README

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.

Build Status

Installation

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.

Versioning

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.

Usage

You can either use Walmart\Auth\Signature class in an object form, or by calling static methods on it.

Object interface

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);

Static method interface

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);
