Add OTP login, checkout OTP verification, 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 order notifications — 25+ events

  • Order placed, pending payment, payment received, processing, on hold, completed, cancelled, refunded, partially refunded, failed and customer notes
  • Shipped, delivered and partially shipped — the statuses set by shipment-tracking plugins
  • Custom order statuses detected automatically: every status registered by your courier or workflow plugin (In Transit, Out for Delivery, RTO, Packed…) gets its own automation with its own template
  • Pending-payment reminder with a pay-now link that cancels itself once the order is paid
  • COD order alerts, one-tap COD OTP verification link to cut RTO, and a COD-to-Prepaid nudge inviting COD customers to pay online
  • Abandoned cart recovery with a configurable delay
  • Review request a set number of days after the order is completed
  • Back-in-stock alerts — customers subscribe on out-of-stock products and are messaged when you restock
  • Welcome message for new customers, and an optional admin copy of every message
  • Admin alerts for new orders, low stock and out-of-stock products

Templates, variables and previews

  • SMS, WhatsApp, or both per event — pick approved DLT / WhatsApp templates straight from your Fast2SMS account with a searchable picker and variable mapping
  • 25+ built-in variables: customer, order, items, totals, coupon, shipping method, pay link, order-status link and more — plus any order meta key as a custom variable (tracking IDs, custom checkout fields)
  • WhatsApp media headers (image, video, PDF) with an auto-generated PDF invoice you can attach with {invoice_url}
  • WhatsApp dynamic URL button variables — templates whose Visit-website button carries a variable are mapped with a dedicated button-variable field
  • Live SMS and WhatsApp phone previews while you configure, and a one-click test send to your own number

OTP everywhere

  • Login with OTP on the WooCommerce login form and wp-login.php, with account creation for new numbers
  • Phone verification on signup/registration
  • Checkout OTP verification: the customer must verify their billing mobile number before the order is placed — works with every payment gateway, box pre-filled with the billing number, your own title and colors
  • One-tap COD order verification after purchase
  • OTP verification on Contact Form 7 ([fast2sms_otp] tag), WPForms and Elementor Pro Forms ([fast2sms_otp_verify])
  • [fast2sms_otp_login] shortcode for any page or page builder
  • Polished OTP screen: masked number (“OTP sent to 98XXXXXX10”), Edit number, resend countdown, light/dark theme, your accent color and corner style
  • Works with Smart OTP on SMS or WhatsApp (with automatic fallback), including OTP templates with extra variables
  • Server-side protection: per-phone and per-IP send limits, attempt caps, OTP expiry and single-use verification tokens

Bulk campaigns

  • Send an approved template to all customers, all users, or a pasted/CSV list — immediately or scheduled
  • Queue-based sending with automatic retries, do-not-send list respected, full logs

Consent, admin alerts and data

  • Opt-in consent checkbox at checkout and a do-not-send list for marketing messages
  • Up to 10 admin numbers for alerts; admin SMS/WhatsApp alert on form submissions; low-balance email alert
  • Wallet balance and SMS count in the dashboard header, 30-day stats
  • Message logs with masked phone numbers, one-click retry and CSV export
  • Phone numbers and API key encrypted at rest (AES-256-GCM), automatic data retention purge, WordPress privacy export/erase support
  • WooCommerce HPOS compatible; instant delivery via a real cron URL or WP-CLI (wp fast2sms worker), with WP-Cron as the fallback

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)

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.
