SparkPost PHP Library

The official PHP library for using the SparkPost REST API.

Before using this library, you must have a valid API Key. To get an API Key, please log in to your SparkPost account and generate one in the Settings page.

Installation

Please note: The composer package sparkpost/php-sparkpost has been changed to sparkpost/sparkpost starting with version 2.0.

The recommended way to install the SparkPost PHP Library is through composer.

# Install Composer
curl -sS https://getcomposer.org/installer | php

Sparkpost requires php-http client (see Setting up a Request Adapter). There are several providers available. If you were using guzzle6 your install might look like this.

composer require guzzlehttp/guzzle
composer require php-http/guzzle6-adapter

Next, run the Composer command to install the SparkPost PHP Library:

composer require sparkpost/sparkpost

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';
use SparkPost\SparkPost;

Setting up a Request Adapter

Because of dependency collision, we have opted to use a request adapter rather than requiring a request library. This means that your application will need to pass in a request adapter to the constructor of the SparkPost Library. We use the HTTPlug in SparkPost. Please visit their repo for a list of supported clients and adapters. If you don't currently use a request library, you will need to require one and create a client from it and pass it along. The example below uses the GuzzleHttp Client Library.

An Client can be setup like so:

<?php
require 'vendor/autoload.php';

use SparkPost\SparkPost;
use GuzzleHttp\Client;
use Http\Adapter\Guzzle6\Client as GuzzleAdapter;

$httpClient = new GuzzleAdapter(new Client());
$sparky = new SparkPost($httpClient, ['key'=>'YOUR_API_KEY']);
?>

Examples

Send An Email Using The Transmissions Endpoint

<?php
require 'vendor/autoload.php';

use SparkPost\SparkPost;
use GuzzleHttp\Client;
use Http\Adapter\Guzzle6\Client as GuzzleAdapter;

$httpClient = new GuzzleAdapter(new Client());
$sparky = new SparkPost($httpClient, ['key'=>'YOUR_API_KEY']);

$sparky = new SparkPost($httpClient, $options);
$promise = $sparky->transmissions->post([
    'content' => [
        'from' => [
            'name' => 'SparkPost Team',
            'email' => '[email protected]',
        ],
        'subject' => 'First Mailing From PHP',
        'html' => '<html><body><h1>Congratulations, {{name}}!</h1><p>You just sent your very first mailing!</p></body></html>',
        'text' => 'Congratulations, {{name}}!! You just sent your very first mailing!',
    ],
    'substitution_data' => ['name' => 'YOUR_FIRST_NAME'],
    'recipients' => [
        [
            'address' => [
                'name' => 'YOUR_NAME',
                'email' => 'YOUR_EMAIL',
            ],
        ],

            ],
        ],
    ],
]);

Send An API Call Using The Base Request Function

We provide a base request function to access any of our API resources.

<?php
require 'vendor/autoload.php';

use SparkPost\SparkPost;
use GuzzleHttp\Client;
use Http\Adapter\Guzzle6\Client as GuzzleAdapter;

$httpClient = new GuzzleAdapter(new Client());
$sparky = new SparkPost($httpClient, ['key'=>'YOUR_API_KEY']);

$promise = $sparky->request('GET', 'metrics/ip-pools', [
    'from' => '2014-12-01T09:00',
    'to' => '2015-12-01T08:00',
    'timezone' => 'America/New_York',
    'limit' => '5',
]);

Handling Responses

The API calls either return a SparkPostPromise or SparkPostResponse depending on if async is true or false

Synchronous

$sparky->setOptions(['async' => false]);
try {
    $response = $sparky->transmissions->get();
    
    echo $response->getStatusCode()."\n";
    print_r($response->getBody())."\n";
}
catch (\Exception $e) {
    echo $e->getCode()."\n";
    echo $e->getMessage()."\n";
}

Asynchronous

Asynchronous an be handled in two ways: by passing callbacks or waiting for the promise to be fulfilled. Waiting acts like synchronous request.

Wait (Synchronous)

$promise = $sparky->transmissions->get();

try {
    $response = $promise->wait();
    echo $response->getStatusCode()."\n";
    print_r($response->getBody())."\n";
} catch (\Exception $e) {
    echo $e->getCode()."\n";
    echo $e->getMessage()."\n";
}

echo "I will print out after the promise is fulfilled";

Then (Asynchronous)

$promise = $sparky->transmissions->get();

$promise->then(
    // Success callback
    function ($response) {
        echo $response->getStatusCode()."\n";
        print_r($response->getBody())."\n";
    },
    // Failure callback
    function (Exception $e) {
        echo $e->getCode()."\n";
        echo $e->getMessage()."\n";
    }
);

echo "I will print out before the promise is fulfilled";

Handling Exceptions

An exception will be thrown in two cases: there is a problem with the request or the server returns a status code of 400 or higher.

SparkPostException

• getCode()
  • Returns the response status code of 400 or higher
• getMessage()
  • Returns the exception message
• getBody()
  • If there is a response body it returns it as an Array. Otherwise it returns null.
