Overview
GetOTP lets you add one-time password (OTP) verification to your app via SMS, email, or WhatsApp with a few API calls. You trigger an OTP send with one request and verify the code the user enters with another. It removes the complexity of building OTP delivery infrastructure yourself and supports multiple countries.
Beginner Tip
Sign up at https://otp.dev to get your API key and pick a delivery channel (email is easiest to test). The flow is always: POST /otp/send to send the code, then POST /otp/verify with the code the user enters.

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://otp.dev/api/v1/otp/send";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
headers: {
"X-API-Key": "YOUR_API_KEY"
}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
