Register a webhook for activity events
with lemlist · Webhook & Event Subscription Management
Works with AI assistants
Use lemlist: its Lemlist Webhooks API lets you register a webhook for activity events in a single step (POST /hooks). lemlist also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.
- How do I get notified at my URL when a lead replies or opens an email?
- Can I restrict a webhook to one campaign or only the first occurrence of an event?
Say it to your AI assistant
- Add a webhook that fires only for campaign {campaignId}.
- Create a webhook with isFirst {isFirst} so it triggers only on the first occurrence.
- Register a webhook linked to Zap {zapId}.
For your developer
