@ -128,7 +128,7 @@ macaroon = macaroon_binary.each_byte.map { |b| b.to_s(16).rjust(2,'0') }.join
The simplest approach to use the macaroon is to include the metadata in each request as shown below.
```ruby
stub.get_info(Lnrpc::GetInfoRequest.new, metadata: {metadata: macaroon})
stub.get_info(Lnrpc::GetInfoRequest.new, metadata: {macaroon: macaroon})
```
However, this can get tiresome to do for each request. We can use gRPC interceptors to add this metadata to each request automatically. Our interceptor class would look like this.
