Do you have token=(your token from Instructions page) in the body?

https://www.triggercmd.com/api/IFTTT?trigger=Notepad&computer=PC
method = POST
Content-Type: application/x-www-form-urlencoded

with PC being the name of my computer as registered in my profile.

https://www.triggercmd.com/api/IFTTT?trigger=ispy&computer=MyPC&params=recordstop.alarmset

Then make a command with these values:

• Trigger = ispy
• Command = c:\program files\ispy\ispy.exe (probably a different path)
• Allow Parameters = true

 Create 2 tasks conditions in IFTTT, for “Off” & “On”.
 Use <if><gmail> with proper filter on sender and subject), using respectively the words”Disarmed” & “Armed”.
 Use your method to trigger a batch commands to iSpy, that may look like this:
URL: https://www.triggercmd.com/api/IFTTT?trigger=run ispy.exe "recordstop.alarmset"&computer=MyPC
... where alarmset is the set of cameras to stop in this case.
I will keep you posted of the outcome.

In brief, to reboot/restart your Windows 10 PC from an iOS Home Screen button click, do the following:

1. Install TriggerCMD Agent
2. Sign up/in to IFTTT
3. For the If bit: select Button Widget
4. For the Then bit: select webhooks and enter the following:
   i. URL: https://www.triggercmd.com/api/IFTTT?trigger=Reboot in 10 seconds&computer=R1
   ii. METHOD: POST
   iii. CONTENT TYPE: x-www-form-urlencoded
   iv. BODY: token=XYZ

Notes:
There are spaces in "Reboot in 10 seconds"
My computer name is "R1"
<obviously <XYZ> is my token

To add the button widget to your iOS home screen:

1. Tap the share icon (square with the up arrow)
2. Tap "Add to Home Screen"
3. Tap "Add"
4. Enjoy

URL: https://www.triggercmd.com/api/IFTTT?trigger=Reboot in 10 seconds&computer=R1
BODY: token=XYZ

Am super-lovin' this

However, and trying to configure an IFTTT Button Widget to kick-off a webhook to my PC (PC name R1) to run the Reboot in 10 seconds command, but keep getting 401 errors - please help.

Am at the webhooks config page in IFTTT and entering the following:

URL: https://www.triggercmd.com/api/IFTTT?trigger=reboot&computer=R1
METHOD: POST
CONTENT TYPE: x-www-form-urlencoded
BODY: token=XYZ&params=russ.txt

<obviously <XYZ> is my token

What am I doing wrong please ?

Thanks so much,

Dan

Method: POST
Content type: x-www-form-urlencoded
Body: token=(your token)

One problem I've had before was I had a space in the body field that I didn't notice. That could cause that error.

You have:
https://www.triggercmd.com/api/IFTTT?trigger=spotify

But you need:
https://www.triggercmd.com/api/IFTTT?trigger=spotify&computer=YourComputerName

If I want to run a trigger from IFTTT, for example, a trigger called "spotify" (which works when I trigger it from the web page manually), I then use this for the URL:

https://www.triggercmd.com/api/IFTTT?trigger=spotify

and then later in the IFTTT webhook I set the body to:

token=sdfhksdhfjkasdhfajksdfhajkhf.......... (whatever it is for my computer)
