Onoff Business × Zapier Integration Guide

The Onoff Business × Zapier integration helps you automate workflows by connecting Onoff events, calls, SMS, and voicemails, to hundreds of tools like Google Sheets, Slack, Airtable, Trello, or internal systems. Instead of manually logging calls or creating contacts, Zapier allows you to trigger actions automatically based on mobile activity.

The integration is available on Onoff Business Advanced and Max plans.

Overview: What the Zapier Integration Does

Zapier allows you to:

Trigger automations when calls, SMS, or voicemails occur in Onoff
Send Onoff data to other apps automatically
Create or search contacts in Onoff from Zapier
Send SMS messages from Zapier (following standard Onoff rules)

Important: Unlike CRM integrations, Zapier does not store logs, it passes data into the apps you connect.

Example Use Cases:

Log every outgoing call into a Google Sheet
Send a Slack notification when a voicemail arrives
Update a CRM field when a call is answered
Create a contact in Onoff from another platform
Send an automated follow-up SMS after a call

Connecting Onoff Business to Zapier

Understanding Zapier Triggers (Onoff → Zapier)

A trigger starts a Zap whenever an event occurs in Onoff. Onoff offers five triggers:

New Incoming Call (Instant) – Fires after the call ends
New Outgoing Call (Instant) – Fires after the call ends
New SMS Is Received (Instant) – Fires immediately when an SMS arrives
New SMS Is Sent (Instant) – Fires immediately when an SMS is sent
New Voicemail (Instant) – Fires when a voicemail is received

Data Included in Each Trigger:

Calls (Incoming, Outgoing, Voicemail):

Caller number
Callee number
Timestamp (date/time of the event)
Call duration
Call notes saved during the call
Call tags at the time the call ended
Voicemail link, if applicable

Important : Updates to notes or tags made after the call are not sent.

SMS (Sent / Received):

Sender number
Recipient number
Timestamp
SMS body content

Note: Only the final state of the call or SMS is sent to Zapier, no intermediate updates are transmitted.

Understanding Zapier Actions (Zapier → Onoff)

An action is what Zapier performs inside Onoff. Onoff offers three actions:

Create Contact

Required: Phone number
Optional: First name, last name, email, company
Use cases:
Capture leads from forms or other platforms
Push CRM or spreadsheet contacts into Onoff
Automatically save numbers that text or call

Send SMS

Required: Sender number (must choose one specific Onoff number)
Target number (recipient)
SMS content
Use cases:
Automated follow-ups
Appointment confirmations
Internal notifications

Important : Not meant for bulk messaging.

Search Contacts

Search by phone number (recommended) or name
Configure behavior for:
No match found → continue Zap or stop
Multiple matches → select handling method
Often paired with Create Contact: Search → If not found → Create Contact

Example: Setting Up a Zap with “New Outgoing Call”

This example shows how to create a Zap that sends outgoing call data to Google Sheets. The same setup works for all other triggers as well.

Choose Onoff Business as Trigger App

In Zapier, click Create Zap → Search for Onoff Business → Select

Select Trigger Event

Choose New Outgoing Call → Continue

Connect Your Onoff Account

Copy your API key from Onoff → Paste into Zapier → Connect

Select Users

Choose which Onoff numbers should trigger the Zap
Multiple users can be selected

Test the Trigger

Confirm Zapier receives event data

Choose Action App

Example: Google Sheets → Action: Create Row

Map Onoff Data

Assign fields like caller number, call duration, date/time, user, etc., to columns

Test and Publish

Click Test & Continue → Publish → Make a test call to verify automation

Removing the Zapier Integration

Open Integrations & API on the main page → Zapier in Onoff
Click Remove (red button)
Your API key is deleted; all Zaps relying on it stop working
A new API key can be generated at any time to restore functionality

Best Practices :

Use triggers for real-time automation of calls, SMS, and voicemails
Map all relevant fields when sending data to other apps
Ensure phone numbers are accurate to avoid duplicate contacts
Rotate API keys periodically for security
Always test Zaps before publishing to confirm correct behavior

With this integration, your team can automate workflows, save time, and ensure consistent, accurate data flow across all connected apps.
