dwolla-php

The new and improved Dwolla library based off of the Guzzle REST client. dwolla-php includes support for all API endpoints, and is the new library officially supported by Dwolla.

Version

2.0.9

Installation

dwolla-php is available on Packagist, and therefore can be installed automagically via Composer.

The PHP JSON and CURL extensions are required for dwolla-php to operate.

To install without adding to composer.json:

composer require dwolla/dwolla-php

To add to composer.json and make this a permanent dependency of your package:

composer require "dwolla/dwolla-php=2.*"
composer update && composer install

Quickstart

dwolla-php makes it easy for developers to hit the ground running with our API. Before attempting the following, you should ideally create an application key and secret.

• Set any variables in _settings.php or the Settings class. All fields are public.
• Instantiate dwolla-php with the class that contains the endpoints you require.
• Use at will!

Use variables in _settings.php

require '../lib/account.php';
$Account = new Dwolla\Account();

/**
 * Example 1: Get basic information for
 * a Dwolla user using their Dwolla ID.
 */
print_r($Account->basic('812-121-7199'));

Set your own

See accountInst.php for an example of the following.

require '../lib/account.php';
$Account = new Dwolla\Account();

$Account->settings->client_id = "MY KEY";
$Account->settings->client_secret = "MY SECRET";
$Account->settings->sandbox = true;

/**
 * Example 1: Get basic information for
 * a Dwolla user using their Dwolla ID.
 */
print_r($Account->basic('812-121-7199'));

---

There are 8 quickstart files which will walk you through working with dwolla-php's classes/endpoint groupings.

• account.php: Retrieve account information, such as balance.
• checkouts.php: Offsite-gateway endpoints, server-to-server checkout example.
• contacts.php: Retrieve/sort through user contacts.
• fundingSources.php: Modify and get information with regards to funding sources.
• masspay.php: Create and retrieve jobs/data regarding MassPay jobs.
• oauth.php: Examples on retrieving OAuth access/refresh token pairs.
• requests.php: Create and retrieve money requests/information regarding money requests.
• transactions.php: Send money, get transaction info by ID, etc.

Structure

dwolla-php is a conglomerate of multiple classes; each file in the lib/ directory contains a class which contains all the endpoints for that certain category (similar to Dwolla's developer documentation).

Endpoint Classes / Methods

Each endpoint class extends RestClient located in client.php (e.g. RestClient::Account()).

• get(): Gets status of existing checkout session.
• complete(): Completes a checkout session.
• verify(): Verifies a checkout session.

Internal Use

client.php/RestClient() is the base class for all of the aforementioned classes, _settings.php/Settings() does not inherit from anything and only contains configuration parameters.

Unit Testing

dwolla-php uses PHPUnit for unit testing. These tests do not test integration and will occassionally show console API errors due to 'dummy' data being used. Integration testing is planned sometime in the future.

To run the tests, install require\dev from composer.json and run:

cd tests
../vendor/bin/phpunit
