Your calls, in your own system.
For businesses with a developer or their own software: each event as it happens, signed, with a stable ID.
Free for 3 days with up to 10 answered calls. No card.
Nerro's outgoing webhook sends a signed HTTP request to your URL when something happens: a call ends, a call is missed, a lead isn't reached, an appointment is booked or changed, or an order is placed. You pick the events. Each request carries an x-nerro-signature header over the timestamp and raw body, and a stable event ID, so you can check it came from Nerro and skip repeats.
How it works.
Add a URL on the Connectors page and choose events.
- Pick your events
- Call ended, call missed, lead not reached, appointment booked or changed, order placed.
- Check the signature
- An HMAC of the timestamp and raw body with your secret, in x-nerro-signature.
- Skip repeats
- A repeated delivery carries the same event ID.
- Only confirmed data
- Built from what happened on the call, never from what the AI said it would do.
- Send a test
- Fire a test event to check your endpoint before real calls.
- Plus an API
- Read your data with an API key; see the developer page.
When no-code is easier.
Where the other option is the better choice.
- No developer on hand: Zapier connects the same calls to thousands of apps.
- You only want to know about calls: Slack or email alerts.
Questions, answered.
Something else? Ask us.
Which events can I receive?
call.ended, call.missed, lead.not_reached, appointment.booked, appointment.changed and order.placed.
How do I check a request is from Nerro?
Compute an HMAC with your webhook secret over the timestamp, a dot and the raw body, and compare it with x-nerro-signature.
Are failed deliveries retried?
Yes, with the same event ID, so you can ignore repeats.
What is in a call.ended payload?
The event ID, call ID, AI employee, outcome, summary, start time and caller number.
Can I have more than one webhook?
Yes: one for the business, and one on each AI employee if you want its calls sent somewhere else.
Can I test my endpoint?
Yes. Send a test event from Connectors.
Is there an API too?
Yes. Read your calls and leads with an API key; see the developer page.
Webhook requests contain caller phone numbers and call summaries. Use an HTTPS endpoint and keep your secret private.
