A WordPress SMS Plugin Built Around Your Gateway
SMPP Center designs and develops WordPress SMS plugins that connect your site to the SMS API you already use, or to the SMPPCenter HTTP and SMPP APIs. OTP, WooCommerce alerts, bulk campaigns, delivery reports, and DLT-ready templates, all from wp-admin.

Get a QuoteWhat the Plugin Can Do
Every module is a first-class wp-admin screen with capability checks, nonce protection, and delivery logs you can audit.
Bulk & Group SMS
Send to lists, roles, or WooCommerce customers. Unicode and GSM-7 length counting, scheduled sends, and per-campaign delivery reports.
OTP & 2FA
Generate, send, and verify one-time passwords for login, checkout, and forms. Rate limits and retry-after windows included.
Order, shipping, and abandoned cart alerts on SMS, WhatsApp, RCS, and voice. Dedicated WooCommerce Plugin with shortcodes and optional admin copies.
DLT Templates
Map WordPress events to approved template IDs and sender IDs. Variable placeholders stay in the registered {#var#} format.
Delivery Reports
Store transaction IDs, pull DLR status, and surface failures in wp-admin. Reconcile unknown timeouts without blind retries.
Webhooks & Hooks
Incoming SMS into WordPress. Outgoing actions via native do_action hooks so other plugins can trigger SMS without forking ours.
Any Documented API, or SMPPCenter From Day One
Most WordPress SMS plugins lock you to one gateway. We build the plugin around your API contract: SMPPCenter, or any documented REST, JSON, XML, or SMPP interface your operator provides.
Bring Your Own SMS API
- API key, Basic, HMAC, or OAuth2 credentials stored in WordPress options
- JSON, form-encoded, or XML payloads
- Custom headers, IP allowlists, and sandbox vs live toggles
- Idempotency keys so timeouts do not double-send
SMPPCenter API
- Sender ID, template ID, and route class in the send form
- Balance and credit checks before large campaigns
- Transaction ID stored against each WordPress event
- Same admin UX whether you start on SMPPCenter or switch later
Built Like a Product, Not a Weekend Snippet
Custom plugins we ship follow WordPress coding standards, VAPT-minded input handling, and a settings model your team can extend.
- Capability-checked admin menus and REST routes
- Sanitized inputs, prepared queries, no raw SQL in controllers
- API secrets stored outside the browser, never logged in full
- WP-CLI commands for bulk backfills when you need them
- Handover docs, staging install, and a changelog on every release
Four Steps From Brief to wp-admin
Brief
API docs, DLT headers, WordPress version, and the events you need to notify. We confirm scope before a line of code.
Design
Admin information architecture, field map, template variables, and error states. You sign off the screens.
Build
Plugin code, gateway adapter, logs, and staging install on your WordPress site or a replica we host.
Launch
Production credentials, test OTP, live DLR check, handover notes, and optional retainership for updates.
India-Ready From the First Send
| Capability | What We Ship |
|---|---|
| DLT template IDs | Every outbound message can carry the approved template and entity ID. |
| Sender ID binding | Admin picks from approved headers. No free-text sender that will fail at the operator. |
| No double-send on timeout | Claim-before-send uniqueness so a slow API does not bill twice. |
