Get a concurrency group for a repository

Gets a specific concurrency group for a repository, including all instances in the group's queue. Returns 404 if the group is inactive or does not exist.

Optionally, pass ahead_of_run or ahead_of_job to filter the results to only the items ahead of the specified workflow run or job in the queue, plus the specified item itself (returned as the last element). This is useful for determining what is blocking a particular run or job. Returns 422 if the specified run or job is not in this concurrency group.

When using ahead_of_run, this matches workflow-level concurrency and any reusable-workflow leases held on behalf of that run. Job-level leases within the run are not considered to block the run as a whole. Use ahead_of_job to match job-level concurrency and reusable-workflow leases on the job's ancestor paths.

List concurrency groups for a workflow run

Lists all concurrency groups associated with a workflow run or its jobs.

The set of groups is derived from the run's configuration, so a group is included even when the run no longer has any items currently holding or waiting in it. In that case the group_members array will be empty. total_count reflects the number of groups the run participates in by configuration, not the number with active items.

This differs from GET /repos/{owner}/{repo}/actions/concurrency_groups/{group_name}, which returns 404 when a group has no active items. That endpoint reports the live state of a group repo-wide, while this endpoint reports the groups associated with a specific run by configuration.

Results are sorted by group name and support cursor-based pagination via before and after. The after cursor paginates forward only and does not emit a rel="prev" Link; use before to page backward from a forward page's next cursor.

OAuth app tokens and personal access tokens (classic) need the repo scope to use this endpoint with a private repository.
