Our delivery webhooks are signed with Standard Webhooks v1.
So you verify us with an off-the-shelf library in a few lines, not a signature scheme we made up. Delivered, sent, read or failed, pushed to your endpoint as it happens.

Where Meta won't deliver WhatsApp auth codes, our API says no before it sends.
You get a 400 that names the country and tells you to use SMS for that number. No message goes out, so there's nothing to pay for a code nobody receives.
myotp.app
Users double-tap "Send code". That second tap shouldn't cost you a second message.
MyOTP answers a repeat send to the same number with a 409 while the first code is still live. One code, one charge. Need a real resend? Pass force_send.
15 free codes: myotp.app
Your users should see your name on the code, not ours.

Five wrong guesses and the code is gone.
MyOTP deletes a code on the fifth wrong try, so nobody can walk a short code by trial and error. The next attempt needs a fresh send.
It's on for every plan. Nothing to configure, nothing extra to pay.
An SMS OTP on MyOTP costs 1 to 63 credits, depending on the country. A Telegram OTP costs 1 credit in every country on our price list.
If your users have Telegram, every code costs what the cheapest SMS route does. Same API call, channel set to telegram.
