Courier Ruby SDK

The Courier Ruby SDK provides typed access to the Courier REST API from any Ruby 3.2+ application. It ships with Yard docstrings, RBS and RBI type definitions for Sorbet, and uses net/http with connection pooling.

Add to your Gemfile:

gem "trycourier", "~> 4.7"

Then run bundle install.

require "bundler/setup"
require "courier"

client = Courier::Client.new

response = client.send_.message(
  message: {
    to: { email: "you@example.com" },
    content: {
      title: "Hello from Courier!",
      body: "Your first notification, sent with the Ruby SDK."
    }
  }
)

puts response.request_id

The client reads COURIER_API_KEY from your environment automatically. You can also pass it explicitly: Courier::Client.new(api_key: "your-key").

Note: The method is send_ (with trailing underscore) because send is a reserved method in Ruby.
