Via API steps and webhooks No app to install: Kerux talks to Hunter's API with HTTP steps and webhooks, set up once.

Hunter fills in the email for LinkedIn leads

A GET step asks Hunter's Email Finder for the lead's address using their name and company domain. Kerux reads the email, Hunter's score and its verification status before any email goes out.

How it works

Sofia is in the campaign
Name and company site, but no email yet.
Hunter finds the address
With a score and a verification status.
Email only when it's safe
Low scores stay on LinkedIn.

An example workflow

Enroll leads with first name, last name and company website.
A Webhook / HTTP step GETs Hunter's Email Finder with domain, first_name and last_name.
A Condition keeps only answers with a good score and the status valid.
An Update lead step saves the email on the lead.
LinkedIn invitation first, then an email a few days later if there's no answer.

What data flows

Kerux sends to Hunter

lead.first_name
lead.last_name
company.website

Hunter sends to Kerux

data.email
data.score
data.verification.status

Set it up

In Hunter, copy your API key from API in your account. Kerux adds it to the URL as api_key.
In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how Hunter signs in, paste the key and Hunter's Base URL, click Save, then Test connection.
Add a Webhook / HTTP step: GET /v2/email-finder with the query domain, first_name and last_name (or linkedin_handle).
Branch on data.score and data.verification.status, and save data.email on the lead.
In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to Hunter and what came back.

Plan limits: Hunter has a free plan with a small monthly number of searches; paid plans add more (Hunter's pricing).

Questions

Does Kerux have a native Hunter integration?

Not a one-click app. Kerux works with Hunter today through Hunter's own API: you save your Hunter key once in Kerux, then HTTP steps and webhooks do the work inside your campaigns. Nothing to install and no Zapier needed.

What does Hunter's score mean?

It's Hunter's confidence that the address is right, from 0 to 100. Pick a threshold in the Condition; anything below stays on LinkedIn.

Does a search with no result use credits?

Hunter's docs say Email Finder only counts a request when it returns an email.

What happens if Hunter is down or refuses a call?

The lead stops with Hunter'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.
