The PHP class will be called "FANCourierShipmentExpedition" and it will represent a module in an existing software system - a software module. The existing software system is used to manage a warehouse. The "FANCourierShipmentExpedition" class should contain data structures (which are described in an attached document) and methods responsible for communication with an application-programming interface (API) of a courier company. The methods should perform the following functionalities: 1. send information about shipments which await expedition in our warehouse to the courier company (the number of shipments, their weight, their target destination, ...) 2. retrieve information from courier company API and create a PDF document from this information, which will subsequently be printed on our printer(s) and stuck to the shipment 3. retrieve tracking information about the shipments and store this information in our system.
