"The request is missing a valid API key."
Am making a web application that one can read books through the site. I want to use google drive to store my PDF files for the textbooks, and in my application the Drive should serve the pdfs on my site when one want to read a book, I am using drive API, but I keep on getting the ("The request is missing a valid API key.") error, am using Django. when I check the logs for my local server it is working([31/Dec/2024 13:17:54] "GET /books/9/link/ HTTP/1.1" 200 96), but on the browser the pdf is not served what should I do?
