Hi @Abinav Mohan

I checked the feasibility of gRPC integration in OutSystems 11. Based on the available documentation and community discussions, OutSystems 11 does not provide native support for consuming or exposing gRPC services directly. The platform's supported integration mechanisms are primarily REST, SOAP, external databases, and custom extensions.

For scenarios requiring gRPC integration, the recommended approaches are:

Develop a .NET extension using Integration Studio that acts as a gRPC client and exposes actions to OutSystems applications.

Use an external middleware or API gateway (e.g., ASP.NET, Node.js, Java) to translate REST requests to gRPC and vice versa.

Create a REST wrapper around the gRPC service and consume it from OutSystems using the standard REST integration capabilities.

Conclusion: Direct gRPC integration is not supported natively in OutSystems 11. A .NET extension or an intermediary integration layer is required to connect with gRPC services.
