+The second parameter is for setting the region.

 For example:
 ```php

-Or if you prefer you can use the static methods `initEU` to access the European region.

-If you need access to other regions, you can use:
 
-- `initUS()` for the US region
-- `initAP()` for the Asian Pacific region
-- `initCA()` for the Canadian region
-- `initCN()` for the China region.
