bt.tn provides two ways for your servers to respond to bttn presses:
The bttn HTTP action lets you configure a webhook URL that the bt.tn server will call whenever the bttn is pressed. The webhook URL can be static or you can use the bt.tn REST API to register a dynamic webhook URL. The bttn HTTP action has support for all the common HTTP methods, formats and options, so making webhook calls to your existing REST API is easy.
The bt.tn REST API lets you read information about bttns and bttn presses. This method suits best non-real time applications that fetch bttn press information on demand. You can choose to use Api-Keys for authenticated REST API access or to publish your bttn data to every bt.tn REST API user.
