Build A Translation REST API With Watson, Node-RED, and Bluemix

Today I was looking at some of the new Watson nodes for Node-RED created by my colleague James Thomas and was presently surprised how easy it was to start using the Watson services in Node-RED.  (I am not sure why, I was surprised everything in Node-RED seems to be easy)  For one of my upcoming presentations I put together a simple flow for a REST API that uses the Watson Machine Translation service in order to translate text POSTed to an API endpoint.  Below is a video I created of how easy this was to do.

If you are interested in adding the flow to your Node-RED instance copy the below JSON and import into a sheet.  Note: you will need a Watson Machine Translation service bound to your Node-RED app in order for the flow to work.
