PHP application for checking new auctions

This should be small script executed every x minutes using CRON or queue that will check new products (within defined criteria posted) to on eBay using eBay's API. No interface required. Notification should be sent to slack channel or just stored in the db. Criteria of product: - country - search string - category - condition This could be defined as an array for example: <?php $filters = [ [ 'name' => 'product 1', 'searchString' => 'iPhone', 'categoryId' => 1221, 'country' => 'UK' // country id will be enough as well ], [ 'name' => 'product 1', 'searchString' => 'MacBook', 'categoryId' => 1221, 'country' => 'UK' // country id will be enough as well ], ] TECHNOLOGY - PHP + preferably laravel - MySQL if required for storing products or last product id This should be very simple script possibly below 500 lines of code for someone who knows what they are doing. Web based example is here: [login to view URL] not sure if it's working as the code doesn't look very clean. Application must be demonstrated working.
