An SMS API lets your own software send messages automatically — order alerts, OTPs, reminders and more. Here is how to integrate one using Pak Sender.
Get Your API Key
Create a Pak Sender account and generate an API key from the dashboard. This key authenticates your requests, so keep it secret and never expose it in client-side code.
Send Your First Message
Make a POST request with the recipient number, your message, and your API key. The response confirms the message was accepted. The docs provide copy-paste examples in cURL, PHP, Python, Node.js, Ruby and more.
Handle Responses and Errors
- Check the status in the response for success or failure.
- Log the message ID for tracking and delivery reports.
- Handle common errors like low balance or invalid numbers gracefully.
Test Before You Ship
Use the built-in API Tester to run live requests and see exactly what each endpoint returns — no coding needed to validate your setup.
Go Beyond SMS
The same Pak Sender API also handles Voice OTP, WhatsApp, email and invoices, so you can add new channels later without switching providers.
