The Zapier integration connects Onoff to hundreds of tools (Google Sheets, Slack, Airtable, Trello…). A call, SMS or voicemail can trigger an automatic action, and Zapier can create contacts or send SMS in Onoff. Zapier doesn't store data: it passes it to the connected tools.
Plan: Advanced or Max. Role: Owner or Admin.
Use cases
- Add each outgoing call to a Google Sheets spreadsheet.
- Get a Slack notification for each new voicemail.
- Create an Onoff contact from a form.
- Send an automatic follow-up SMS after a call.
Get the API key
- In the console, open Integrations & API > Zapier.
- Click Get API Key and copy the key.
Renew API Key generates a new key: the old one stops working immediately, and your Zaps stop until you paste the new key into Zapier.
Triggers (Onoff → Zapier)
| Trigger | When | Data sent |
|---|---|---|
| New Incoming Call / New Outgoing Call | When the call ends | Caller and callee numbers, date and time, duration, notes and tags saved during the call |
| New Voicemail | When the voicemail is received | Same data, plus the voicemail link |
| New SMS Is Received / New SMS Is Sent | Immediately | Sender and recipient numbers, date and time, message text |
Notes and tags changed after the call aren't sent. Times follow the time zone in the Onoff account settings.
Actions (Zapier → Onoff)
| Action | Fields | Good to know |
|---|---|---|
| Create Contact | Number (required); first name, last name, email, company | Often combined with Search Contacts: search, then create if not found. |
| Send SMS | Sending Onoff number, recipient number, text | For one-off messages (follow-up, appointment confirmation), not bulk sending. |
| Search Contacts | Number (recommended) or name | You choose what happens if no contact or several contacts match. |
