@@SmartHomeMakers I think it was because you jumped into using the iPhone so quickly. I only use Android/PC. What would happen if you simply pasted the whole URL into a web browser?
I have a piece of software that can post data to a generic endpoint. I believe t is a json data. Knowing nothing about json, how can I get help picking out the values that matter to me?
So as i understand it, when you send the json with the key and data , you reference the key name in home assistant. Something like data: message: "{{ trigger.json.message }}" With message being the key in the json.
