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. version: '1.0' contact: name: Render url: https://render.com license: name: Proprietary url: https://render.com/terms servers: - url: https://api.render.com/v1 description: Render Public API security: - bearerAuth: [] tags: - name: Environment Variables description: Per-service environment variables and secret files. paths: /services/{serviceId}/env-vars: parameters: - $ref: '#/components/parameters/ServiceId' get: operationId: listEnvVars tags: - Environment Variables summary: List environment variables responses: '200': description: A list of environment variables. put: operationId: replaceEnvVars tags: - Environment Variables summary: Replace environment variables requestBody: required: true content: application/json: schema: type: array items: type: object responses: '200': description: The updated environment variables. /services/{serviceId}/env-vars/{envVarKey}: parameters: - $ref: '#/components/parameters/ServiceId' - name: envVarKey in: path required: true schema: type: string get: operationId: retrieveEnvVar tags: - Environment Variables summary: Retrieve an environment variable responses: '200': description: The requested environment variable. put: operationId: upsertEnvVar tags: - Environment Variables summary: Add or update an environment variable requestBody: required: true content: application/json: schema: type: object properties: value: type: string responses: '200': description: The upserted environment variable. delete: operationId: deleteEnvVar tags: - Environment Variables summary: Delete an environment variable responses: '204': description: The environment variable was deleted. /services/{serviceId}/secret-files: parameters: - $ref: '#/components/parameters/ServiceId' get: operationId: listSecretFiles tags: - Environment Variables summary: List secret files responses: '200': description: A list of secret files. put: operationId: replaceSecretFiles tags: - Environment Variables summary: Replace secret files requestBody: required: true content: application/json: schema: type: array items: type: object responses: '200': description: The updated secret files. /services/{serviceId}/secret-files/{secretFileName}: parameters: - $ref: '#/components/parameters/ServiceId' - name: secretFileName in: path required: true schema: type: string put: operationId: upsertSecretFile tags: - Environment Variables summary: Add or update a secret file requestBody: required: true content: application/json: schema: type: object responses: '200': description: The upserted secret file. delete: operationId: deleteSecretFile tags: - Environment Variables summary: Delete a secret file responses: '204': description: The secret file was deleted. components: parameters: ServiceId: name: serviceId in: path required: true schema: type: string securitySchemes: bearerAuth: type: http scheme: bearer description: Render API key created in the Render Dashboard, sent as an Authorization Bearer token.
