Handling Slack Events

Text Events

The most common events are text message events. To determine whether the event is a text message event, you may use the context.event.isText boolean value:

async function App(context) {
  if (context.event.isText) {
    // handling the text message event
  }
}

You can get the text content using context.event.text to use it in the reply:

async function App(context) {
  if (context.event.isText) {
    await context.sendText(`received the text message: ${context.event.text}`);
  }
}
