How to get the result of what user clicked in interactive buttons ? about java-slack-sdk HOT 6 CLOSED

Button clicks are not slack events - they are not provided by the RTM API.

Button clicks require a callback handler /URL which is out of scope for this library.

Please see the 'Responding to message actions' section of the doc: https://api.slack.com/docs/message-buttons

Thanks for fast response
Will this option be someday in this library?

I can't see that ever happening personally. It's out of scope because it isn't really something that can be included in a library. It would require a web server to receive the callbacks and each application has a different requirement for handling the button clicks.

Having said that, I don't run the project :) @seratch ?

Right, I don't have any plans to do something.

After 1.5 years, I've implemented some features to easily build a Slack App backend to handle the scenario discussed here. Actually, it's not possible to receive the event as an RTM events, but we can receive interactive messages on our side side.

Check the classes under this package. I've already started using these classes for my personal Slack apps.

For example, let's say a user clicks a button in a message made of BlockKit components. At the time, your Slack App backend receives a HTTP request from Slack Platform. The request body contains a payload which has the type block_actions as below. You can use this class to bind the request body. Here is a simple example code.

Please allow me close this issue. Feel free to reopen this when you have something to discuss further here at any time.
