How to Track Chat Labels via Webhook

How can I detect which label is assigned to a chat using webhooks?

The simplest and most efficient way is to enable the chats.patch webhook event. This webhook notifies you whenever there's a change to a chat — including when a label is added, changed, or removed.

The chats.patch payload contains the current label assigned to the chat, so you can always stay updated without making additional API calls.

This is especially useful if you want to keep track of labels without querying the HTTP API manually. Using the webhook is lighter, real-time, and fully automated.
