gRPC Support on Anypoint Platform

Implement and consume gRPC APIs as part of your API-led strategy using gRPC support in Anypoint Platform. gRPC is a high-performance, open-source framework for remote procedure calls (RPCs) that uses Protocol Buffers (protobuf) as the interface definition language. gRPC uses HTTP/2 for transport and is well-suited for server-to-server communication and microservices architectures.

Anypoint Platform supports gRPC in the following products and stages:

API-Led Journey Stage Product Versions Supported Learn More

Design Specs

Anypoint Code Builder

Protobuf 3

Design your gRPC specs (API Type: gRPC API, Protobuf 3) in Anypoint Code Builder and verify them in the API console.

Govern Specs

Anypoint API Governance

Protobuf 3

Validate your gRPC API specs against governance rulesets during the design phase. After you publish the specs to Exchange, govern them using API Governance.

Publish Specs

Anypoint Exchange

Protobuf 3

Publish your gRPC API specs to Exchange to share and promote collaboration. When implementing, you can filter by gRPC when searching for specs in Exchange.

Implement APIs

Anypoint Code Builder

Protobuf 3

Scaffold and implement gRPC specs in a Mule project using Anypoint Code Builder. Discover specs from Exchange; APIkit generates the implementation from your .proto file. The minimum Mule runtime engine requirement for this feature is Mule 4.11.

APIkit for gRPC

Protobuf 3

Scaffold and implement gRPC APIs in a Mule project from a .proto file using APIkit for gRPC. The minimum Mule runtime engine requirement for this feature is Mule 4.11.

Deploy

Runtime Fabric

Protobuf 3

Deploy your gRPC API to Runtime Fabric. When deploying a gRPC API, you must enable HTTP/2 ingress. The minimum Mule runtime engine requirement is Mule 4.11 or later.

Manage APIs

Anypoint API Manager

Protobuf 3

Create and manage your gRPC API instances and proxies; apply policies and SDLC for gRPC and HTTP/2.

Flex Gateway

Protobuf 3

Manage and govern your external gRPC services using Flex Gateway.

Connect to gRPC Services

Anypoint Connector for gRPC (gRPC Connector)

Protobuf 3

Call external gRPC services from your Mule applications using gRPC Connector
