Render Environment Variables API

openapi: 3.0.3
info:
  title: Render Blueprints Environment Variables API
  description: The Render REST API programmatically manages resources on the Render cloud application platform (PaaS). It exposes almost all of the functionality available in the Render Dashboard - services (web services, static sites, private services, background workers, cron jobs), deploys, custom domains, environment variables and groups, secret files, managed Postgres and Key Value (Redis-compatible) datastores, one-off jobs, persistent disks, Blueprints, projects and environments, workspaces and members, registry credentials, metrics, logs, and webhooks. All requests are authenticated with a Bearer API key created in the Render Dashboard. Real-time log streaming is available over a WebSocket surface (see the companion AsyncAPI document). This OpenAPI document models the REST surface; a subset of endpoints is confirmed against Render's public API reference and the remainder follow Render's documented, consistent REST conventions.
