原文外掛簡介
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.

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.
