NuGet API

DETAILS: Tier: Free, Premium, Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated

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 index

Returns the index for a given package, which includes a list of available versions:

GET projects/:id/packages/nuget/download/:package_name/index
Attribute Type Required Description
id string yes The ID or full path of the project.
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

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

GET projects/:id/packages/nuget/download/:package_name/:package_version/:package_filename
Attribute Type Required Description
id string yes The ID or full path of the project.
package_name string yes The name of the package.
package_version string yes The version of the package.

Write the output to a file:

curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/projects/1/packages/nuget/download/MyNuGetPkg/1.3.0.17/mynugetpkg.1.3.0.17.nupkg" > MyNuGetPkg.1.3.0.17.nupkg

This writes the downloaded file to MyNuGetPkg.1.3.0.17.nupkg in the current directory.

     "https://gitlab.example.com/api/v4/projects/1/packages/nuget/symbolpackage"

Route prefix

For the remaining routes, there are two sets of identical routes that each make requests in different scopes:

  • Use the group-level prefix to make requests in a group's scope.
  • Use the project-level prefix to make requests in a single project's scope.

The examples in this document all use the project-level prefix.

Group-level

/groups/:id/-/packages/nuget

id string yes The group ID or full group path.

Project-level

/projects/:id/packages/nuget
Attribute Type Required Description
