Use the HTTP Request module with custom headers

Did you know that the HTTP Request module can fetch custom headers from the incoming message? A pretty common scenario is that you want to add a Bearer token from an external system in the HTTP Request. To achieve this, you can fetch the token from the incoming message via template syntax and use it in the Message Template as shown below. The Message Template module will then map the token value into the message.
