Voice OTP for React

Send a Voice OTP from React

Never put the API key in the app. The app calls your backend, and your backend calls Edesy (see the Node.js or Python example).

// In your React app: ask YOUR backend to send the OTP
async function requestVoiceOtp(phone) {
  const res = await fetch("/api/otp/voice", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ phone }),
  });
  if (!res.ok) throw new Error("Could not send OTP");
}

// Your backend route (/api/otp/voice) then calls
// POST https://voice-api.edesy.in/v1/voice-otp/send with the API key - see the Node.js example.

The result arrives on your webhook

Status is one of delivered, no-answer, busy or failed. dtmf_response is set when you enable press-1 confirmation.
