# GitLab API
|
|
|
|
Automate GitLab via a simple and powerful API.
|
|
|
|
The main GitLab API is a [REST](https://en.wikipedia.org/wiki/Representational_state_transfer) API. Therefore, documentation in this section assumes knowledge of REST concepts.
|
|
|
|
## API resources
|
|
|
|
Available API resources can be grouped in the following contexts:
|
|
|
|
- [Projects](#project-resources).
|
|
- [Groups](#group-resources).
|
|
- [Standalone](#standalone-resources).
|
|
|
|
See also:
|
|
|
|
- [V3 to V4](v3_to_v4.md).
|
|
- Adding [deploy keys for multiple projects](deploy_key_multiple_projects.md).
|
|
|
|
### Project resources
|
|
|
|
The following API resources are available in the project context:
|
|

|
|
|
## SCIM **(SILVER ONLY)**
|
|
|
|
[GitLab.com Silver and above](https://about.gitlab.com/pricing/) provides an [SCIM API](scim.md) that implements [the RFC7644 protocol](https://tools.ietf.org/html/rfc7644) and provides
|
|
the `/Users` endpoint. The base URL is: `/api/scim/v2/groups/:group_path/Users/`.
|
|
|
|
## Road to GraphQL
|
|
|
|
[GraphQL](graphql/index.md) is available in GitLab, which will
|
|
allow deprecation of controller-specific endpoints.
|
|
|
|
GraphQL has a number of benefits:
|
|
|
|
1. We avoid having to maintain two different APIs.
|
|
1. Callers of the API can request only what they need.
|
|
1. It is versioned by default.
|
|
|
|
It will co-exist with the current v4 REST API. If we have a v5 API, this should
|
|
be a compatibility layer on top of GraphQL.
|
|
|
|
Although there were some patenting and licensing concerns with GraphQL, these
|
|
have been resolved to our satisfaction by the relicensing of the reference
|
|
implementations under MIT, and the use of the OWF license for the GraphQL
|
|
specification.
|
|
|
|
## Compatibility guidelines
|
|
|
|
The HTTP API is versioned using a single number, the current one being 4. This
|
|
number symbolizes the same as the major version number as described by
|
|
[SemVer](https://semver.org/). This mean that backward incompatible changes
|
|
will require this version number to change. However, the minor version is
|
|
not explicit. This allows for a stable API endpoint, but also means new
|
|
features can be added to the API in the same version number.
|
|
|
|
New features and bug fixes are released in tandem with a new GitLab, and apart
|
|
from incidental patch and security releases, are released on the 22nd of each
|
|
month. Backward incompatible changes (e.g. endpoints removal, parameters
|
|
removal etc.), as well as removal of entire API versions are done in tandem
|
|
with a major point release of GitLab itself. All deprecations and changes
|
|
between two versions should be listed in the documentation. For the changes
|
|
between v3 and v4; please read the [v3 to v4 documentation](v3_to_v4.md)
|
|
|
|
### Current status
|
|
|
|
Currently only API version v4 is available. Version v3 was removed in
|
|
[GitLab 11.0](https://gitlab.com/gitlab-org/gitlab-ce/issues/36819).
|
|
|
|
## Basic usage
|
|
|
|
API requests should be prefixed with `api` and the API version. The API version
|
|
is defined in [`lib/api.rb`][lib-api-url]. For example, the root of the v4 API
|
|
is at `/api/v4`.
|
|
|
|
Example of a valid API request using cURL:
|
|
|
|
```shell
|
|
curl "https://gitlab.example.com/api/v4/projects"
|
|
```
|
|
|
|
The API uses JSON to serialize data. You don't need to specify `.json` at the
|
|
end of an API URL.
|
|
|
|
## Authentication
|
|
|
|
Most API requests require authentication, or will only return public data when
|
|
authentication is not provided. For
|
|
those cases where it is not required, this will be mentioned in the documentation
|
|
for each individual endpoint. For example, the [`/projects/:id` endpoint](projects.md).
|
|
|
|
There are three ways to authenticate with the GitLab API:
|
|
|
|
1. [OAuth2 tokens](#oauth2-tokens)
|
|
1. [Personal access tokens](#personal-access-tokens)
|
|
1. [Session cookie](#session-cookie)
|
|
|
|
For admins who want to authenticate with the API as a specific user, or who want to build applications or scripts that do so, two options are available:
|
|
|
|
1. [Impersonation tokens](#impersonation-tokens)
|
|
1. [Sudo](#sudo)
|
|
|
|
If authentication information is invalid or omitted, an error message will be
|
|
returned with status code `401`:
|
|
|
|
```json
|
|
{
|
|
"message": "401 Unauthorized"
|
|
}
|
|
```
|
|
|
|
### OAuth2 tokens
|
|
|
|
You can use an [OAuth2 token](oauth2.md) to authenticate with the API by passing it in either the
|
|
`access_token` parameter or the `Authorization` header.
|
|
|
|
Example of using the OAuth2 token in a parameter:
|
|
|
|
```shell
|
|
curl https://gitlab.example.com/api/v4/projects?access_token=OAUTH-TOKEN
|
|
```
|
|
|
|
Example of using the OAuth2 token in a header:
|
|
|
|
```shell
|
|
curl --header "Authorization: Bearer OAUTH-TOKEN" https://gitlab.example.com/api/v4/projects
|
|
```
|
|
|
|
Read more about [GitLab as an OAuth2 provider](oauth2.md).
|
|
|
|
### Personal access tokens
|
|
|
|
You can use a [personal access token][pat] to authenticate with the API by passing it in either the
|
|
`private_token` parameter or the `Private-Token` header.
|
|
|
|
Example of using the personal access token in a parameter:
|
|
|
|
```shell
|
|
curl https://gitlab.example.com/api/v4/projects?private_token=<your_access_token>
|
|
```
|
|
|
|
Example of using the personal access token in a header:
|
|
|
|
```shell
|
|
curl --header "Private-Token: <your_access_token>" https://gitlab.example.com/api/v4/projects
|
|
```
|
|
|
|
You can also use personal access tokens with OAuth-compliant headers:
|
|
|
|
```shell
|
|
curl --header "Authorization: Bearer <your_access_token>" https://gitlab.example.com/api/v4/projects
|
|
```
|
|
|
|
Read more about [personal access tokens][pat].
|
|
|
|
### Session cookie
|
|
|
|
When signing in to the main GitLab application, a `_gitlab_session` cookie is
|
|
set. The API will use this cookie for authentication if it is present, but using
|
|
the API to generate a new session cookie is currently not supported.
|
|
|
|
The primary user of this authentication method is the web frontend of GitLab itself,
|
|
which can use the API as the authenticated user to get a list of their projects,
|
|
for example, without needing to explicitly pass an access token.
|
|
|
|
### Impersonation tokens
|
|
|
|
> [Introduced][ce-9099] in GitLab 9.0. Needs admin permissions.
|
|
|
|
Impersonation tokens are a type of [personal access token][pat]
|
|
that can only be created by an admin for a specific user. They are a great fit
|
|
if you want to build applications or scripts that authenticate with the API as a specific user.
|
|
|
|
They are an alternative to directly using the user's password or one of their
|
|
personal access tokens, and to using the [Sudo](#sudo) feature, since the user's (or admin's, in the case of Sudo)
|
|
password/token may not be known or may change over time.
|
|
|
|
For more information, refer to the
|
|
[users API](users.md#create-an-impersonation-token) docs.
|
|
|
|
Impersonation tokens are used exactly like regular personal access tokens, and can be passed in either the
|
|
`private_token` parameter or the `Private-Token` header.
|
|
|
|
#### Disable impersonation
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/issues/40385) in GitLab
|
|
11.6.
|
|
|
|
By default, impersonation is enabled. To disable impersonation:
|
|
|
|
**For Omnibus installations**
|
|
|
|
1. Edit `/etc/gitlab/gitlab.rb`:
|
|
|
|
```ruby
|
|
gitlab_rails['impersonation_enabled'] = false
|
|
```
|
|
|
|
1. Save the file and [reconfigure](../administration/restart_gitlab.md#omnibus-gitlab-reconfigure)
|
|
GitLab for the changes to take effect.
|
|
|
|
To re-enable impersonation, remove this configuration and reconfigure GitLab.
|
|
|
|
**For installations from source**
|
|
|
|
1. Edit `config/gitlab.yml`:
|
|
|
|
```yaml
|
|
gitlab:
|
|
impersonation_enabled: false
|
|
```
|
|
|
|
1. Save the file and [restart](../administration/restart_gitlab.md#installations-from-source)
|
|
GitLab for the changes to take effect.
|
|
|
|
To re-enable impersonation, remove this configuration and restart GitLab.
|
|
|
|
### Sudo
|
|
|
|
NOTE: **Note:**
|
|
Only available to [administrators](../user/permissions.md).
|
|
|
|
All API requests support performing an API call as if you were another user,
|
|
provided you are authenticated as an administrator with an OAuth or Personal Access Token that has the `sudo` scope.
|
|
|
|
You need to pass the `sudo` parameter either via query string or a header with an ID/username of
|
|
the user you want to perform the operation as. If passed as a header, the
|
|
header name must be `Sudo`.
|
|
|
|
NOTE: **Note:**
|
|
Usernames are case insensitive.
|
|
|
|
If a non administrative access token is provided, an error message will
|
|
be returned with status code `403`:
|
|
|
|
```json
|
|
{
|
|
"message": "403 Forbidden - Must be admin to use sudo"
|
|
}
|
|
```
|
|
|
|
If an access token without the `sudo` scope is provided, an error message will
|
|
be returned with status code `403`:
|
|
|
|
```json
|
|
{
|
|
"error": "insufficient_scope",
|
|
"error_description": "The request requires higher privileges than provided by the access token.",
|
|
"scope": "sudo"
|
|
}
|
|
```
|
|
|
|
If the sudo user ID or username cannot be found, an error message will be
|
|
returned with status code `404`:
|
|
|
|
```json
|
|
{
|
|
"message": "404 User with ID or username '123' Not Found"
|
|
}
|
|
```
|
|
|
|
Example of a valid API call and a request using cURL with sudo request,
|
|
providing a username:
|
|
|
|
```
|
|
GET /projects?private_token=<your_access_token>&sudo=username
|
|
```
|
|
|
|
```shell
|
|
curl --header "Private-Token: <your_access_token>" --header "Sudo: username" "https://gitlab.example.com/api/v4/projects"
|
|
```
|
|
|
|
Example of a valid API call and a request using cURL with sudo request,
|
|
providing an ID:
|
|
|
|
```
|
|
GET /projects?private_token=<your_access_token>&sudo=23
|
|
```
|
|
|
|
```shell
|
|
curl --header "Private-Token: <your_access_token>" --header "Sudo: 23" "https://gitlab.example.com/api/v4/projects"
|
|
```
|
|
|
|
## Status codes
|
|
|
|
The API is designed to return different status codes according to context and
|
|
action. This way, if a request results in an error, the caller is able to get
|
|
insight into what went wrong.
|
|
|
|
The following table gives an overview of how the API functions generally behave.
|
|
|
|
| Request type | Description |
|
|
| ------------ | ----------- |
|
|
| `GET` | Access one or more resources and return the result as JSON. |
|
|
| `POST` | Return `201 Created` if the resource is successfully created and return the newly created resource as JSON. |
|
|
| `GET` / `PUT` | Return `200 OK` if the resource is accessed or modified successfully. The (modified) result is returned as JSON. |
|
|
| `DELETE` | Returns `204 No Content` if the resource was deleted successfully. |
|
|
|
|
The following table shows the possible return codes for API requests.
|
|
|
|
| Return values | Description |
|
|
| ------------- | ----------- |
|
|
| `200 OK` | The `GET`, `PUT` or `DELETE` request was successful, the resource(s) itself is returned as JSON. |
|
|
| `204 No Content` | The server has successfully fulfilled the request and that there is no additional content to send in the response payload body. |
|
|
| `201 Created` | The `POST` request was successful and the resource is returned as JSON. |
|
|
| `304 Not Modified` | Indicates that the resource has not been modified since the last request. |
|
|
| `400 Bad Request` | A required attribute of the API request is missing, e.g., the title of an issue is not given. |
|
|
| `401 Unauthorized` | The user is not authenticated, a valid [user token](#authentication) is necessary. |
|
|
| `403 Forbidden` | The request is not allowed, e.g., the user is not allowed to delete a project. |
|
|
| `404 Not Found` | A resource could not be accessed, e.g., an ID for a resource could not be found. |
|
|
| `405 Method Not Allowed` | The request is not supported. |
|
|
| `409 Conflict` | A conflicting resource already exists, e.g., creating a project with a name that already exists. |
|
|
| `412` | Indicates the request was denied. May happen if the `If-Unmodified-Since` header is provided when trying to delete a resource, which was modified in between. |
|
|
| `422 Unprocessable` | The entity could not be processed. |
|
|
| `500 Server Error` | While handling the request something went wrong server-side. |
|
|
|
|
## Pagination
|
|
|
|
Sometimes the returned result will span across many pages. When listing
|
|
resources you can pass the following parameters:
|
|
|
|
| Parameter | Description |
|
|
| --------- | ----------- |
|
|
| `page` | Page number (default: `1`) |
|
|
| `per_page`| Number of items to list per page (default: `20`, max: `100`) |
|
|
|
|
In the example below, we list 50 [namespaces](namespaces.md) per page.
|
|
|
|
```bash
|
|
curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/namespaces?per_page=50
|
|
```
|
|
|
|
### Pagination Link header
|
|
|
|
[Link headers](http://www.w3.org/wiki/LinkHeader) are sent back with each
|
|
response. They have `rel` set to prev/next/first/last and contain the relevant
|
|
URL. Please use these links instead of generating your own URLs.
|
|
|
|
In the cURL example below, we limit the output to 3 items per page (`per_page=3`)
|
|
and we request the second page (`page=2`) of [comments](notes.md) of the issue
|
|
with ID `8` which belongs to the project with ID `8`:
|
|
|
|
```bash
|
|
curl --head --header "PRIVATE-TOKEN: <your_access_token>" https://gitlab.example.com/api/v4/projects/8/issues/8/notes?per_page=3&page=2
|
|
```
|
|
|
|
The response will then be:
|
|
|
|
```
|
|
HTTP/1.1 200 OK
|
|
Cache-Control: no-cache
|
|
Content-Length: 1103
|
|
Content-Type: application/json

|
|

|
|
```
|
|
|
|
### Other pagination headers
|
|
|
|
Additional pagination headers are also sent back.
|
|
|
|
| Header | Description |
|
|
| ------ | ----------- |
|
|
| `X-Total` | The total number of items |
|
|
| `X-Total-Pages` | The total number of pages |
|
|
| `X-Per-Page` | The number of items per page |
|
|
| `X-Page` | The index of the current page (starting at 1) |
|
|
| `X-Next-Page` | The index of the next page |
|
|
| `X-Prev-Page` | The index of the previous page |
|
|
|
|
CAUTION: **Caution:**
|
|
For performance reasons since
|
|
[GitLab 11.8](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23931)
|
|
and **behind the `api_kaminari_count_with_limit`
|
|
[feature flag](../development/feature_flags.md)**, if the number of resources is
|
|
more than 10,000, the `X-Total` and `X-Total-Pages` headers as well as the
|
|
`rel="last"` `Link` are not present in the response headers.
|
|
|
|
## Namespaced path encoding
|
|
|
|
If using namespaced API calls, make sure that the `NAMESPACE/PROJECT_PATH` is
|
|
URL-encoded.
|
|
|
|
For example, `/` is represented by `%2F`:
|
|
|
|
```
|
|
GET /api/v4/projects/diaspora%2Fdiaspora
|
|
```
|
|
|
|
NOTE: **Note:**
|
|
A project's **path** is not necessarily the same as its **name**. A
|
|
project's path can found in the project's URL or in the project's settings
|
|
under **General > Advanced > Change path**.
|
|
|
|
## Branches and tags name encoding
|
|
|
|
If your branch or tag contains a `/`, make sure the branch/tag name is
|
|
URL-encoded.
|
|
|
|
For example, `/` is represented by `%2F`:
|
|
|
|
```
|
|
GET /api/v4/projects/1/branches/my%2Fbranch/commits
|
|
```
|
|
|
|
## Encoding API parameters of `array` and `hash` types
|
|
|
|
We can call the API with `array` and `hash` types parameters as shown below:
|
|
|
|
### `array`
|
|
|
|
`import_sources` is a parameter of type `array`:
|
|
|
|
```bash
|
|
curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
|
|
-d "import_sources[]=github" \
|
|
-d "import_sources[]=bitbucket" \
|
|
"https://gitlab.example.com/api/v4/some_endpoint
|
|
```
|
|
|
|
### `hash`
|
|
|
|
`override_params` is a parameter of type `hash`:
|
|
|
|
```bash
|
|
curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
|
|
--form "namespace=email" \
|
|
--form "path=impapi" \
|
|
--form "file=@/path/to/somefile.txt"
|
|
--form "override_params[visibility]=private" \
|
|
--form "override_params[some_other_param]=some_value" \
|
|
https://gitlab.example.com/api/v4/projects/import
|
|
```
|
|
|
|
### Array of hashes
|
|
|
|
`variables` is a parameter of type `array` containing hash key/value pairs `[{ 'key' => 'UPLOAD_TO_S3', 'value' => 'true' }]`:
|
|
|
|
```bash
|
|
curl --globoff --request POST --header "PRIVATE-TOKEN: ********************" \
|
|
"https://gitlab.example.com/api/v4/projects/169/pipeline?ref=master&variables[][key]=VAR1&variables[][value]=hello&variables[][key]=VAR2&variables[][value]=world"
|
|
|
|
curl --request POST --header "PRIVATE-TOKEN: ********************" \
|
|
--header "Content-Type: application/json" \
|
|
--data '{ "ref": "master", "variables": [ {"key": "VAR1", "value": "hello"}, {"key": "VAR2", "value": "world"} ] }' \
|
|
"https://gitlab.example.com/api/v4/projects/169/pipeline"
|
|
```
|
|
|
|
## `id` vs `iid`
|
|
|
|
Some resources have two similarly-named fields. For example, [issues](issues.md), [merge requests](merge_requests.md), and [project milestones](merge_requests.md). The fields are:
|
|
|
|
- `id`: ID that is unique across all projects.
|
|
- `iid`: additional, internal ID that is unique in the scope of a single project.
|
|
|
|
NOTE: **Note:**
|
|
The `iid` is displayed in the web UI.
|
|
|
|
If a resource has the `iid` field and the `id` field, the `iid` field is usually used instead of `id` to fetch the resource.
|
|
|
|
For example, suppose a project with `id: 42` has an issue with `id: 46` and `iid: 5`. In this case:
|
|
|
|
- A valid API call to retrieve the issue is `GET /projects/42/issues/5`
|
|
- An invalid API call to retrieve the issue is `GET /projects/42/issues/46`.
|
|
|
|
NOTE: **Note:**
|
|
Not all resources with the `iid` field are fetched by `iid`. For guidance on which field to use, see the documentation for the specific resource.
|
|
|
|
## Data validation and error reporting
|
|
|
|
When working with the API you may encounter validation errors, in which case
|
|
the API will answer with an HTTP `400` status.
|
|
|
|
Such errors appear in two cases:
|
|
|
|
- A required attribute of the API request is missing, e.g., the title of an
|
|
issue is not given
|
|
- An attribute did not pass the validation, e.g., user bio is too long
|
|
|
|
When an attribute is missing, you will get something like:
|
|
|
|
```
|
|
HTTP/1.1 400 Bad Request
|
|
Content-Type: application/json
|
|
{
|
|
"message":"400 (Bad request) \"title\" not given"
|
|
}
|
|
```
|
|
|
|
When a validation error occurs, error messages will be different. They will
|
|
hold all details of validation errors:
|
|
|
|
```
|
|
HTTP/1.1 400 Bad Request
|
|
Content-Type: application/json
|
|
{
|
|
"message": {
|
|
"bio": [
|
|
"is too long (maximum is 255 characters)"
|
|
]
|
|
}
|
|
}
|
|
```
|
|
|
|
This makes error messages more machine-readable. The format can be described as
|
|
follows:
|
|
|
|
```json
|
|
{
|
|
"message": {
|
|
"<property-name>": [
|
|
"<error-message>",
|
|
"<error-message>",
|
|
...
|
|
],
|
|
"<embed-entity>": {
|
|
"<property-name>": [
|
|
"<error-message>",
|
|
"<error-message>",
|
|
...
|
|
],
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
## Unknown route
|
|
|
|
When you try to access an API URL that does not exist you will receive 404 Not Found.
|
|
|
|
```
|
|
HTTP/1.1 404 Not Found
|
|
Content-Type: application/json
|
|
{
|
|
"error": "404 Not Found"
|
|
}
|
|
```
|
|
|
|
## Encoding `+` in ISO 8601 dates
|
|
|
|
If you need to include a `+` in a query parameter, you may need to use `%2B` instead due
|
|
to a [W3 recommendation](http://www.w3.org/Addressing/URL/4_URI_Recommentations.html) that
|
|
causes a `+` to be interpreted as a space. For example, in an ISO 8601 date, you may want to pass
|
|
a time in Mountain Standard Time, such as:
|
|
|
|
```
|
|
2017-10-17T23:11:13.000+05:30
|
|
```
|
|
|
|
The correct encoding for the query parameter would be:
|
|
|
|
```
|
|
2017-10-17T23:11:13.000%2B05:30
|
|
```
