Set Up an Android SMS Gateway with Zapier in 10 Minutes

Published April 8, 2026 · 5 min read

Zapier connects 7,000+ apps. Pairfon turns your Android phone into an SMS gateway. Put them together and you can send text messages from basically anything: form submissions, CRM updates, Stripe payments, Google Sheet rows, Calendly bookings. All from your real phone number.

This guide walks you through the complete setup. You'll have a working Zap in about 10 minutes.

Prerequisites

A Pairfon account (Growth plan or higher for Zapier integration)
An Android phone paired to your Pairfon dashboard (setup guide)
A Zapier account (free tier works for testing)

What Pairfon's Zapier Integration Offers

Pairfon shows up in Zapier with two components:

Trigger: "New SMS Received" — fires whenever an inbound SMS arrives on your Pairfon device. The trigger payload includes the sender's number, the message body, the device name, the SIM used, and a timestamp.

Action: "Send SMS" — sends an outbound SMS through your Pairfon device. You specify the recipient number, the message body, and which device/SIM to use.

Setup: Connect Pairfon to Zapier

Step 1

Get your Zapier connection link

In your Pairfon dashboard, go to Integrations. Find the Zapier card and click Connect. This generates an invite link that authorizes Pairfon in your Zapier account.

Click the link. Zapier will ask you to accept the Pairfon integration. Confirm it.

Step 2

Create a new Zap

In Zapier, click Create Zap. For the trigger app, search "Pairfon" and select it. Choose New SMS Received as the trigger event (or skip if you only need outbound).

When prompted to connect your account, your Pairfon API key will be pre-filled from the authorization step. Click Continue.

Step 3

Configure the trigger

Select which device should trigger the Zap. If you have multiple devices, pick the one whose inbound messages you want to act on. Click Test Trigger to pull in a sample SMS.

Zapier will show you the sample data: sender number, message body, timestamp, device name, and SIM slot. You'll use these fields in your action steps.

Step 4

Add an action

Now add whatever action you want. Some examples:

Google Sheets: Log every inbound SMS to a spreadsheet
Slack: Post the message to a channel
HubSpot: Create or update a contact based on the sender's number
Email: Forward the SMS to your inbox

Example: Auto-Reply to New Leads

Here's a real workflow. A new lead fills out a form on your website. Zapier catches the form submission and sends an SMS from your phone within seconds.

Zap Configuration

Trigger: Typeform → New Entry

Action: Pairfon → Send SMS

To: {{phone_number}} (from the form submission)

Message: "Hi {{first_name}}, thanks for reaching out. We'll call you within the hour. - {{your_business_name}}"

Device: Your paired Pairfon device

The lead gets a text from your real business number within seconds of submitting the form. When they reply, it shows up in your Pairfon dashboard (and can trigger another Zap if you want).

Example: Appointment Reminder from Google Calendar

Zap Configuration

Trigger: Google Calendar → Event Start (1 hour before)

Filter: Only continue if event description contains a phone number

Action: Pairfon → Send SMS

To: Phone number extracted from event description

Message: "Reminder: Your appointment is in 1 hour. Reply CONFIRM or call us to reschedule."

Example: Log Inbound SMS to Google Sheets

Zap Configuration

Trigger: Pairfon → New SMS Received

Action: Google Sheets → Create Spreadsheet Row

Columns: Date, From Number, Message, Device Name

Every inbound SMS gets logged automatically. Useful for record-keeping, compliance, or building a contact list from text-ins.

Using Webhooks Instead of the Native Integration

If you prefer webhooks over the native Zapier app, Pairfon supports that too. Set up a "Webhooks by Zapier" trigger in your Zap, copy the webhook URL, and paste it in your Pairfon dashboard under API & Webhooks.

The webhook payload looks like this:

{
  "event": "sms.received",
  "from": "+15551234567",
  "to": "+15559876543",
  "body": "When is my appointment?",
  "device": "Office Phone",
  "sim": "SIM 1",
  "timestamp": "2026-04-08T14:30:00Z"
}

For outbound, use a "Webhooks by Zapier" action to POST to Pairfon's REST API:

POST https://web.pairfon.com/api/v1/sms/send
Authorization: Bearer your-api-key
Content-Type: application/json

{
  "to": "+15551234567",
  "body": "Your order has shipped!",
  "deviceId": "your-device-id"
}

Tip: The native Pairfon Zapier app is easier to set up and handles authentication automatically. Use webhooks only if you need the extra flexibility or are on Zapier's free plan (which supports webhooks but limits native app connections).

Troubleshooting

Zap isn't triggering on new SMS: Make sure your device is online in the Pairfon dashboard. Also check that you selected the correct device in the Zapier trigger configuration.

Send SMS action fails: Verify your API key hasn't been rotated. Go to Pairfon dashboard → API & Webhooks to check. If it was regenerated, you'll need to reconnect in Zapier.

Messages are delayed: Zapier polls triggers on an interval (1-15 minutes depending on your Zapier plan). For near-instant triggers, use the webhook method instead of the native trigger.
