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

Apollo emails for your LinkedIn leads

When a lead accepts your invitation, an API step asks Apollo for their work email. No reply on LinkedIn? Add them to an Apollo sequence.

How it works

Maria connects
Your invitation is accepted.
Apollo finds her email
People Match by LinkedIn URL.
Email takes over
No reply after a week: she joins your Apollo sequence.

An example workflow

LinkedIn invitation; when it's accepted, a Webhook / HTTP step calls Apollo's people match with {{lead.linkedin_url}}.
The email Apollo returns, {{steps.apollo.response.body.person.email}}, is used by the next steps.
Send the LinkedIn message and wait 7 days.
No reply: a second step adds the contact to an Apollo sequence.

What data flows

Kerux sends to Apollo.io

lead.linkedin_url
lead.first_name
lead.last_name
lead.company

Apollo.io sends to Kerux

person.email
person.title
person.organization.name

Set it up

In Apollo, open Settings > Integrations > API and create an API key. Kerux sends it in the x-api-key header.
In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how Apollo.io signs in, paste the key and Apollo.io's Base URL, click Save, then Test connection.
Add a Webhook / HTTP step after the invitation is accepted that POSTs to Apollo's people match endpoint with linkedin_url, first_name and last_name.
To use a sequence, add a step that adds the contact to it. Apollo's docs say which endpoints need a master API key.
In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to Apollo.io and what came back.

Plan limits: Access to Apollo's API depends on your Apollo plan (Apollo's API docs), and each endpoint has its own rate limit shown in Apollo.

Questions

Does Kerux have a native Apollo.io integration?

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

Does each lookup use Apollo credits?

Yes, revealing an email uses Apollo credits from your plan. Kerux calls Apollo once per lead at that step, never again for the same lead.

What if Apollo finds no email?

The step's answer has no email, so a branch can keep that lead on LinkedIn only. Kerux never sends an email with an empty address.

What happens if Apollo.io is down or refuses a call?

The lead stops with Apollo.io'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.
