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 inParentID) and theitpfid(the value inValue): 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/).
