hi
@Leon Kozlowski - good question
i think the short answer is that its a bit tricky unless you already have a webapp like
this
because afaik, (unlike github webhooks) slack needs a response right away (within 3 seconds) and our webhooks system doesn't currently send a response to the sender like that (though that potentially could change)
if you have a webapp in the picture then you can simply background the work and send the response that slack needs
does that answer your question?
