Nvidia API

The Nvidia driver download page uses an API in the background to supply the correct drivers for the data entered.

The base API url used for EnvyUpdate is https://www.nvidia.com/Download/processDriver.aspx. It works using regular HTTP GET requests.

Accepted arguments which were found so far are:

API name	required?	default value	explanation	example
psid	yes		Product Series ID	psid=101 for GeForce 10 Series
pfid	yes		Product ID	psid=101&pfid=845 for GeForce GTX 1080 Ti
osid	yes		Operating System ID	osid=57 for Windows 10 64bit
lid	no	1	Language ID, defaults to English (US)	lid=1 for English (US).
dtcid	no	0	Switch to use DCH drivers or not. Defaults to non-DCH.	dtcid=1 for DCH drivers
dtid	no	1	Game Ready Driver or Studio Driver	dtid=1 for GRD, dtid=18 for SD

The API uses multiple different IDs to work, which are mostly arbitrary. These can be found using a different API URL.

• List all GPUs with their psid (the value in ParentID) and theit pfid (the value in Value): https://www.nvidia.com/Download/API/lookupValueSearch.aspx?TypeID=3
• List all operating systems and their ID (Value): https://www.nvidia.com/Download/API/lookupValueSearch.aspx?TypeID=4
• List all languages and their ID (Value): https://www.nvidia.com/Download/API/lookupValueSearch.aspx?TypeID=5

A complete request URL with all parameters would be in this form:

https://www.nvidia.com/Download/processDriver.aspx?psid=<ProductSeries>&pfid=<ProductType>&osid=<OperatingSystem>&lid=<Language>&dtcid=<0 or 1>&dtid=<1 or 18>

An example URL for the most recent driver for the GeForce 1080 Ti for Windows 10 x64 using UK English and DCH would be:

https://www.nvidia.com/Download/processDriver.aspx?psid=101&pfid=845&osid=57&lid=2&dtcid=1&dtid=1

Keep in mind that this API returns a URL to the download page of the most recent driver, NOT a direct download link!

The returned value may be a full URL (https://nvidia.com/), a protocol-agnostic URL (://nvidia.com/) or just a relative link to the driver page ((/DownloadDriver.aspx/).
