This includes adding documentation, scripting, testing, and every other feature that you love in Postman. Firstly, gRPC support is still in beta, so we’ll be making constant improvements towards integrating gRPC into the rest of the Postman ecosystem. GRPC is a powerful new improvement for the Postman API Platform, but there is still much more ahead.

How to use streaming methods in gRPC What’s next for gRPC? We’ve added some powerful search and filtering options, so you can eliminate noise and hone in on exactly what you’re looking for. This gives you a complete view of what’s happening, which makes debugging a breeze.Īt Postman, we really care about making the developer experience seamless (after all, so many of us are developers ourselves!), so the event timeline is packed with functionality. When using a method like this, Postman will automatically show a unified timeline of all events occurring on the connection. Some methods in gRPC allow you to stream multiple payloads to the server, or allow the server to send multiple payloads in response. In the future, we hope to provide these same features for other API schemas, like OpenAPI and AsyncAPI. This is all possible because Protobuf definitions are API schemas. But it doesn’t stop there: Postman can generate an entire example message with a single click! Autocomplete and type annotations in gRPCĪs you can see, Postman becomes pretty smart when armed with a Protobuf definition. You can even hover over a JSON field to discover its Protobuf type (e.g., sint32, bytes, etc.).
This will speed up your testing and help prevent typos, as if you’re coding in your own IDE. While composing gRPC messages, Postman will provide autocomplete hints, powered by the Protobuf definition that you’re using. All of the servers you care about will be just a click away! Stay tuned for this update. In the near future, you’ll be able to save gRPC requests, so you won’t need to repeat these steps often. How to invoke a gRPC method using Postman Type the address of your gRPC server into the URL bar.Ĭlick on the Protobuf definition selector to upload your proto file. Postman supports some pretty advanced workflows, but you can still get started in just a few steps: Synchronize the proto files in your API with your repository on Github, Bitbucket, Gitlab, or Azure Repos.Import, author, share, and inspect Protobuf definitions with syntax highlighting and autocomplete.Advanced streaming features, such as searching and filtering streamed messages.Variable interpolation using environments.Send metadata, and view incoming metadata.Automatically generate example messages with a single click.Load services using gRPC server reflection.
Client-side type-checking and type annotations (Pro tip: while composing your message, hover over a field name to see its Protobuf type).Enjoy autocomplete while composing messages (powered by the Protobuf definition being used).Call unary, client-streaming, server-streaming, and bidirectional-streaming gRPC methods.In addition, you can save your Protobuf definitions to the Postman cloud, allowing you to share them with your organization, collaborate, and manage them as part of your API lifecycle. Upon loading your API’s Protobuf definition (.proto file), Postman will automatically gain an understanding of all services and methods available and generate example payloads for each method, which means you can get testing as quickly as possible. You can now test your gRPC APIs with Postman v9.7.1 and above. But we’re not stopping there! The world’s gRPC developers can celebrate: we are excited to announce first-class support for gRPC in Postman is currently in open beta. Already, Postman users enjoy the interoperability of using an API platform that also understands WebSockets, Socket.IO, and GraphQL. Those who have been following Postman’s latest releases will know that we’ve been branching out from our roots in HTTP.
