WARNING: This API is used by the [NuGet package manager client](https://www.nuget.org/) 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](../../user/packages/nuget_repository/index.md). NOTE: These endpoints do not adhere to the standard API authentication methods. See the [NuGet package registry documentation](../../user/packages/nuget_repository/index.md) for details on which headers and token types are supported. Undocumented authentication methods might be removed in the future. ## Package index > Introduced in GitLab 12.8. Returns the index for a given package, which includes a list of available versions: ```plaintext 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. | ```shell curl --user : "https://gitlab.example.com/api/v4/projects/1/packages/nuget/download/MyNuGetPkg/index" ``` Example response: ```json { "versions": [ "1.3.0.17" ] } ``` ## Download a package file > Introduced in GitLab 12.8. Download a NuGet package file. The [metadata service](#metadata-service) provides this URL. ```plaintext 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. | | `package_filename`| string | yes | The name of the file. | ```shell curl --user : "https://gitlab.example.com/api/v4/projects/1/packages/nuget/download/MyNuGetPkg/1.3.0.17/mynugetpkg.1.3.0.17.nupkg" ``` Write the output to a file: ```shell curl --user : "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. ## Upload a package file > Introduced in GitLab 12.8. Upload a NuGet package file: ```plaintext PUT projects/:id/packages/nuget ``` | 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. | | `package_filename`| string | yes | The name of the file. | ```shell curl --request PUT \ --form 'package=@path/to/mynugetpkg.1.3.0.17.nupkg' \ --user : \ "https://gitlab.example.com/api/v4/projects/1/packages/nuget/" ``` ## Upload a symbol package file > Introduced in GitLab 12.8.

The examples in this document all use the project-level prefix. ### Group-level ```plaintext /groups/:id/-/packages/nuget` ``` | Attribute | Type | Required | Description | | --------- | ------ | -------- | ----------- | | `id` | string | yes | The group ID or full group path. | ### Project-level ```plaintext /projects/:id/packages/nuget` ``` | Attribute | Type | Required | Description | | --------- | ------ | -------- | ----------- | | `id` | string | yes | The project ID or full project path. | ## Service Index > Introduced in GitLab 12.6.
