ListKit doesn't have a public API yet. It's in development. Today you can send events to your CRM, an automation tool or your own app with webhooks.
TL;DR
ListKit doesn't have a public API yet. It's in development.
Webhooks send ListKit events, like a lead's category changing or a lead replying, to any HTTPS URL. Set them up on the Integrations page in the sidebar.
You can import contacts from HubSpot to enrich them in Enrichment.
The Zapier app and API key, Google Drive, Google Sheets, Smartlead and Workflows integrations are no longer available.
When you'd use this
Use this to connect ListKit to the other tools you use, for example to send every positive reply to your CRM.
Webhooks
A webhook sends an event from ListKit to a URL you choose the moment it happens. Any tool that gives you a webhook URL works: your CRM, Make, GoHighLevel, Zapier or your own app. Each webhook can cover all campaigns or one campaign.
Open the Integrations page from the sidebar to add and manage webhooks. For the full setup, see How do I send ListKit events to my CRM or other tools with webhooks?
HubSpot import
You can bring contacts in from HubSpot when you enrich a list in Enrichment. See How do I use the Enrichment Tool to enrich a lead list?
Grok Bot (community workflow)
Some customers use Grok Bot, a third-party AI agent, to work their Master Inbox. It's community-built and not supported by ListKit. See How do I automate my ListKit inbox with Grok Bot?
Getting leads into campaigns
You don't need an integration to load leads into a campaign. Add leads from Order History when you set up a campaign. See How do I create a campaign in Email Engine?
No longer available

Expected outcome
You know what ListKit connects to today, and you can send ListKit events to your other tools with webhooks.
FAQ
Does ListKit have an API?
Not yet. A public API is in development. Today you can send events to other tools with webhooks.
Is there a ListKit MCP or Claude integration?
Not yet. It's in development.
Can ListKit push interested leads with their reply into my CRM?
Yes, with webhooks. Send reply and lead category events to your CRM or automation tool, and keep only Interested or Meeting Booked leads with a filter on your side.
Does ListKit work with Zapier, Make or GoHighLevel?
Yes, through webhooks. Create a webhook URL in that tool (in Zapier, a Catch Hook) and add it to a ListKit webhook. ListKit doesn't have its own Zapier app.
My webhook stopped delivering. What should I check?
Make sure the URL starts with https and that your endpoint accepts the request. Send a test from ListKit. If a webhook keeps failing, it's paused and the account owner gets an email. Missed events aren't sent again. Edit and save the webhook to turn it back on.
Is there a mobile app?
No. ListKit runs in your web browser.
Does ListKit do LinkedIn outreach?
No. ListKit sends cold email. Personal LinkedIn URLs are included in exports when available.
