TaxJar SDK

This library provides integration support with the TaxJar API.

Prerequisites

To use the TaxJar SDK, you must obtain a TaxJar API token.

Getting Started

We suggest you use Composer to install the TaxJar SDK, well, because it's simple. Just do this:

Create or add to your existing composer.json file:

{
    "require": {
        "okanjo/taxjar": "*"
    }
}

Then do the install or update by:

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar install

And use the Composer autoloader to include everything like magic:

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

$api = new TaxJar\Api\Client('YOUR_API_KEY');

// ...

Smart Sales Tax

$res = $api->getSalesTax()->where(
    array(
        \TaxJar\Api\Common\Fields::AMOUNT => "10.00",
        \TaxJar\Api\Common\Fields::SHIPPING => "2.00",

        \TaxJar\Api\Common\Fields::FROM_CITY => "Ramsey",
        \TaxJar\Api\Common\Fields::FROM_STATE => "NJ",
        \TaxJar\Api\Common\Fields::FROM_ZIP => "07446",
        \TaxJar\Api\Common\Fields::FROM_COUNTRY => "US",

        \TaxJar\Api\Common\Fields::TO_CITY => "Freehold",
        \TaxJar\Api\Common\Fields::TO_STATE => "NJ",
        \TaxJar\Api\Common\Fields::TO_ZIP => "07728",
        \TaxJar\Api\Common\Fields::TO_COUNTRY => "US",
    )
)->execute();

// Note: You can switch from associative de-serialization (default)
//       to objects (do execute(false) instead)

if ($res->status == \TaxJar\Api\Response::HTTP_OK) {
    $amountToCollect = $res->data['amount_to_collect'];
} else {
    // API response was wonky
}

print_r($res);
