Ruby Requires Chilkat v11.0.0+

ShippingEasy.com Calculate Signature for API Authentication

Demonstrates how to calculate the shippingeasy.com API signature for authenticating requests. Ruby

#  This example requires the Chilkat API to have been previously unlocked.
#  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 ... }"

#  Build the following JSON that will be the body of the request:

#  {
#    "account": {
#      "first_name": "Coralie",
