Documented steps
POST the variables query to https://backboard.railway.com/graphql/v2 with an Authorization header (Bearer credential) for account/workspace/OAuth tokens, or a Project-Access-Token header for project tokens.
Use the variables query with projectId, environmentId, and serviceId args to get resolved values for that service.
Omit serviceId to get the shared variables for an environment instead.
To see unresolved reference strings (e.g. ${{Postgres.DATABASE_URL}}) rather than resolved values, pass unrendered: true.
To see variables exactly as a deployment would resolve them, use variablesForServiceDeployment(projectId, environmentId, serviceId).
