API Key Privacy

When working with the Calais Popfly Block it is helpful to keep in mind that once you share a mashup, any information in the mashup becomes public. It is easy to have your OpenCalais API key exposed in this way.

A simple solution to this problem is shown repeatedly in the samples above. Use a User Input block to obtain the OpenCalais API key. This way, when you share your mashup, your API key is not shared with it.
