Add OTP login, WhatsApp and SMS order notifications, abandoned cart recovery, COD verification and bulk campaigns to WordPress and WooCommerce with the official Fast2SMS plugin.

The plugin is completely free. Bring your own Fast2SMS API key — messages are billed to your own Fast2SMS wallet at your account rates, and delivery reports stay in your own Fast2SMS panel. No monthly fee, no per-site licence.

WooCommerce automations

  • Order placed, payment received, order completed, cancelled, refunded
  • COD order alerts + one-tap COD OTP verification link (reduce RTO)
  • Abandoned cart recovery with configurable delay
  • SMS, WhatsApp, or both per event — pick approved DLT / WhatsApp templates straight from your Fast2SMS account with variable mapping

OTP everywhere

  • Login with OTP on the WooCommerce login form and wp-login.php
  • Phone verification on signup/registration
  • [fast2sms_otp_login] shortcode for any page or Elementor
  • OTP verification on Contact Form 7 ([fast2sms_otp] tag), WPForms and Elementor Pro Forms ([fast2sms_otp_verify])
  • Rate limits built in: per-phone, per-IP, attempt caps and resend cooldown

Bulk campaigns

  • Send an approved template to all customers, all users, or a pasted/CSV list
  • Queue-based sending with automatic retries and full logs

More

  • Wallet balance and SMS count in the dashboard header
  • Admin SMS/WhatsApp alert on form submissions
  • Low-balance email alert
  • Message logs with masked phone numbers
  • Phone numbers and API key encrypted at rest (AES-256-GCM), automatic data retention purge

Works without WooCommerce too — OTP login, form OTP, form alerts and campaigns run on plain WordPress. WooCommerce-only features light up automatically when WooCommerce is installed.

Requirements

  • A free account at fast2sms.com with your own API key
  • For SMS: approved DLT templates in your Fast2SMS panel
  • For WhatsApp: approved WhatsApp templates in your Fast2SMS panel
  • For OTP: an OTP ID created in your Fast2SMS panel (Smart OTP section)
  • Target market: India (10-digit Indian mobile numbers)

Guides & documentation

External services

This plugin connects to the Fast2SMS API (https://www.fast2sms.com) to send SMS/WhatsApp messages, send/verify OTPs, fetch your approved templates and read your wallet balance. Your API key and the recipient phone numbers of messages you configure are sent to Fast2SMS for this purpose. See the Fast2SMS privacy policy and terms.
