Variable (current source) in HTTPRequest

Is it possible to add the source on which the motion occurred to a HTTPRequest URL when setting up a rule? This would be quite handy as it would allow services like IFTTT to recognize which of the sources was triggered, otherwise I’d have to copy/set-up the rule multiple times.

Yes, that would be nice. I suspect that the name of the parameter is already in the system, but I do not have that. Maybe it can be figured out from the WebAPI. I will ask for this also.

any news or info around this?
