REST API resources are documented in Markdown under /doc/api. Each resource has its own Markdown file, which is linked from

When modifying the Markdown, also update the corresponding OpenAPI definition if one exists for the resource. If not, consider creating one. Match the latest OpenAPI 3.0.x specification. (For more information, see the discussion in this issue.)

In the Markdown doc for a resource (AKA endpoint):

  • Every method must have the REST API request. For example:

    GET /projects/:id/repository/branches
  • Every method must have a detailed description of the parameters.

  • Every method must have a cURL example.

  • Every method must have a response body (in JSON format).

  • If an attribute is available only to higher level tiers than the other parameters, add the appropriate inline tier badge. Put the badge in the Attribute column, like the **(<tier>)** code in the following template.

API topic template

Use the following template to help you get started. Be sure to list any required attributes first in the table.

## Descriptive title

> Version history note.

One or two sentence description of what endpoint does.

METHOD /endpoint

Supported attributes:

| Attribute                | Type     | Required               | Description           |
| `attribute`              | datatype | **{check-circle}** Yes | Detailed description. |
| `attribute` **(<tier>)** | datatype | **{dotted-circle}** No | Detailed description. |
| `attribute`              | datatype | **{dotted-circle}** No | Detailed description. |
| `attribute`              | datatype | **{dotted-circle}** No | Detailed description. |

Example request:

curl --header "PRIVATE-TOKEN: <your_access_token>" ""

Example response:


Adjust the version history note accordingly to describe the GitLab release that introduced the API call.

Method description

Use the following table headers to describe the methods. Attributes should always be in code blocks using backticks (`).

Sort the table by required attributes first, then alphabetically.

| Attribute                    | Type          | Required               | Description                                          |
| `title`                      | string        | **{check-circle}** Yes | Title of the issue.                                 |
| `assignee_ids` **(PREMIUM)** | integer array | **{dotted-circle}** No | IDs of the users to assign the issue to.         |
| `confidential`               | boolean       | **{dotted-circle}** No | Sets the issue to confidential. Default is `false`. |

Rendered example:

Attribute Type Required Description
title string {check-circle} Yes Title of the issue.
assignee_ids (PREMIUM) integer array {dotted-circle} No IDs of the users to assign the issue to.
confidential boolean {dotted-circle} No Sets the issue to confidential. Default is false.

For information about writing attribute descriptions, see the GraphQL API description style guide.

cURL commands

  • Use as an endpoint.
  • Wherever needed use this personal access token: <your_access_token>.
  • Always put the request first. GET is the default so you don't have to include it.
  • Wrap the URL in double quotes (").
  • Prefer to use examples using the personal access token and don't pass data of username and password.
Methods Description
--header "PRIVATE-TOKEN: <your_access_token>" Use this method as is, whenever authentication needed.
--request POST Use this method when creating new objects
--request PUT Use this method when updating existing objects
--request DELETE Use this method when removing existing objects

cURL Examples

The following sections include a set of cURL examples you can use in the API documentation.

WARNING: Do not use information for real users, URLs, or tokens. For documentation, refer to our relevant style guide sections on Fake user information, Fake URLs, and Fake tokens.

Simple cURL command

Get the details of a group:

curl --header "PRIVATE-TOKEN: <your_access_token>" ""

cURL example with parameters passed in the URL

Create a new project under the authenticated user's namespace:

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" ""

Post data using cURL's --data

Instead of using --request POST and appending the parameters to the URI, you can use cURL's --data option. The example below will create a new project foo under the authenticated user's namespace.

curl --data "name=foo" --header "PRIVATE-TOKEN: <your_access_token>" ""

Post data using JSON content

This example creates a new group. Be aware of the use of single (') and double (") quotes.

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" --header "Content-Type: application/json" \
     --data '{"path": "my-group", "name": "My group"}' ""

For readability, you can also set up the --data by using the following format:

curl --request POST \
--url "" \
--header "content-type: application/json" \
--header "PRIVATE-TOKEN: <your_access_token>" \
--data '{
  "path": "my-group",
  "name": "My group"

Post data using form-data

Instead of using JSON or URL-encoding data, you can use multipart/form-data which properly handles data encoding:

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" --form "title=ssh-key" \
     --form "key=ssh-rsa AAAAB3NzaC1yc2EA..." ""

The above example is run by and administrator and will add an SSH public key titled ssh-key to user's account which has an ID of 25.

Escape special characters

Spaces or slashes (/) may sometimes result to errors, thus it is recommended to escape them when possible. In the example below we create a new issue which contains spaces in its title. Observe how spaces are escaped using the %20 ASCII code.

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" ""

Use %2F for slashes (/).

Pass arrays to API calls

The GitLab API sometimes accepts arrays of strings or integers. For example, to exclude specific users when requesting a list of users for a project, you would do something like this:

curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" --data "skip_users[]=<user_id>" \
     --data "skip_users[]=<user_id>" "<project_id>/users"
