Internal API

The internal API is used by different GitLab components, it cannot 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.

For information on the GitLab Subscriptions internal API, see the dedicated page.

Add 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 benefit 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 cannot 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.
Use the file contents to generate a JSON Web Token (JWT).
Pass the JWT in the Gitlab-Shell-Api-Request header.

Git Authentication

Called by Gitaly and 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, due to the scope of what it covers.

The group SCIM API partially implements the RFC7644 protocol. This API provides the /groups/:group_path/Users and /groups/:group_path/Users/:id endpoints. The base URL is <http|https>://<GitLab host>/api/scim/v2. Because this API is for system use for SCIM provider integration, it is subject to change without notice.

To use this API, enable Group SSO for the group. This API is only in use where SCIM for Group SSO is enabled. It's a prerequisite to the creation of SCIM identities.

This group SCIM API:

Is for system use for SCIM provider integration.
Implements the RFC7644 protocol.
Gets a list of SCIM provisioned users for the group.
Creates, deletes and updates SCIM provisioned users for the group.

The instance SCIM API does the same for instances.

This group SCIM API is different to the SCIM API. The SCIM API:

Is not an internal API.
Does not implement the RFC7644 protocol.
Gets, checks, updates, and deletes SCIM identities in groups.

NOTE: This API does not require the Gitlab-Shell-Api-Request header.

Get a list of SCIM provisioned users

This endpoint is used as part of the SCIM syncing mechanism. It returns a list of users depending on the filter used.

GET /api/scim/v2/groups/:group_path/Users

Parameters:

Attribute	Type	Required	Description
`filter`	string	no	A filter expression.
`group_path`	string	yes	Full path to the group.
`startIndex`	integer	no	The 1-based index indicating where to start returning results from. A value of less than one is interpreted as 1.
`count`	integer	no	Desired maximum number of query results.

NOTE: Pagination follows the SCIM spec rather than GitLab pagination as used elsewhere. If records change between requests it is possible for a page to either be missing records that have moved to a different page or repeat records from a previous request.

Example request filtering on a specific identifier:

curl "https://gitlab.example.com/api/scim/v2/groups/test_group/Users?filter=id%20eq%20%220b1d561c-21ff-4092-beab-8154b17f82f2%22" \
