+# Composer API
+
+This is the API documentation for [Composer Packages](../../user/packages/composer_repository/index.md).
+
+WARNING:
+This API is used by the [Composer package manager client](https://getcomposer.org/)
+and is generally not meant for manual consumption.
+
+For instructions on how to upload and install Composer packages from the GitLab
+package registry, see the [Composer package registry documentation](../../user/packages/composer_repository/index.md).
+
+NOTE:
+These endpoints do not adhere to the standard API authentication methods.
+See the [Composer package registry documentation](../../user/packages/composer_repository/index.md)
+for details on which headers and token types are supported.
+
+## Base repository request
+
+Returns the repository URL templates for requesting individual packages:
+
+```plaintext
+GET group/:id/-/packages/composer/packages
+```
+
+| Attribute | Type   | Required | Description |
+| --------- | ------ | -------- | ----------- |
+| `id`      | string | yes      | The ID or full path of the group. |
+
+```shell
+curl --user <username>:<personal_access_token> "https://gitlab.example.com/api/v4/group/1/-/packages/composer/packages"
+```
+
+Example response:
+
+```json
+{
+  "packages": [],
+  "metadata-url": "/api/v4/group/1/-/packages/composer/p2/%package%.json",
+  "provider-includes": {
+    "p/%hash%.json": {
+      "sha256": "082df4a5035f8725a12i4a3d2da5e6aaa966d06843d0a5c6d499313810427bd6"
+    }
+  },
+  "providers-url": "/api/v4/group/1/-/packages/composer/%package%$%hash%.json"
+}
+```
+
+This endpoint is used by Composer V1 and V2. To see the V2-specific response, include the Composer
+`User-Agent` header. Using Composer V2 is recommended over V1.
+
+```shell
+curl --user <username>:<personal_access_token> \

+     "https://gitlab.example.com/api/v4/group/1/-/packages/composer/packages"
+```
+
+Example response:
+
+```json
+{
+  "packages": [],
+  "metadata-url": "/api/v4/group/1/-/packages/composer/p2/%package%.json"
+}
+```
+
+## V1 packages list
+
+Given the V1 provider sha, returns a list of packages within the repository. Using Composer V2 is
+recommended over V1.
+
+```plaintext

+    }
+  }
+}
+```
+
+## V1 Package Metadata
+
+Returns the list of versions and metadata for a given package. Using Composer V2 is recommended over

+# Ruby gems API
+
+This is the API documentation for [Ruby gems](../../user/packages/rubygems_registry/index.md).
+
+WARNING:
+This API is used by the [Ruby gems and Bundler package manager clients](https://maven.apache.org/)
+and is generally not meant for manual consumption. This API is under development and is not ready
+for production use due to limited functionality.
+
+For instructions on how to upload and install gems from the GitLab
+package registry, see the [Ruby gems registry documentation](../../user/packages/rubygems_registry/index.md).
+
+NOTE:
+These endpoints do not adhere to the standard API authentication methods.
+See the [Ruby gems registry documentation](../../user/packages/rubygems_registry/index.md)
+for details on which headers and token types are supported.
+
+## Enable the Ruby gems API
+
+The Ruby gems API for GitLab is behind a feature flag that is disabled by default. GitLab
+administrators with access to the GitLab Rails console can enable this API for your instance.
+
+To enable it:
+
+```ruby
+Feature.enable(:rubygem_packages)
+```
+
+To disable it:
+
+```ruby
+Feature.disable(:rubygem_packages)
+```
+
+To enable or disable it for specific projects:
+
+```ruby
+Feature.enable(:rubygem_packages, Project.find(1))
+Feature.disable(:rubygem_packages, Project.find(2))
+```
+
+## Download a gem file
+
+> Introduced in GitLab 13.10.
+
+Download a gem:
+
+```plaintext
+GET projects/:id/packages/rubygems/gems/:file_name
+```
+
+| Attribute    | Type   | Required | Description |
+| ------------ | ------ | -------- | ----------- |
+| `id`         | string | yes      | The ID or full path of the project. |
+| `file_name`  | string | yes      | The name of the `.gem` file. |
+
+```shell
+curl --header "Authorization:<personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/rubygems/gems/my_gem-1.0.0.gem"
+```
+
+Write the output to file:
+
+```shell
+curl --header "Authorization:<personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/rubygems/gems/my_gem-1.0.0.gem" >> my_gem-1.0.0.gem
+```
+
+This writes the downloaded file to `my_gem-1.0.0.gem` in the current directory.
+
+## Fetch a list of dependencies
+
+> Introduced in GitLab 13.10.
+
+Fetch a list of dependencies for a list of gems:
+
+```plaintext
+GET projects/:id/packages/rubygems/api/v1/dependencies
+```
+
+| Attribute | Type   | Required | Description |
+| --------- | ------ | -------- | ----------- |
+| `id`      | string | yes      | The ID or full path of the project. |
+| `gems`    | string | no       | Comma-separated list of gems to fetch dependencies for. |
+
+```shell
+curl --header "Authorization:<personal_access_token>" "https://gitlab.example.com/api/v4/projects/1/packages/rubygems/api/v1/dependencies?gems=my_gem,foo"
+```
+
+This endpoint returns a marshalled array of hashes for all versions of the requested gems. Since the
+response is marshalled, you can store it in a file. If Ruby is installed, you can use the following
+Ruby command to read the response. For this to work, you must
+[set your credentials in `~/.gem/credentials`](../../user/packages/rubygems_registry/index.md#authenticate-with-a-personal-access-token-or-deploy-token):
+
+```shell
+$ ruby -ropen-uri -rpp -e \
+  'pp Marshal.load(open("https://gitlab.example.com/api/v4/projects/1/packages/rubygems/api/v1/dependencies?gems=my_gem,rails,foo"))'
+
+[{:name=>"my_gem", :number=>"0.0.1", :platform=>"ruby", :dependencies=>[]},
+ {:name=>"my_gem",
+  :number=>"0.0.3",
+  :platform=>"ruby",
+  :dependencies=>
+   [["dependency_1", "~> 1.2.3"],
+    ["dependency_2", "= 3.0.0"],
+    ["dependency_3", ">= 1.0.0"],
+    ["dependency_4", ">= 0"]]},
+ {:name=>"my_gem",
+  :number=>"0.0.2",
+  :platform=>"ruby",
+  :dependencies=>
+   [["dependency_1", "~> 1.2.3"],
+    ["dependency_2", "= 3.0.0"],
+    ["dependency_3", ">= 1.0.0"],
+    ["dependency_4", ">= 0"]]},
+ {:name=>"foo",
+  :number=>"0.0.2",
+  :platform=>"ruby",
+  :dependencies=>
+    ["dependency_2", "= 3.0.0"],
+    ["dependency_4", ">= 0"]]}]
+```
+
+This writes the downloaded file to `mypkg-1.0-SNAPSHOT.jar` in the current directory.
+
+## Upload a gem
+
+> Introduced in GitLab 13.11.
+
+Upload a gem:
+
+```plaintext
+POST projects/:id/packages/rubygems/api/v1/gems
+```
+
+| Attribute | Type   | Required | Description |
+| --------- | ------ | -------- | ----------- |
+| `id`      | string | yes      | The ID or full path of the project. |
+
+```shell
+curl --request POST \
+     --upload-file path/to/my_gem_file.gem \
+     --header "Authorization:<personal_access_token>" \
+     "https://gitlab.example.com/api/v4/projects/1/packages/rubygems/api/v1/gems"
