Via API steps and webhooks No app to install: Kerux talks to Close's API with HTTP steps and webhooks, set up once.
LinkedIn replies straight into Close
When someone replies on LinkedIn, an API step creates the lead and its contact in Close, ready for a call. When the status changes in Close, Kerux follows.

Close moves, Kerux follows
Status Qualified: LinkedIn follow-ups stop.
An example workflow
- LinkedIn invitation and two messages.
- Reply: the When the lead replies box sends them to a short follow-up campaign, where a Webhook / HTTP step creates the Close lead with a contact (name, email, LinkedIn URL).
- The rep calls from Close and changes the status.
- Close's webhook reaches a Kerux Wait for webhook step, matched by email.
- Qualified: no more LinkedIn follow-ups. Not interested: tag and end.

Set it up
- In Close, open Settings > Developer > API Keys and create a key. Kerux uses it with basic auth (the key as user name, no password).
- In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how Close signs in, paste the key and Close's Base URL, click Save, then Test connection.
- In the follow-up campaign the When the lead replies box sends leads to (Send to another campaign), add a Webhook / HTTP step that POSTs to
/api/v1/lead/with the company name and a contact (name, email, LinkedIn URL). - For status changes, subscribe a Close webhook to lead updates (Close's docs show the call) pointing to a Kerux Wait for webhook step's shared URL.
- In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to Close and what came back.
Questions
Does Kerux have a native Close integration?
Not a one-click app. Kerux works with Close today through Close's own API: you save your Close key once in Kerux, then HTTP steps and webhooks do the work inside your campaigns. Nothing to install and no Zapier needed.
Can Close start a LinkedIn campaign?
Yes, through Zapier, Make or n8n: a new lead or a Smart View change sends the contact's LinkedIn URL to a Kerux trigger URL.
What happens if Close is down or refuses a call?
The lead stops with Close's own error message and shows in Need attention with a Retry button. It never shows as finished because a call failed, and nothing else goes out to that lead until you decide.
