Lando

Poll the public landing-job endpoint after you submit a try push or commit through Lando.

Prerequisites

The read-only API does not need authentication. Use curl and jq.

Usage

curl -fsS "https://lando.moz.tools/landing_jobs/<JOB_ID>/" \
  | jq '{status, commit_id, error, updated_at}'

Poll at a moderate interval until status is LANDED, FAILED, or CANCELLED. Report commit_id for a landed job and error for a failed job.

Gotchas

• Status values are uppercase.
• The landed commit field is commit_id, not landed_commit_id.
• A job can end as CANCELLED as well as FAILED or LANDED.
• Use lando.moz.tools (instance lando-prod-2025, the landoInstance in the Treeherder URL that mach try prints). The old api.lando.services.mozilla.com host is a different instance whose job IDs overlap, so it returns unrelated jobs instead of an error.
• Keep the trailing slash. Without it the endpoint returns a 301 redirect.
