delete-workflow-run.sh

# Requirements: Github Client (gh) and JQ tool (jq)

# 1 - Change: OWNER, REPO
# 2 - Execute one time to get all workflows IDs
# 3 - Change: WORKFLOW_ID

OWNER=<your user/org name>
REPO=<repo name>

# list workflows
gh api -X GET /repos/$OWNER/$REPO/actions/workflows | jq '.workflows[] | .name,.id'

# copy the ID of the workflow you want to clear and set it
WORKFLOW_ID=<workflow id>

# list runs
gh api -X GET /repos/$OWNER/$REPO/actions/workflows/$WORKFLOW_ID/runs | jq '.workflow_runs[] | .id'

# delete runs (you'll have to run this multiple times if there's many because of pagination)
gh api -X GET /repos/$OWNER/$REPO/actions/workflows/$WORKFLOW_ID/runs | jq '.workflow_runs[] | .id' | xargs -I{} gh api -X DELETE /repos/$OWNER/$REPO/actions/runs/{}
