How we built it: gRPC support

In a recent livestream event, members of the Postman development team, including Technical Lead Josh Wise and Design Engineer Shobhit Katikia, discussed the introduction of gRPC support in Postman, highlighting its differences from HTTP-based APIs. gRPC is a binary-only protocol used extensively in internal-facing microservices due to its support for streamed data, structured payloads, and its efficiency and low latency compared to traditional HTTP APIs. The team showcased upcoming Postman releases and demonstrated new UI changes and enhancements to the API client, discussing how the integration of gRPC support has influenced their engineering strategies. The event also provided insights into the development of new mock server infrastructure, including mock server support for gRPC and the use of "seed" data to regenerate "pseudo-random" content, offering a preview of future changes in Postman.
