How to Send SMS Using PowerShell and an SMS Gateway

Why use PowerShell with an SMS gateway?

Integrating SMS functionality into your PowerShell scripts enables IT professionals, developers, and businesses to automate real-time notifications, alerts, and two-factor authentication (2FA). This approach is ideal for server monitoring, scheduled updates, and responsive system alerts—key for teams in Europe who want simple, reliable communication directly from scripts or servers.

How does an SMS gateway work with PowerShell?

An SMS gateway converts API calls into text messages delivered to global mobile networks. PowerShell can make HTTP requests to the gateway’s API endpoint, creating a powerful bridge between your internal processes and mobile messaging. With Smstools’ robust sms software and API platform, connecting PowerShell and SMS is fast and secure.

Step by step: Sending an SMS with PowerShell

• Step 1. Get your SMS gateway API credentials: Start a free trial to access your unique API key and credentials.
• Step 2. Write a PowerShell script: Use the built-in 'Invoke-RestMethod' or 'Invoke-WebRequest' cmdlets to send data to the SMS API.
• Step 3. Set message parameters: Define sender identification, recipient number, and message content.
• Step 4. Execute and monitor: Send the script manually or embed in server automation or alerting policies.

Example PowerShell script

# Send an SMS via SMS gateway API
$uri = 'https://api.smstools.com/v1/sms/send'
$headers = @{ 'Authorization' = 'Bearer YOUR_API_KEY' }
$body = @{ to = '+44123456789'; message = 'Your alert message here.' }

$response = Invoke-RestMethod -Uri $uri -Headers $headers -Method Post -Body $body
Write-Host $response.status
