Create a Prestashop module for dropshipping

Details Our customer have a Prestashop e-commerce. His supplier use a dropshipping webservice with a REST API for dropshping. The customer want to plug his prestashop to the supplier webservice. The goal: Automate Internet orders via the dropshipping --------------------------------------------------------------------- The system should independently manage the import of the categories of products (with variations), their update, inventory management. Orders should be sent to the supplier after confirmation of payment. Order tracking (status, package tracking, etc.) should be updated in Prestashop with the information provided by the supplier, including for returns. TECHNICAL LIMITATIONS ------------------------------- Data synchronization must be through CRON tasks (Linux hosting). The tables in the database must not be emptied (add or update) the development shall not alter the native files of PrestaShop. It is recommended to use overrides if class changes (AdminImport ...) or controllers are required. REST API - Web Service ------------------------------------------------------------------ (See attachments: documentation, examples of PHP scripts, fluxs) WebServices flows and stock generate CSV files encoded in UTF8. Other WebServices generate a JSON response. # PRODUCTS Returns the flow of the stock trader of products -> CSV, update every day (5:30) Return the stock available for traders products -> CSV, update every hour # CARRIERS List all shipping brackets -> To update every day # ORDERS Creates the order and reserve the products stocks -> Validation of a command returns the status of an order -> Hourly Returns tracking (tracking number) of orders -> Hourly Returns orders for which a return has been processed -> Hourly Fluxs ------ The files in this folder are the returns associated with the URL of documentation. They are provided for information to enable a better assessment of the application.
