# 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 ... }"
