+# PyPI API
+
+This is the API documentation for [PyPI Packages](../../user/packages/pypi_repository/index.md).
+
+WARNING:
+This API is used by the [PyPI package manager client](https://pypi.apache.org/)
+and is generally not meant for manual consumption.
+
+For instructions on how to upload and install PyPI packages from the GitLab
+package registry, see the [PyPI package registry documentation](../../user/packages/pypi_repository/index.md).
+
+NOTE:
+These endpoints do not adhere to the standard API authentication methods.
+See the [PyPI package registry documentation](../../user/packages/pypi_repository/index.md)
+for details on which headers and token types are supported.
+
+## Download a package file
+
+> Introduced in GitLab 12.10.
+
+Download a PyPI package file. The [simple API](#simple-api-entry-point)
+normally supplies this URL.

+| `sha256`          | string | yes | PyPI package file sha256 check sum. |
+| `file_identifier` | string | yes | The PyPI package file name. |
+
+```shell
