Walmart uses a signature calculation algorithm for authenticating API calls, it is fairly complicated so this library is intended to make it as easy as calling a function.
The easiest way to install this library is using Composer. Simply add the following to your composer.json file:
"fillup/walmart-auth-signature-php": "dev-master"
Or run composer require fillup/walmart-auth-signature-php:dev-master.
This assumes you have composer installed and available in your path
as composer.
This library uses semantic versioning as well as a Git Flow process
for development. Usage of dev-master should be safe as the
master branch is considered production ready.
You can either use Walmart\Auth\Signature class in an object form,
or by calling static methods on it.
If you need to make repeated API calls you can instantiate a Signature
object and simply call the getSignature method to get a new
signature over and over:
<?php
use Walmart\Auth\Signature as AuthSignature;
$authSignature = new AuthSignature($consumerId, $privateKey, $requestUrl, $requestMethod);
$signatureString = $authSignature->getSignature();
// Make your call
// Get a new signature for a new call
$signatureString = $authSignature->getSignature(null,$newUrl);Sometimes just calling a static method is easier or more elegant, here you go:
<?php
use Walmart\Auth\Signature as AuthSignature;
$signatureString = AuthSignature::calculateSignature($consumerId, $privateKey, $requestUrl, $requestMethod);
// Make your call
// Get a new signature for a new call
$signatureString = AuthSignature::calculateSignature($consumerId, $privateKey, $requestUrl, $requestMethod);I appreciate issue reports and pull requests, so if you see opportunity for improvement, please let us know and send us a pull request.
