SOLUTIONS / TECHNOLOGY & SAAS

Build SMS into your product with an NZ messaging partner.

Add verification codes and customer messaging through the TNZ API. Use SubAccounts to separate customer activity and costs, with NZ support when you need help integrating.

Start with SMS. Add email, WhatsApp and voice through the same account as your product grows.

What will it take to connect your application?

Call the REST API directly or use a library for your language. The work depends on how your application triggers messages and handles the results.

  1. Choose your connection

    Use REST, .NET, Python or Node.js/TypeScript. For software that already sends email, consider Email-to-SMS.

  2. Connect sending and replies

    Supply the destination and message, then configure delivery results and incoming replies. Decide how your application will handle each event.

  3. Test before sending to customers

    Check message delivery, replies and failure handling with your team. The SMS API also has a Test mode for processing requests without a live send.

Choose a use case for API details, channel options and integration guides.

Deliver verification codes

Send your application's one-time codes by SMS, with voice delivery when needed. Your application controls the verification process.

Connect WhatsApp conversations

Send approved WhatsApp templates and receive customer replies through the API. Configure SMS fallback if WhatsApp delivery fails.

Send monitoring alerts

Connect alerts from your monitoring software by API or Email-to-SMS. Your monitoring system decides who needs the notification.

Keep each customer's messaging and costs separate

Use SubAccounts to organise activity by customer. For SaaS providers and agencies, this gives you a way to allocate usage and prepare customer charges.

Delivery webhooks include the message price. Your billing workflow can use that data alongside monthly reports to reconcile costs.

Moving from an overseas provider?

Start with one message workflow. Map your current authentication, request fields and delivery callbacks to TNZ, then test the sending number and replies.

Compare local short-code access, NZD pricing and reporting alongside the API work. TNZ provides fast delivery and an NZ support team for integration questions.

James Dunlop Textiles

Connect messaging to an existing business system

James Dunlop Textiles needed better customer emails from its existing ERP. TNZ built a file processor to convert the ERP output into branded emails and deliver them through its cloud email service.

The published story reports that emails going to spam fell from approximately 10% to under 1% for this project.

SMS Sending Numbers

Built-In Short Codes

When you send SMS in New Zealand, your messages come from a TNZ Short Code, a 4-digit number like 3003. One is assigned to you automatically based on your message type. It's instant and included in your plan.

Most businesses start here. Built-in Short Codes work well for appointment reminders, alerts, and general business messaging, with no setup required.

Dedicated Short Codes

If you're running keyword campaigns (e.g. "Text INFO to 3003"), want full inbound SMS from any NZ mobile, or are building long-term brand recognition, a Dedicated Short Code gives you exclusive ownership of your number.
