Form Android Widget to Node Red input

Hello from Germany.

I have a little issue and I dont know hoe to get around this problem.

I want a simple input, not even data but just a trigger msg within Node Red, which is triggert when I press a Widget on the homescreen of my android phone.

I thought about HTTP requests, but couldnt get exactly how they are supposed to work.

Hopefully someone here will have a hint in the right direction.

Set the http in node up with path /trigger
select post or get
then use the url http://ip_of_node-red:1880/trigger send via post/get depending which your widget app will allow.
You may wish to add the http respose node after the in node.
