## Describe the problem/error/question

We have an internal Python-based backend that exposes **gRPC APIs**. We want to call these APIs as part of our **n8n workflows**.

Specifically:

- From **n8n Cloud** , how can we call a gRPC endpoint?
- Is there any native or recommended support for gRPC?
- Can we use `Execute Command` on self-hosted n8n to run a gRPC CLI client?
- What is the recommended workaround for n8n Cloud where shell access is restricted?

If gRPC isn’t directly supported, can we:

- Wrap our gRPC service in an HTTP interface (e.g., with Flask/FastAPI)?
- Use `HTTP Request` or `Webhook` nodes to send input and get the gRPC response back?

We’re looking for the cleanest and most reliable way to integrate our gRPC APIs with n8n.

## What is the error message (if any)?

No specific error — we’re asking how to integrate gRPC into n8n workflows.

## Please share your workflow

We want to call a gRPC API from within a standard workflow:  
Trigger → [Call gRPC API] → Output

## Share the output returned by the last node

Not applicable — this is a design/integration question.

## Information on your n8n setup

- **n8n version:** Cloud (latest)
- \*\*Database (default: SQLite):\*\*Cloud-managed (PostgreSQL assumed)
- **n8n EXECUTIONS\_PROCESS setting (default: own, main):**
- **Running n8n via (Docker, npm, n8n cloud, desktop app):**
- **Operating system:**
