FullEnrich waterfall enrichment inside a LinkedIn campaign

Q: Can I ask only for emails to save credits?

Yes. enrich_fields picks what to look for: work emails, personal emails, phones or a mix. Phones cost more credits than emails (FullEnrich's docs).

A Call & wait step sends the lead to FullEnrich with a per-lead callback URL. FullEnrich checks its providers one after another, calls back with the result, and the lead moves on.

How it works

Call & wait: FullEnrich
```
POST /contact/enrich/bulk
{
  "linkedin_url": "...",
  "webhook_url": "{{wait.callback_url}}"
}
```
Waiting for the result
Kerux starts the job
With a callback URL just for this lead.
Sofia's details arrive
FullEnrich calls back when the waterfall ends.
Your rep is told
With the phone number, ready for a call.

An example workflow

Send the LinkedIn invitation.
Accepted: a Call & wait step POSTs the lead to FullEnrich's bulk enrich endpoint with webhook_url set to {{wait.callback_url}}.
The lead waits (for example up to 2 hours) until FullEnrich calls back with the result.
A Condition on the result: an email found goes to your email step; a phone found posts to Slack for a call.
Timed out: the lead keeps going on LinkedIn only.

What data flows

Kerux sends to FullEnrich

lead.first_name
lead.last_name

FullEnrich sends to Kerux

The enrichment result FullEnrich sends to the callback URL: emails and phones it found.

Set it up

In FullEnrich, create an API key in the app's settings. Kerux sends it as a bearer token.
In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how FullEnrich signs in, paste the key and FullEnrich's Base URL, click Save, then Test connection.
Add a Call & wait step: POST /api/v2/contact/enrich/bulk with name, webhook_url: {{wait.callback_url}} and one item in data (first_name, last_name, company_name, linkedin_url and enrich_fields).
Click Listen for test event, run one lead, and pick the email and phone fields from what FullEnrich sends back.
In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to FullEnrich and what came back.

Plan limits: FullEnrich bills credits per email or phone found, and nothing when nothing is found (FullEnrich's pricing).

Questions

Does Kerux have a native FullEnrich integration?

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

Why does the lead wait instead of getting the email right away?

FullEnrich runs its waterfall in the background and reports when it's done. The per-lead callback URL means the answer always lands on the right lead.

Can I ask only for emails to save credits?

Yes. enrich_fields picks what to look for: work emails, personal emails, phones or a mix. Phones cost more credits than emails (FullEnrich's docs).

What happens if FullEnrich is down or refuses a call?

The lead stops with FullEnrich'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.
