LinkedIn outreach for your HighLevel workflows

A reply on LinkedIn updates the contact in HighLevel and adds a tag that starts your workflow. HighLevel can also send contacts into a Kerux campaign, and a booked appointment stops the follow-ups.

An example workflow

A HighLevel workflow sends new contacts that have a LinkedIn URL to a Kerux trigger URL with its Custom Webhook action.
Kerux sends the LinkedIn invitation and messages.
The lead replies: the When the lead replies box sends them to a short follow-up campaign, where a Webhook / HTTP step upserts the contact in HighLevel and adds the linkedin-replied tag.
The tag starts your HighLevel workflow: SMS, email, pipeline stage.
An Appointment Booked workflow posts to Kerux's booking URL, and the remaining LinkedIn steps stop.

Set it up

In HighLevel, open Settings > Private Integrations in the sub-account, create one with the contacts scopes and copy the token. Kerux sends it as a bearer token.
In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how HighLevel signs in, paste the key and HighLevel'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 /contacts/upsert on services.leadconnectorhq.com with locationId, email, name and tags. Add the Version header HighLevel's docs ask for.
To send contacts into Kerux, add a Custom Webhook action in a HighLevel workflow: POST to the campaign's trigger URL with a JSON body of linkedin_url, first_name, email.
For bookings, add a booking tool in Kerux (Another booking tool) and post to its URL from an Appointment Booked workflow.
In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to HighLevel and what came back.

Questions

Does Kerux have a native HighLevel integration?

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

Does this work for each client account?

Yes. Private Integration tokens belong to a sub-account (location), so each client gets its own token and its own Kerux connection.

Can HighLevel send a booking without a LinkedIn URL?

Yes. Booking webhooks find the lead by email, so the contact's email is enough to stop the follow-ups.

What happens if HighLevel is down or refuses a call?

The lead stops with HighLevel'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.
