Hi.
I'll try webhooks. Ya I know the thread is old but the content is relevant. I too am not seeing any response string from pushingbox. It works for the actions though, so once-sided "GET" is ok. Do you have the code for the bare bones http client that you setup?
Sorry for the late reply been crazy busy with work…
I haven’t got the full code saved anywhere but if you search through my forum posts from the last couple of years you may find what you need.
There was a post about a php script that I ran on my web server, that I called with just the standard GET same as the pushing box one, it just returned a random string from the server, that got displayed on a message torch.
