Why can’t I view the output anymore

The PDF.co generated URLs are temporary and are set to expire after an 1 hour by default for security reasons. You can increase the output link expiration up to 1440 mins in higher plans using the expiration parameter. We highly recommend that you store the PDF.co output in a permanent cloud storage such as Google Drive, Dropbox or similar services.
