# Internal API **(FREE)**

The internal API is used by different GitLab components, it can not be
used by other consumers. This documentation is intended for people
working on the GitLab codebase.

This documentation does not yet include the internal API used by
GitLab Pages.

## Adding new endpoints

API endpoints should be externally accessible by default, with proper authentication and authorization.
Before adding a new internal endpoint, consider if the API would potentially be
useful to the wider GitLab community and can be made externally accessible.

One reason we might favor internal API endpoints sometimes is when using such an endpoint requires
internal data that external actors can not have. For example, in the internal Pages API we might use
a secret token that identifies a request as internal or sign a request with a public key that is
not available to a wider community.

Another reason to separate something into an internal API is when request to such API endpoint
should never go through an edge (public) load balancer. This way we can configure different rate
limiting rules and policies around how the endpoint is being accessed, because we know that only
internal requests can be made to that endpoint going through an internal load balancer.

## Authentication

These methods are all authenticated using a shared secret. This secret
is stored in a file at the path configured in `config/gitlab.yml` by
default this is in the root of the rails app named
`.gitlab_shell_secret`

To authenticate using that token, clients read the contents of that
file, and include the token Base64 encoded in a `secret_token` parameter
or in the `Gitlab-Shared-Secret` header.

NOTE:
The internal API used by GitLab Pages, and GitLab agent server (`kas`) uses JSON Web Token (JWT)
authentication, which is different from GitLab Shell.

## Git Authentication

This is called by [Gitaly](https://gitlab.com/gitlab-org/gitaly) and
[GitLab Shell](https://gitlab.com/gitlab-org/gitlab-shell) to check access to a
repository.

- **When called from GitLab Shell**: No changes are passed, and the internal
  API replies with the information needed to pass the request on to Gitaly.
- **When called from Gitaly in a `pre-receive` hook**: The changes are passed
  and validated to determine if the push is allowed.

Calls are limited to 50 seconds each.

This endpoint is covered in more detail on [its own page](internal_api_allowed.md), due to the scope of what it covers.

## GitLab agent endpoints

> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/41045) in GitLab 13.4.
> - This feature is not deployed on GitLab.com
> - It's not recommended for production use.

The following endpoints are used by the GitLab agent server (`kas`)
for various purposes.

These endpoints are all authenticated using JWT. The JWT secret is stored in a file
specified in `config/gitlab.yml`. By default, the location is in the root of the
GitLab Rails app in a file called `.gitlab_kas_secret`.

### GitLab agent information

Called from GitLab agent server (`kas`) to retrieve agent
information for the given agent token. This returns the Gitaly connection
information for the agent's project in order for `kas` to fetch and update
the agent's configuration.

```plaintext
GET /internal/kubernetes/agent_info
```

Example Request:

```shell
curl --request GET --header "Gitlab-Kas-Api-Request: <JWT token>" \

```

### GitLab agent project information

Called from GitLab agent server (`kas`) to retrieve project
information for the given agent token. This returns the Gitaly
connection for the requested project. GitLab `kas` uses this to configure
the agent to fetch Kubernetes resources from the project repository to
sync.

Only public projects are supported. For private projects, the ability for the
agent to be authorized is [not yet implemented](https://gitlab.com/gitlab-org/gitlab/-/issues/220912).

| Attribute | Type   | Required | Description |
|:----------|:-------|:---------|:------------|
| `id` | integer/string | yes | The ID or [URL-encoded path of the project](../../api/index.md#namespaced-path-encoding) |

```plaintext
GET /internal/kubernetes/project_info
```

Example Request:

```shell
curl --request GET --header "Gitlab-Kas-Api-Request: <JWT token>" \
     --header "Authorization: Bearer <agent token>" "http://localhost:3000/api/v4/internal/kubernetes/project_info?id=7"
```

Called from GitLab agent server (`kas`) to increase the usage
metric counters.

| Attribute | Type   | Required | Description |
|:----------|:-------|:---------|:------------|

```plaintext
POST /internal/kubernetes/usage_metrics
```

Example Request:
