GLQL API

Tier: Free, Premium, Ultimate
Offering: GitLab.com, GitLab Self-Managed, GitLab Dedicated

Use this API to execute GitLab Query Language (GLQL) queries programmatically. GLQL provides a simplified query language for searching and filtering GitLab resources such as issues, merge requests, and epics across projects and groups.

Prerequisites:

The group or project must allow access to its data.
For private groups and projects, you must use a personal access token with appropriate permissions.

Execute a GLQL query

Executes a GLQL query to search and filter GitLab resources.

POST /glql

This endpoint rate-limits queries based on the query SHA. Identical queries that time out are tracked and might be temporarily blocked if executed too frequently.

Supported attributes:

Attribute	Type	Required	Description
`glql_yaml`	string	Yes	The GLQL query with optional YAML configuration. Maximum size: 10,000 bytes (10 KB). See Query formats for details.
`after`	string	No	Cursor for pagination. Use the `data.pageInfo.endCursor` value from a previous query to fetch the next page of results.

Query formats

The glql_yaml parameter accepts the YAML format with a query key:

fields: id,title,author
group: my-group
limit: 10
sort: created desc
query: state = opened

Configuration options

The following configuration options can be included in the YAML:

Option	Type	Required	Description
`fields`	string	No	Comma-separated list of fields to return. Default: `title`. See Available fields.
`group`	string	No	Scope the query to a specific group. Cannot be used with `project`. If `group` is also specified in the query, the query value takes precedence.
`limit`	integer	No	Maximum number of results to return. Must be between 1 and 100. Default: `100`.
`project`	string	No	Scope the query to a specific project. Format: `group/project`. If `project` is also specified in the query, the query value takes precedence.
`sort`	string	No	Sort order for results. Format: `field direction` (for example, `created asc` or `created desc`).

Available fields

The fields configuration option is defined by GLQL’s available fields.

GLQL query syntax

The query syntax is defined by GLQL.

Response attributes

If successful, returns 200 OK and the following response attributes:

Attribute	Type	Description
`data`	object	Contains the query results.
`data.count`	integer	Total number of matching results.
`data.nodes`	array	Array of matching resources with requested fields.
`data.pageInfo`	object	Pagination information.
`data.pageInfo.endCursor`	string	Cursor for fetching the next page of results.
`data.pageInfo.hasNextPage`	boolean	Indicates if more results are available.
`data.pageInfo.hasPreviousPage`	boolean	Indicates if previous results are available.
`data.pageInfo.startCursor`	string	Cursor for fetching the previous page of results.
`error`	string	Error message if the query failed.
`fields`	array	Array of field definitions.
`fields[].key`	string	The unique field identifier.
`fields[].label`	string	The human-readable field name.
`fields[].name`	string	The common field name that unifies similar fields. For example, `created` and `createdAt` keys have the name `createdAt`.
`success`	boolean	Indicates if the query was successful.

To fetch the next page, use the endCursor value from the previous response:

curl --request POST \
  --header "PRIVATE-TOKEN: <your_access_token>" \
  --header "Content-Type: application/json" \
  --data '{
    "glql_yaml": "limit: 2\nquery: group = \"my-group\" AND state = opened",
    "after": "eyJpZCI6IjIifQ=="
  }' \
  --url "https://gitlab.example.com/api/v4/glql"

Rate limiting

The GLQL API implements rate limiting based on the SHA-256 hash of the query. Queries that time out are tracked. If a particular query that is timing out is executed too frequently, it is temporarily blocked.

When rate limited, the API returns a 429 Too Many Requests status code with an error message:

{
  "error": "Query temporarily blocked due to repeated timeouts. Please try again later or narrow your search scope."
}

Error handling

The API returns the following HTTP status codes:

Status code	Description
`200 Success`	Query executed successfully.
`400 Bad Request`	Invalid query syntax, missing required parameters, or input exceeds size limit.
`401 Unauthorized`	Authentication required or invalid credentials.
`403 Forbidden`	Insufficient permissions or missing required OAuth scope.
`429 Too Many Requests`	Query rate limit exceeded.
`500 Internal Server Error`	Server error during query execution.

Error response examples

Missing required parameter:

{
  "error": "glql_yaml is missing, glql_yaml is empty"
}

Invalid GLQL syntax:

{
  "error": "400 Bad request - Error: Unexpected `invalid syntax @@@ ###`, expected operator (one of IN, =, !=, >, or <)"
}

Input size exceeded:

{
  "error": "400 Bad request - Input exceeds maximum size"
}

Non-existent project:

{
  "error": "400 Bad request - Error: Project does not exist or you do not have access to it"
}

Non-existent group:

{
  "error": "400 Bad request - Error: Group does not exist or you do not have access to it"
}

Rate limit exceeded:

{
  "error": "Query temporarily blocked due to repeated timeouts. Please try again later or narrow your search scope."
}

Invalid field

{
  "error": "Field 'title' doesn't exist on type 'WorkItem' (Did you mean `title`?)"
}

GraphQL bad request errors are passed through to the API error field when applicable with the 400 error code.

Limits and constraints

The GLQL API has the following limits:

Maximum input size: 10,000 bytes (10 KB) for the glql_yaml parameter.
Maximum query limit: 100 results per request.
Default limit: 100 results when not specified.
Pagination: Only forward pagination is supported using the after attribute with the endCursor value from a previous response.
Rate limiting: Queries are rate-limited based on query SHA-256 hash.
