Pro plan. Prospeo works through a connection and HTTP steps, which are part of Pro and Agency (and the free trial). Anything you already have keeps working on every plan. See Plans and billing.
When someone accepts your invitation, a Webhook / HTTP step sends their LinkedIn profile URL to Prospeo and gets back a verified work email (and a mobile number if you ask). Your email steps, sequencer or CRM can then use it.
How it connects: Prospeo’s API with your API key in a header. See Prospeo’s Enrich Person docs. The request and answer below follow Prospeo’s docs.

​
Before you start

  • Prospeo plan: each email or mobile found uses Prospeo credits, and the API uses the same credits as the app. A mobile costs more than an email (Prospeo’s docs).
  • An API key: in Prospeo, copy it from the API section of your dashboard.

​
1. Connect Prospeo

In Kerux, open Integrations > Connections, click Connect on Custom API (under Developers):
  • How it signs in: API key in a header, Header name X-KEY, paste the key.
  • Base URL: https://api.prospeo.io
Click Save, then Test connection.

​
2. Look up the email

After Invitation accepted, add a Webhook / HTTP step, pick the Prospeo connection, name it prospeo and paste:
Values you type in the JSON (like true) keep their type; values that come from {{...}} are sent as text. Prospeo answers with the person it found (from its docs, trimmed). Pick the exact field paths from the first real answer in the contact’s journey:

​
3. Use it safely

  • Add a Condition on the email field: found goes on to your email step, empty stays on LinkedIn only. Kerux never sends an email to an empty address.
  • Add an Update contact step that sets Email to the email from Prospeo’s answer.
  • To ask for a mobile too, add "enrich_mobile": true only where you will call or text.

​
Test with one contact

In the campaign’s Builder, click Test to open Test on one contact with a contact whose profile you know. The journey shows what Kerux sent to Prospeo and Prospeo’s answer.

​
Common errors

The key is wrong or was regenerated. Copy it again from Prospeo, edit the connection and paste it.
Prospeo found nobody or no verified email for that profile. The step still succeeds; branch on the email being empty.
Your Prospeo credits ran out. The contact stops in Needs attention with Prospeo’s message; add credits and click Retry.
