Webhooks let you receive real-time POST callbacks whenever specific events occur in your lemlist workspace. You can subscribe to individual activity events (e.g. emailsOpened, linkedinReplied, whatsappMessageSent) or to lead-state groups (e.g. contacted, warmed, interested) that aggregate multiple activity types. For the full categorized list of available events, see Add Webhook.

Webhooks send real-time HTTP notifications upon campaign events (opens, clicks, replies, etc.).
