Scheduling gRPC and GraphQL Requests with Postman Monitors (Beta)

Postman Monitors now support gRPC and GraphQL requests in beta, allowing teams to schedule existing collection requests with their configured authentication, variables, and test scripts rather than relying on separate synthetic-monitoring tools or custom cron jobs. Supported capabilities include unary and server-streaming gRPC calls, plus GraphQL queries and mutations over HTTP, with validation using familiar Postman scripting objects such as pm.response; GraphQL checks should inspect response errors and data rather than HTTP status alone, since GraphQL can return errors alongside a 200 response. Server-streaming requests can be tested per message or after completion, although the beta currently limits client-streaming and bidirectional calls to one client message and does not yet support GraphQL subscriptions. Users can configure monitor frequency, regions, environments, and notifications, while the guidance recommends dedicated secret-based monitor environments and narrowly focused collections for clearer incident diagnosis. Postman is seeking beta feedback through its GitHub support repository, particularly on streaming patterns, subscription use cases, and desired assertion helpers, with multi-message streaming, subscriptions, and richer stream testing planned for future releases.
