Handling Telegram Events

Handling Text Events

The most common event that your bot would ever receive is text message. To determine whether the event is a text message event, you may use context.event.isText boolean value to do that:

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

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

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

Handling Payload Events

Payload events can be triggered by keyboards. To determine whether the event is a payload event, you may use context.event.isPayload boolean value to do that:

async function App(context) {
if (context.event.isPayload) {
// handling the payload event
}
}

You can get the payload content using context.event.payload and use it in the reply:

async function App(context) {
if (context.event.isPayload) {
await context.sendText(`received the payload: ${context.event.payload}`);
}
}
