API v1 Quickstart

This page provides a quick introduction to Chargify SDK for PHP and introductory examples for v1 of the Chargify API. If you have not already installed the SDK, head over to the Installation page.

Making a Request

The first step to sending a request with the SDK is to create a Crucial\Service\Chargify object.

Creating an API Client

<?php
use Crucial\Service\Chargify;

$chargify = new Chargify([
    'hostname'   => 'yoursubdomain.chargify.com',
    'api_key'    => '{{API_KEY}}',
    'shared_key' => '{{SHARED_KEY}}'
]);

The client constructor accepts an associative array of options:

hostname
(string) The hostname of the Chargify site you want to interact with.
api_key
(string) API key from your Chargify site.
shared_key
(string) Shared key from your Chargify site.

See the Chargify documentation for help finding your API v1 credentials.

Resource Objects

The Chargify API v1 is divided into resources such as subscriptions, customers, products, etc. The SDK follows this same pattern and provides a simple interface for selecting the resource you want to operate on.

<?php
use Crucial\Service\Chargify;

$chargify = new Chargify([
    'hostname'   => 'yoursubdomain.chargify.com',
    'api_key'    => '{{API_KEY}}',
    'shared_key' => '{{SHARED_KEY}}'
]);

// Crucial\Service\Chargify\Customer
$customer = $chargify->customer();

// Crucial\Service\Chargify\Subscription
$subscription = $chargify->subscription();

// Crucial\Service\Chargify\Product
$product = $chargify->product();

// Crucial\Service\Chargify\Adjustment
$adjustment = $chargify->adjustment();

// Crucial\Service\Chargify\Charge
$charge = $chargify->charge();

// Crucial\Service\Chargify\Component
$component = $chargify->component();

// Crucial\Service\Chargify\Coupon
$coupon = $chargify->coupon();

// Crucial\Service\Chargify\Transaction
$transaction = $chargify->transaction();

// Crucial\Service\Chargify\Refund
$refund = $chargify->refund();

// Crucial\Service\Chargify\Statement
$statement = $chargify->statement();

// Crucial\Service\Chargify\Event
$event = $chargify->event();

// Crucial\Service\Chargify\Webhook
$webhook = $chargify->webhook();

// Crucial\Service\Chargify\Stats
$stats = $chargify->stats();

Sending Requests

Now that you have a resource object you’re ready to send a request. The resource objects provide a fluent interface for setting properties to send in your request. The example below shows how to create a new customer.

<?php
use Crucial\Service\Chargify;

$chargify = new Chargify([
    'hostname'   => 'yoursubdomain.chargify.com',
    'api_key'    => '{{API_KEY}}',
    'shared_key' => '{{SHARED_KEY}}'
]);

// Crucial\Service\Chargify\Customer
$customer = $chargify->customer()
    // set customer properties
    ->setFirstName('Dan')
    ->setLastName('Bowen')
    ->setEmail('dan@mailinator.com')
    // send the create request
    ->create();

Using Responses

In the previous example, calling ->create() on the Crucial\Service\Chargify\Customer object will send the request to Chargify and load it with the newly created customer response.

You can access the response data as you would any normal array:

$customerId = $customer['id']; // Chargify customer ID
$firstName  = $customer['first_name'];
$lastName   = $customer['last_name'];
$email      = $customer['email'];

Error Handling

The SDK loads errors on the resource object for any errors that occur during a transfer.

  • You can test for an error using the ->isError() method of the resource object.

    if ($customer->isError()) {
       // handle errors
    } else {
       // the transfer was successful
       $customerId = $customer['id']; // Chargify customer ID
       $firstName  = $customer['first_name'];
       $lastName   = $customer['last_name'];
       $email      = $customer['email'];
    }
    
  • You can get the loaded errors, if any, using the ->getErrors() method of the resource object.

    if ($customer->isError()) {
       // array of errors loaded during the transfer
       $errors = $customer->getErrors();
    }
