GitLab API
The GitLab API provides a way to interact with GitLab from external applications. It’s a RESTful API that allows you to perform actions like creating projects, managing users, and triggering pipelines.
This outline provides a comprehensive overview of the GitLab API, its endpoints, and how to use it effectively.
Accessing the API
The GitLab API is available at /api/v4
of your GitLab instance. For example, the GitLab.com API is available at https://gitlab.com/api/v4.
You can access the API using any HTTP client.
Authentication
To use the GitLab API, you need to authenticate. Here are the available authentication methods:
Personal Access Token: You can create a personal access token in your GitLab profile, which provides access to the API. You can specify the scopes of the token, giving it access to specific resources. https://docs.gitlab.com/ee/api/README.html#authentication
OAuth 2.0: OAuth 2.0 allows applications to request access to user data and resources on GitLab without needing to store the user’s password. https://docs.gitlab.com/ee/integration/oauth_provider.html
API Key: You can use API keys in your application to authenticate against the GitLab API. https://docs.gitlab.com/ee/api/README.html#authentication
Endpoints
The GitLab API offers various endpoints, each responsible for managing a specific area of the GitLab platform. Here are some examples:
- Projects: Create, update, delete, and manage projects. https://docs.gitlab.com/ee/api/projects.html
- Repositories: Manage repository content, branches, tags, and commits. https://docs.gitlab.com/ee/api/repositories.html
- Users: Create, manage, and list users. https://docs.gitlab.com/ee/api/users.html
- Issues: Create, assign, and track issues in your projects. https://docs.gitlab.com/ee/api/issues.html
- Merge Requests: Create, manage, and merge merge requests. https://docs.gitlab.com/ee/api/merge_requests.html
- Pipelines: Trigger, monitor, and manage pipelines. https://docs.gitlab.com/ee/api/pipelines.html
- Jobs: Get information about jobs within a pipeline. https://docs.gitlab.com/ee/api/jobs.html
API Response Format
The GitLab API responds with JSON-formatted data, including status codes to indicate success or failure.
Using the API
To use the GitLab API, you need to make HTTP requests to the appropriate endpoint using your chosen HTTP client. You need to include authentication details in your requests, as outlined in the authentication section.
Example
This example uses the curl
command to retrieve a list of projects.
curl --header "PRIVATE-TOKEN: YOUR_PRIVATE_TOKEN" "https://gitlab.com/api/v4/projects"
Replace YOUR_PRIVATE_TOKEN
with your actual personal access token.
The response will be in JSON format, containing a list of projects.
