Quick Start

Your API key is ready. Two API calls to add OTP verification to your app:

1. POST /otp/send → sends a 6-digit code via SMS 2. POST /otp/verify → checks the code the user entered

See the Integration Guide for copy-paste code.

Integration Guide

Copy and paste this into your project. That's the entire integration.

Step 1: Send OTP when user clicks "Login"

const res = await fetch('https://api.ekukhulenilabs.co.za/otp/send', { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-Api-Key': 'YOUR_API_KEY' }, body: JSON.stringify({ channel: 'sms', recipient: userPhoneNumber, app_name: 'YourApp' }) }); const { otp_id } = await res.json(); // Save otp_id — you need it for step 2

Step 2: Verify the code the user enters

const res = await fetch('https://api.ekukhulenilabs.co.za/otp/verify', { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-Api-Key': 'YOUR_API_KEY' }, body: JSON.stringify({ otp_id: otp_id, code: codeUserEntered }) }); const { verified } = await res.json(); if (verified) { // ✅ Log them in }

Your Frontend — just a text box

<input type="tel" placeholder="Phone number"> <button onclick="sendOTP()">Send Code</button> <input type="text" placeholder="Enter 6-digit code" maxlength="6"> <button onclick="verifyOTP()">Verify</button>

Works with any language — JavaScript, Python, PHP, Java, C#. It's just HTTP calls. We handle code generation, SMS delivery, 5-minute expiry, brute-force protection, and multi-provider failover.

API Key

Your API Key

Include this in every request as the X-Api-Key header.

⚠️ Keep it secret

Never expose your API key in frontend code or public repos. Use it server-side only.
