How to make AJAX post request with Certificate

I'm working on trying to access data from the Bloomberg API using javascript and AJAX from Pebble, and this is the example they show on their github

 curl -X POST 'http://ift.tt/1G7bRng' \
--cacert bloomberg.crt \
--cert   client.crt    \
--key    client.key    \
--data @- <<EOF
 { "securities": ["IBM US Equity", "AAPL US Equity"],
   "fields": ["PX_LAST", "OPEN"],
   "startDate": "20120101",
   "endDate": "20120105",
   "periodicitySelection": "DAILY" }
   EOF

I already have the certificates, I am just confused as to how to specify the certificates as args to the post request.

This is the documentation for what I am using. http://ift.tt/1G5Wjx2 Do I just specify these args under the headers option?
