In theory I already know what the function is; you send data to a server and it's different from POST URL.
In practice I have no clue and YouTube, Google didn't offer much info either.
I'd like to try the short press/long press demo out.
Any deliberate examples on how to use the GET URL function with bt.tn?
I suggest you to take look at our API documentation https://my.bt.tn/api/webhooks.
Briefly, you can configure your bttn to trigger either GET or POST HTTP request from the bttn cloud. This request could for example trigger a service request in another backend system -let say place an order to eg. taxi dispatch system.
It's easy to test the functionality using service like Requestbin, instructions how to do that you find in API docs #webhooks
