Pak Sender API Reference

The Pak Sender API lets your own software send messages automatically — order alerts, OTPs, reminders and more — through one clean REST interface.

One API, Every Channel

Send SMS, Voice OTP, WhatsApp and email, create invoices, and manage auto-billing — all with the same API key and a consistent request format.

Simple to Use

• Generate your API key from the dashboard.
• Make a POST request with the recipient and your message.
• Read the response for status and message ID.
• Track delivery through reports.

Examples in Every Language

The reference includes ready-to-copy snippets in cURL, PHP, Python, Node.js, Ruby and more, so you can integrate in minutes.

Test Before You Ship
