+You can pass options to the Faraday connection block in the `connection` block:
+
+```ruby
+api = Hyperclient.new('https://grape-with-roar.herokuapp.com/api') do |client|
+  client.connection(ssl: { verify: false }) do |conn|
+    conn.use Faraday::Request::OAuth
+  end
+end
+```
+
+Or when using the default connection configuration you can use `faraday_options`:
+
+```ruby
+api = Hyperclient.new('https://grape-with-roar.herokuapp.com/api') do |client|
+  client.faraday_options = { ssl: { verify: false } }
+end
+```
+
 You can build a new Faraday connection block without inheriting default middleware by specifying `default: false` in the `connection` block.
