const absolutePath = path.resolve('./.env');

if (fs.existsSync(absolutePath)) {
  // Load environment variables from .env file
  dotenv.config({ path: absolutePath, override: true });
}

// Initialize client using environment variables
const client = Client.fromEnvironment(process.env);

See the Environment-Based Client Initialization section for details.

Authorization

This API uses the following authentication schemes.

• httpBasic (Basic Authentication)

API Errors

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

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