LinkedIn replies as Copper people

When a lead replies, a follow-up campaign creates them in Copper with their email and LinkedIn profile, and your team picks it up in the Google Workspace tools they already use.

Set it up

In Copper, open Settings > Integrations > API Keys and generate a key. Kerux sends it in the X-PW-AccessToken header.
In Kerux, open Integrations > Connections and click Connect on Custom API (under Developers). Pick how Copper signs in, paste the key and Copper's Base URL, click Save, then Test connection.
Copper also needs X-PW-Application: developer_api and X-PW-UserEmail (the email of the key's owner) as headers on the step.
Add a Webhook / HTTP step: POST /developer_api/v1/people with name, emails: [{"email": ..., "category": "work"}] and socials.
In the campaign's Builder, click Test to open Test on one lead: the lead's journey shows what Kerux sent to Copper and what came back.

Plan limits: Check Copper's pricing page for API access on your plan.

Questions

Does Kerux have a native Copper integration?

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

Does Copper check for duplicates?

Not on create. Search Copper's people by email first (Copper's search endpoint) and branch, so a lead who replies twice isn't added twice.

Can I create an opportunity too?

Yes, with a second step to Copper's opportunities endpoint, using the person id from the first answer.

What happens if Copper is down or refuses a call?

The lead stops with Copper'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.
