I went ahead and created the workflow for you using dummy data.
You can download it here.
As per your description, it's triggered using the keyword `wcp`, which accepts a single argument, currently `product1`, `product2`, ... , `product55`. Upon selection, the URL referenced by argument entered gets passed to the next action. There's an Open URL action waiting on the workflow's workspace, not yet connected to the trigger. Instead, a Large Type output receives the URL, allowing you to preview the URL fully for testing purposes.
