However, IFTTT trigger the Orb but returning timed out error. After discussing with Zhenfang I tested with the setColor function to check my settings for IFTTT and it actually works. So the question may be resulted from calling and waiting for return in the ambientOrb function that takes longs than the maximum website server waiting time. So the change needed is to remove the call and response outside of the particle function that works with web hook, replaced with a bool that serve as a flag to trigger the fade functions.
