API Trouble - Unknown Variable: false

[lv328r]

I have a Photon with two functions that I’m trying to call from a webpage.

motionUp & motionDown

My API string looks like this (data replaced to protect the innocent)

When I paste that in a browser I get a “Unknown Variable: false” error
Using the Particle Console the function work just fine.
Not sure what the issue could be.

Tutorial: Spark Variable and Function on One Web Page

Let’s say you have a Spark core with both a Spark variable and a Spark function. In my case, I have the world’s simplest servo control sketch, using the nice miniature servo in the Spark Maker Kit. Using these parts, we will build a servo that you can control from a web page anywhere and monitor the position of the servo too! Here’s a preview of the finished tutorial: [image] There is a coarse adjust slider, two fine adjust buttons, and the current position of the servo is displayed. That…
