To expose a gRPC service as a RESTful HTTP API, you configure the Apache APISIX grpc-transcode plugin to convert incoming HTTP requests into gRPC calls, enabling broader client compatibility without modifying the backend.

Yes, protobuf definitions are required for APISIX gRPC transcoding. You must upload, manage, and reference these proto files so the plugin can accurately map service methods and serialize data between HTTP and gRPC protocols.

HTTP to gRPC transcoding handles errors and deadlines by supporting advanced features like error detail decoding and deadline enforcement, ensuring that RESTful clients receive proper failure context and timeout management.

Yes, you can use APISIX to bridge mobile or web clients with internal gRPC microservices by transcoding RESTful HTTP requests into gRPC calls, allowing external clients that only support HTTP/JSON to integrate seamlessly.

The best way to convert RESTful HTTP requests to gRPC without changing backend code is using a gateway plugin like APISIX grpc-transcode, which manages protobuf definitions and service mapping externally to expose gRPC APIs via HTTP endpoints.
