What is gRPC?

From the gRPC documentation:

gRPC is a modern, open source remote procedure call (RPC) framework that can run anywhere. It enables client and server applications to communicate transparently, and makes it easier to build connected systems.

How can I use gRPC with Tyk?

Using Tyk with your gRPC client and server is very easy. Since gRPC uses HTTP/2, you need to enable it by setting enable_http2=true for Downstream-Tyk and proxy_enable_http2=true for Tyk-Upstream connections. You also need to set your listen_path in your API definitions.

Mutual Authentication

Tyk supports Mutual Authentication in gRPC. See Mutual TLS to configure Mutual Authentication in Tyk. Now, everything will be same as default Mutual Authentication.

Basic Authentication

Tyk supports Basic Authentication in gRPC. See Basic Authentication to configure Basic Authentication in Tyk.

After setting your Tyk configuration, all you need to do is to send credentials with the correct base64 format in an Authorization header from your gRPC client.

Basic base64Encode(username:password)

Token Based Authentication

Tyk supports Token Based Authentication in gRPC. See Bearer Tokens to configure Token Based Authentication in Tyk.

After setting your Tyk configuration, all you need to do is to send a token in an Authorization header from your gRPC client.
