How to run shell commands - without api_password

Hello

I’m new to HA and trying to learn how to send bash commands from an RPi.
I have followed this tutorial: https://atwing.net/home%20automation/shell-commands-assistant/

Everything works as it should, until I get to "STEP 3: LINK THE GOOD, THE BAD AND THE UGLY"

How should my IFTTT URL look like without api_password?
Wich token should I use in the URL, IFTTT or HA?
Is there something else in the tutorial that has expired?

Thanks!

Thanks for that link, now atleast that step is confirmed.

Though some questions still remains. I want to create a trigger accordning to this URL:

http://<Raspberry-Pi-IP>:8123/api/services/shell_command/<command_name>?api_password=<your-password>

But instead of using a api_password wich is outdated, I wanna include a token.
How should my URL look like? Wich token should I use, IFTTT or HA?
