Absolutely amazing. I remember working in PHP and how miserable I was but everything did what you expected it to do when it came to requests. This was a surprising gotcha for a language as mature and user-friendly as Python. People write code and people forget I guess. SolutionIn the end, I decided to use a loop to populate the parameters: extra_fields = [ "PictureURLLarge", "PictureURLSuperSize", "GalleryInfo", "UnitPriceInfo"] Using the RESPONSE-DATA-FORMAT=JSON&REST-PAYLOAD=true&paginationInput.entriesPerPage=100&paginationInput.pageNumber=1&outputSelector%5B0%5D=PictureURLLarge&outputSelector%5B1%5D=PictureURLSuperSize&outputSelector%5B2%5D=GalleryInfo&outputSelector%5B3%5D=UnitPriceInfo The whole URL: https://svcs.ebay.com/services/search/FindingService/v1?RESPONSE-DATA-FORMAT=JSON&REST-PAYLOAD=true&paginationInput.entriesPerPage=100&paginationInput.pageNumber=1&outputSelector%5B0%5D=PictureURLLarge&outputSelector%5B1%5D=PictureURLSuperSize&outputSelector%5B2%5D=GalleryInfo&outputSelector%5B3%5D=UnitPriceInfo And it works!
