I need to automatically receive new or updated leads/messages to a webhook URL, without polling or manual refresh.
Does your platform send webhook notifications instantly whenever a new lead or message arrives, or is it necessary to regularly query your API to check for updates?
If available, please provide details about how webhooks can be configured (e.g., per account, per channel, or global settings), what kind of events are supported, and whether message contents are included in the webhook payload.

Thank you!
