Documented steps

  1. Authenticate with a Railway API token to https://backboard.railway.com/graphql/v2 (Authorization: Bearer for account/workspace, Project-Access-Token for project tokens).
  2. Resolve the deployment id via the deployments query keyed by {projectId, serviceId, environmentId}.
  3. Run 'query buildLogs($deploymentId:String!, $limit:Int){ buildLogs(deploymentId:$deploymentId, limit:$limit){ timestamp message severity } }'.
  4. Set limit to number of log lines (e.g. 500).
  5. Read the returned timestamp/message/severity triples to debug a failing build.
