Migrate from Twilio Verify

Two calls become two calls. The main differences: no Verify Service to create, no phone number to buy, and you're billed only when a code actually verifies.

Send a code

// Twilio
await twilio.verify.v2.services(SERVICE_SID)
  .verifications.create({ to: phone, channel: 'sms' });

// Delivered
await fetch('https://api.deliveredsms.com/v1/verify', {
  method: 'POST',
  headers: { Authorization: `Bearer ${process.env.DELIVERED_API_KEY}`, 'Content-Type': 'application/json' },
  body: JSON.stringify({ to: phone }),
});

Check a code

// Twilio
const check = await twilio.verify.v2.services(SERVICE_SID)
  .verificationChecks.create({ to: phone, code });
if (check.status === 'approved') { /* ... */ }

// Delivered
const res = await fetch('https://api.deliveredsms.com/v1/verify/check', {
  method: 'POST',
  headers: { Authorization: `Bearer ${process.env.DELIVERED_API_KEY}`, 'Content-Type': 'application/json' },
  body: JSON.stringify({ to: phone, code }),
});
const { verified } = await res.json();
if (verified) { /* ... */ }

What maps to what

Things that get simpler

• No Verify Service. Delete the VA... SID from your config.
• No number. Delete the number provisioning step entirely.
• Billing follows success. Twilio charges per verification attempt; we charge when verified comes back true, so pumping attacks and abandoned signups cost you nothing.
• Attempt/expiry state is in the response. attempts_remaining and expires_in let you render "2 tries left" and a countdown without tracking anything yourself.

Things to watch

• US and Canada only right now. If you verify internationally, keep Twilio for those routes or talk to us.
• We do not have SDKs yet — the examples above are plain fetch, which is the whole integration.
• Sandbox has no resend cooldown so you can iterate; live enforces 60 seconds per number.
