Retrieves the download location for a completed Document Generator output.
By default, the API responds with an HTTP redirect to the output content URL. Set redirect=false to return the download URL as a JSON response body instead.
You can also get a specific type of generated output for Google URLs, such as Google Slides or Goggle Docs.
This endpoint also supports the "pptx", "docx", "pdf", "gslides", "gdoc" keywords as special aliases which enables users to use this endpoint without getting the generated outputId beforehand.
