create a little webscript to generate csv file

Read this project good! Your bid can not go up!! Do only bid if you are sure you can make this, and for the money you bid, so when I start chatting, I dont want to see raise of the price before we even started! My supplier just launched a API portal to have up to date product information for my webshops I have myself no knowledge about scripting, so I need a developper who can make a webpage, who does in the background the authentication, where I can select what I want. They have created the option to get the product details per segment: Query Parameters Parameter Status Description segment required Segment ID (1 = Bikes, 2 = Bike Parts, 3 = Toys, 4 = Sportclubs, 5 = Sport and Casual, 6 = Automotive, 7 = Eyewear, 8 = Books) So, the page I want to created, let me select first for which segment I want the products, like 1 and it generates then the file with all the product information about all their bikes : Example response (200): { "data": [ { "id": 222, "name_en": "164R-09W Winx 16 Inch 26 cm Girls Caliper Pink", "name_nl": "164R-09W Winx 16 Inch 26 cm Meisjes Knijprem Roze", "name_de": "164R-09W Winx 16 Zoll 26 cm Mädchen Felgenbremse Rosa", "brand": "Dino", "ean": "8006817164265", "price": 81.78, "consumer_price": 131.95, "categories": [ { "id": 15, "name_en": "Childeren Bikes Girls", "name_nl": "Meisjesfietsen", "name_de": "Kinderfahrräder Mädchen" }, { "id": 9289, "name_en": "Childeren Bikes Girls", "name_nl": "Meisjesfietsen", "name_de": "Kinderfahrräder Mädchen" } ], "image_1": "https:\/\/[login to view URL]\/producten\/original\/[login to view URL]", "image_2": null, "shipping_size": "M", "stock": 11 } ], "links": { "first": "https:\/\/[login to view URL]\/api\/twm\/products?page=1", "last": "https:\/\/[login to view URL]\/api\/twm\/products?page=334", "prev": null, "next": "https:\/\/[login to view URL]\/api\/twm\/products?page=2" }, "meta": { "current_page": 1, "from": 1, "last_page": 334, "path": "https:\/\/[login to view URL]\/api\/twm\/products", "per_page": 15, "to": 15, "total": 5008 } } and so on, and generates a csv file, so I can still do some things with it, before I upload the content to my webshop.
