+# Project import API
+
+[Introduced][ce-41899] in GitLab 10.6
+
+[See also the project import/export documentation](../user/project/settings/import_export.md)
+
+## Import a file
+
+```http
+POST /projects/import
+```
+
+| Attribute | Type           | Required | Description                              |
+| --------- | -------------- | -------- | ---------------------------------------- |
+| `namespace` | integer/string | no | The ID or path of the namespace that the project will be imported to. Defaults to the current user's namespace |
+| `file` | string | yes | The file to be uploaded |
+| `path` | string | yes | Name and path for new project |
+
+To upload a file from your filesystem, use the `--form` argument. This causes
+cURL to post data using the header `Content-Type: multipart/form-data`.
+The `file=` parameter must point to a file on your filesystem and be preceded
+by `@`. For example:
+
+```console
+curl --request POST --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" --form "path=api-project" --form "file=@/path/to/file" https://gitlab.example.com/api/v4/projects/import
+```
+
+```json
+{
+  "id": 1,
+  "description": null,
+  "name": "api-project",
+  "name_with_namespace": "Administrator / api-project",
+  "path": "api-project",
+  "path_with_namespace": "root/api-project",
+  "created_at": "2018-02-13T09:05:58.023Z",
+  "import_status": "scheduled"
+}
+```
+
+## Import status
+
+Get the status of an import.
+
+```http
+GET /projects/:id/import
+```
+
+| Attribute | Type           | Required | Description                              |
+| --------- | -------------- | -------- | ---------------------------------------- |
+| `id`      | integer/string | yes      | The ID or [URL-encoded path of the project](README.md#namespaced-path-encoding) owned by the authenticated user |
+
+```console
+curl --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v4/projects/1/import
+```
+
+Status can be one of `none`, `scheduled`, `failed`, `started`, or `finished`.
+
+If the status is `failed`, it will include the import error message under `import_error`.
+
+```json
+{
+  "id": 1,
+  "description": "Itaque perspiciatis minima aspernatur corporis consequatur.",
+  "name": "Gitlab Test",
+  "name_with_namespace": "Gitlab Org / Gitlab Test",
