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

LinkedIn replies into ActiveCampaign

Q: Does a second sync create a duplicate?

No. contact/sync finds the contact by email and updates it, so it's safe to run again.

Q: How do I fill custom fields?

Send fieldValues with the field's numeric id and the value, as ActiveCampaign's docs describe. The field ids are in ActiveCampaign's fields list.

When a lead replies on LinkedIn, a follow-up campaign syncs them into ActiveCampaign with their name, email and phone, and your ActiveCampaign automation starts the email side.

An example workflow

LinkedIn invitation and two messages.
The lead replies: the When the lead replies box sends them to a follow-up campaign with Send to another campaign.
A Webhook / HTTP step POSTs to ActiveCampaign's contact/sync with email, firstName, lastName and phone.
A second step adds a tag with the contact id from the first answer.
Your ActiveCampaign automation, started by the tag, sends the email follow-up.

contact.id

Set it up

In ActiveCampaign, open Settings > Developer and copy your API URL and key. Kerux sends the key in the Api-Token header.
In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how ActiveCampaign signs in, paste the key and ActiveCampaign's Base URL, click Save, then Test connection.
Use your API URL as the Base URL (it looks like https://youraccount.api-us1.com).
Add a Webhook / HTTP step: POST /api/3/contact/sync with {"contact": {"email": ..., "firstName": ..., "lastName": ...}}. The id is {{steps.<step>.response.body.contact.id}}.
In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to ActiveCampaign and what came back.

Plan limits: ActiveCampaign's API is available on all its plans; automations depend on the plan (ActiveCampaign's docs and pricing).

Questions

Does Kerux have a native ActiveCampaign integration?

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

Does a second sync create a duplicate?

No. contact/sync finds the contact by email and updates it, so it's safe to run again.

How do I fill custom fields?

Send fieldValues with the field's numeric id and the value, as ActiveCampaign's docs describe. The field ids are in ActiveCampaign's fields list.

What happens if ActiveCampaign is down or refuses a call?

The lead stops with ActiveCampaign'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.
