Retool connects to gRPC services by configuring a resource with the server address and proto definitions. Once set up, teams can invoke RPC methods directly from Retool apps and workflows.

Retool supports TLS-based connections and custom metadata headers for gRPC authentication. Credentials and certificates are stored as encrypted Retool resources.

Yes. Retool supports unary and server-streaming gRPC calls, including write operations. Teams add confirmation steps and approval workflows in Retool to ensure mutations are intentional.

gRPC connection credentials and TLS certificates are stored as encrypted Retool resources and are never exposed to end users.

Yes. Retool supports environment-specific gRPC resources, allowing teams to point development and production apps at different gRPC servers or use different credentials per environment.

Retool supports server-streaming gRPC calls, allowing apps to consume streamed responses from gRPC services. Client-streaming and bidirectional-streaming support depends on the specific Retool version and configuration.
