Zoho Generate API Key

#!/bin/bash

# This script generates Zoho API tokens. It requires 'jq' to parse the output.
# If you have any questions, you can find me as xrobau pretty much everywhere
# (gmail, twitter, facebook, etc)
#
# Note you can provide params if you want:
# ./gentoken.sh email@addr 1000.clientid bbbbbSECRETbbbbb http://uri
#
# Also - the URI does not need to be valid. It just needs to be a URI, and
# it does not need to match the domain. I use 'example.com' and 'http://uri'
#
# --xrobau
