NuGet API (FREE ALL)

This is the API documentation for NuGet Packages.

WARNING: This API is used by the NuGet package manager client and is generally not meant for manual consumption.

For instructions on how to upload and install NuGet packages from the GitLab package registry, see the NuGet package registry documentation.

NOTE: These endpoints do not adhere to the standard API authentication methods. See the NuGet package registry documentation for details on which headers and token types are supported. Undocumented authentication methods might be removed in the future.

package_name string yes The name of the package. 
curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/projects/1/packages/nuget/download/MyNuGetPkg/index"

Example response:

{
  "versions": [
    "1.3.0.17"
  ]
}

Download a package file

Introduced in GitLab 12.8.

Download a NuGet package file. The metadata service provides this URL.
