Hiding your API Key


One of the most common uses of the what3words API is within browser-based applications. For example, you might be using the what3words AutoSuggest jQuery plugin to allow easy capture of 3 word addresses on your website. In cases like these, where a client-side JavaScript application is making calls to the public what3words API, there is a danger that you’re API key will be both visible inside your JavaScript application, and over the network.

To mitigate against this, you can hide your API key by proxying API calls through a proxy application running on your server.
