//  See Global Unlock Sample for sample code.

//  First, concatenate these into a plaintext string using the following order:
//  
//      Capitilized method of the request. E.g. "POST"
//      The URI path
//      The query parameters sorted alphabetically and concatenated together into a URL friendly format: param1=ABC&param2=XYZ
//      The request body as a string if one exists
//      All parts are then concatenated together with an ampersand. The result resembles something like this:
//  
//  "POST&/partners/api/accounts&api_key=f9a7c8ebdfd34beaf260d9b0296c7059&api_timestamp=1401803554&{ ... request body ... }"
