I used server-to-server RPC calls from the client side also as unauthenticated public APIs. However, these calls require the `httpKey` in the request parameters.
Is there a way to create a public HTTP RPC in Nakama that doesn’t require an `httpKey`?

Hello @surajTLabs,
You can register custom http handlers (without auth or custom auth you have to implement yourself) with this new [register function](https://github.com/heroiclabs/nakama/blob/v3.25.0/sample_go_module/sample.go#L58).
This is only supported in Go and was introduced a couple of releases ago, so if you’re on an older one you may need to upgrade.
Best.

Is this only available in Go runtime.?

Yes `registerHttp` is only available in the Go runtime.
