Calls a unary method on a gRPC service.

A gRPC node with target, service, method, and request fields A gRPC node with target, service, method, and request fields

Fields

  • Target , a template field, e.g. ${string.host}:443.
  • Service , the fully-qualified service name, as discovered via reflection.
  • Method , the unary method name on that service.
  • Request , a multiline JSON template matching the request message’s shape.
  • TLS , a dropdown: plaintext or tls.
  • Metadata , optional, added via the menu → Add Metadata (gRPC’s equivalent of HTTP headers , the menu item is labeled “Add Metadata”, not “Add Header”).

Template placeholders across Target/Request/Metadata become input ports , see Template Syntax Reference.

Note

Service and Method rely on the target server exposing gRPC reflection. If your service doesn’t expose it, you won’t get autocomplete for these fields.

Output

The response lands on a persistent data output port that holds a steady pulse rather than a one-shot flash , feed it into a Get JSON Value Node to pull out a specific field.
