This is a PHP sample demonstrating the AvaTax REST API methods: tax/get POST, tax/get GET, tax/cancel POST, and address/validate GET.
For more information on the use of these methods and the AvaTax product, please visit our developer site or homepage
- PHP 5.3 or later (not tested on versions older than PHP 5.3)
- cURL has to be installed on the server before the HTTP REST Request can be made from PHP. Some PHP installations come with cURL, but others need to be installed manually. Try running curl --help from any command line on the server you have PHP installed to see if cURL is working. If cURL is not, you can manually install it from this URL : http://curl.haxx.se
- A Root Certificate needs to be installed for cURL to work. You have to save the root CRT file into a folder on your server and configure cURL to use that exact certificate. Instructions for downloading it can be found here : http://developer.avalara.com/api-docs/designing-your-integration/errors-and-outages/ssl-certificates
-
Authentication requires an valid Account Number and License Key, which should be entered in the test file (e.g. GetTaxTest.php) you would like to run.

If you do not have an AvaTax account, a free trial account can be acquired through our developer site

Some Windows users have had trouble with cURL automatically using our SSL certificate. The sample code offers two workarounds (both in /AvaTaxClasses/classes/TaxServiceRest.php.class). If this is something that presents a challenge for your system, uncomment ONE of the following two options in that file:
//Some Windows users have had trouble with our SSL Certificates. Uncomment the following line to NOT use SSL. // *This is not recommended, see below for better alternative* //curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); //Other Windows users may prefer to download the certificate from our site (detail here: http://developer.avalara.com/api-docs/designing-your-integration/errors-and-outages/ssl-certificates) and manually set the cert path. // To set the path manually, uncomment the following two lines and ensure you are telling curl where it can find the root certificate. If you choose to manually set the path, make sure you have reenabled cURL by commenting out the line above // that tells curl to NOT use SSL. //$ca = "C:/curl/curl-ca-bundle.crt"; //curl_setopt($curl, CURLOPT_CAINFO, $ca);

If you would like to use these core classes as part of a project and manage your depencies through composer, the Avatax classes can be added to your existing project by adding
"repositories": [
{
"type": "vcs",
"url": "https://github.com/avadev/AvaTax-Calc-REST-PHP"
}
],
"require": {
"avalara/avatax": "*"
}
to your composer.json file and run php composer.phar update
from your command line.
