v1.1 Added support for Sandbox Mode and Silent Bcc. Removed some unnecessary quotation in calculations and changed message body from JSONString to JSONRaw.
v1.2 Fixed issue with Silent BCC option. Thanks to cmcleod and @dan_brogan for confirming this issue.
v1.3 Fixed issue with JSON syntax: corrected sanbox to sandbox (by wimmmmm)
Why the new file? Jive is not really user friendly and in the process of updating the original was deleted. Oh well. Hopefully people can communicate on the discussion topic at FileMaker and SendGrid integration and comments will not be lost in any future updates.
