Cayenne Values in Webhook Post

I am using IFTTT to post actions so I don’t hit the notification limit. Presently I am creating an applet for each trigger. It would be very useful to parse values from the Sensor and post it in the Post Action.
In IFTTT a Post gets sent out in the format - https://maker.ifttt.com/trigger/XXXXXX/with/key/XXXXXXXXXXXXXXXXXX?value1=SOMEWORDS
the IFTTT function will send a post with the SOMEWORDS in a SMS or Phone Call. I’d like to use sensor values as well. I am not sure of the format to put in value1. IFTTT allows value1, value2, and value3.
Thanks!
