Vend SDK (a PHP client)

An unofficial PHP SDK for the Vend POS API.

Installation

You can install this package via composer:

composer require simplesquid/vend-sdk

Setup

To setup, get the instance of the SDK and set the desired user agent and settings:

$vend = Vend::getInstance();

/* Optional configuration. */
$vend->userAgent('Vend SDK')
     ->requestTimeout(2)
     ->confirmationTimeout(30);

It is advisable that you use the client object as a singleton, however, there is no explicit restriction for this.

Usage

This outlines a typical sequence of instructions, but is not a complete list of all the functionality of the SDK. Please review the code for more advanced usages. It is also suggested you read the Vend API documentation.

Alternatively, you can see a working authorisation implementation in our Laravel Vend SDK package.

Authorisation

You have two options for authorisation with the Vend API, a Personal Access Token or OAuth 2.0.

Personal Access Token

When using the Personal Access Token, simply setup the Vend client like so:

$vend->domainPrefix($domain_prefix)
     ->personalAccessToken($access_token);

OAuth 2.0

Setup the Vend client with the OAuth identifiers:

$vend->clientId($client_id)
     ->clientSecret($client_secret)
     ->redirectUri($redirect);

Initial authorisation procedure

Send the user to the OAuth URL generated by:

$vend->getAuthorisationUrl($previous_url);

Use the domain prefix and authorisation code returned from the OAuth process:

/** @var \SimpleSquid\Vend\Resources\OneDotZero\Token */
$token = $vend->domainPrefix($domain_prefix)
              ->oAuthAuthorisationCode($code);

Make sure you store the returned Token object and the domain prefix.

Subsequent setup procedure

Once you have received the initial authorisation, you may setup the Vend client using the Token object received during the authorisation process:

$vend->authorisationToken($token);

If a request throws a \SimpleSquid\Vend\Exceptions\TokenExpiredException, you can refresh the token like so:

/** @var \SimpleSquid\Vend\Resources\OneDotZero\Token */
$token = $vend->refreshOAuthAuthorisationToken();

Again, make sure you store the returned Token object.

Requests

To see all the available requests, take a look at traits located in the Actions folder. As an example, Products can be managed using the following requests:

/**
 * List products.
 * Returns a paginated list of products.
 *
 * @param  int|null   $page_size  The maximum number of items to be returned in the response.
 * @param  int|null   $after      The lower limit for the version numbers to be included in the response.
 * @param  int|null   $before     The upper limit for the version numbers to be included in the response.
 * @param  bool|null  $deleted    Indicates whether deleted items should be included in the response.
 *
 * @return \SimpleSquid\Vend\Resources\TwoDotZero\ProductCollection
 */
$products = $vend->product->get($page_size, $after, $before, $deleted);

/**
 * Get a single product.
 * Returns a single product object with a given ID.
 *
 * @param  string  $id  Valid product ID.
 *
 * @return \SimpleSquid\Vend\Resources\TwoDotZero\Product
 */
$product = $vend->product->find($id);
