Configuring the REST API is very simple.
This API is designed to provide easy and secure access to geo information on your site sending simple POST or GET requests and receiving JSON formatted data. Through this API, you can easily connect via any programming language that allows cross domain communication.
Each installation of the CF Geo Plugin has a unique API KEY. This key does not change and remains fixed. The Secret API KEY can be modified and is generated by a simple click of a button. This secret API key is used to generate a one-time secret key that is obtained by authentication (next part of this documentation).
