# Query users with GraphQL **(FREE)**
|
|
|
|
This page describes how you can use the GraphiQL explorer to query users.
|
|
|
|
You can run the same query directly via a HTTP endpoint, using `cURL`. For more information, see our
|
|
guidance on getting started from the [command line](getting_started.md#command-line).
|
|
|
|
The [example users query](#set-up-the-graphiql-explorer) looks for a subset of users in
|
|
o
|
|
a GitLab instance either by username or
|
|
[Global ID](../../development/api_graphql_styleguide.md#global-ids).
|
|
The query includes:
|
|
|
|
- [`pageInfo`](#pageinfo)
|
|
- [`nodes`](#nodes)
|
|
|
|
## pageInfo
|
|
|
|
This contains the data needed to implement pagination. GitLab uses cursor-based
|
|
[pagination](getting_started.md#pagination). For more information, see
|
|
[Pagination](https://graphql.org/learn/pagination/) in the GraphQL documentation.
|
|
|
|
## nodes
|
|
|
|
In a GraphQL query, `nodes` is used to represent a collection of [`nodes` on a graph](https://en.wikipedia.org/wiki/Vertex_(graph_theory)).
|
|
In this case, the collection of nodes is a collection of `User` objects. For each one,
|
|
we output:
|
|
|
|
- Their user's `id`.
|
|
- The `membership` fragment, which represents a Project or Group membership belonging
|
|
to that user. Outputting a fragment is denoted with the `...memberships` notation.
|
|
|
|
The GitLab GraphQL API is extensive and a large amount of data for a wide variety of entities can be output.
|
|
See the official [reference documentation](reference/index.md) for the most up-to-date information.
|
|
|
|
## Set up the GraphiQL explorer
|
|
|
|
This procedure presents a substantive example that you can copy and paste into GraphiQL
|
|
explorer. GraphiQL explorer is available for:
|
|
|
|
- GitLab.com users at [https://gitlab.com/-/graphql-explorer](https://gitlab.com/-/graphql-explorer).
|
|
- Self-managed users at `https://gitlab.example.com/-/graphql-explorer`.
|
|
|
|
1. Copy the following code excerpt:
|
|
|
|
```graphql
|
|
{
|
|
users(usernames: ["user1", "user3", "user4"]) {
|
|
pageInfo {
|
|
endCursor
|
|
startCursor
|
|
hasNextPage
|
|
}
|
|
nodes {
|
|
id
|
|
username,
|
|
publicEmail
|
|
location
|
|
webUrl
|
|
userPermissions {
|
|
createSnippet
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
1. Open the [GraphiQL explorer tool](https://gitlab.com/-/graphql-explorer).
|
|
1. Paste the `query` listed above into the left window of your GraphiQL explorer tool.
|
|
1. Select **Play** to get the result shown here:
|
|
|
|
|
|
|
|
NOTE:
|
|
[The GraphQL API returns a GlobalID, rather than a standard ID.](getting_started.md#queries-and-mutations) It also expects a GlobalID as an input rather than
|
|
a single integer.
|
|
|
|
This GraphQL query returns the specified information for the three users with the listed username. Since the GraphiQL explorer uses the session token to authorize access to resources,
|
|
the output is limited to the projects and groups accessible to the currently signed-in user.
|
|
|
|
If you've signed in as an instance administrator, you would have access to all records, regardless of ownership.
|
|
|
|
If you are signed in as an administrator, you can show just the matching administrators on the instance by adding the `admins: true` parameter to the query changing the second line to:
|
|
|
|
```graphql
|
|
users(usernames: ["user1", "user3", "user4"], admins: true) {
|
|
...
|
|
}
|
|
```
|
|
|
|
Or you can just get all of the administrators:
|
|
|
|
```graphql
|
|
users(admins: true) {
|
|
...
|
|
}
|
|
```
|
|
|
