n8n and Make

n8n and Make don't need a special Nerro app: they talk to the API with their HTTP steps.

Send to Nerro

Add an HTTP Request node (n8n) or an HTTP: Make a request module (Make):

• Method and URL from the API reference, like POST https://www.nerro.co/api/v1/campaigns/CAMPAIGN_ID/contacts.
• Header Authorization with the value Bearer nrz_your_key. In n8n, keep it in a Header Auth credential rather than in the node.
• Body type JSON.

To have a new lead called back within seconds, post it to your lead source URL instead. That needs no key.

Receive from Nerro

1. Add a Webhook trigger (n8n) or a Webhooks: Custom webhook (Make) and copy its URL.
2. In Nerro, open Connectors → Outgoing webhook, paste the URL and press Send test.
3. Every finished call now starts your workflow. See Webhooks for the body and how to check the signature.

Example: hot leads to your sales team

Webhook trigger → keep only calls whose outcome is lead_captured or appointment_booked → look the call up with GET /calls for the captured details → create the deal in your CRM.
