How to get only specific fields in Gitlab API response?

Question

For example I want to receive only project names: https://gitlab.com/api/v4/groups/:id/projects?fields=name

Is that possible?

Answer 1

That's not possible in the REST API. But, GitLab is working on GraphQL support, and you'd be able to express that in GraphQL.

https://docs.gitlab.com/ee/api/graphql/

To iterate on Vonc & King Chung Huang 's answers, using the following GraphQL query, you can get only the name field of the projects inside your group :

{
  group(fullPath: "your_group_name") {
    projects {
      nodes {
        name
      }
    }
  }
}

You can go to the following URL : https://$gitlab_url/-/graphql-explorer and past the above query

Using curl & jq :

gitlab_url=<your gitlab host>
access_token=<your access token>
group_name=<your group name>

curl -s -H "Authorization: Bearer $access_token" \
     -H "Content-Type:application/json" \
     -d '{ 
          "query": "{ group(fullPath: \"'$group_name'\") { projects { nodes { name }}}}"
      }' "https://$gitlab_url/api/graphql" | jq '.'

GitLab 1.11 (May 2019) has now introduced a "basic support for group GraphQL queries "

GraphQL APIs allows users to request exactly the data they need, making it possible to get all required data in a limited number of requests.

In this release, GitLab is now supporting basic group information support in the GraphQL API.

See Issue 60786 and documentation: "Available queries"

A first iteration of a GraphQL API includes the following queries

• project : Within a project it is also possible to fetch a mergeRequest by IID.
• group : Only basic group information is currently supported.
