Guida rapida The AuthSMS API is a JSON REST API. Every request is authenticated with your personal API key, every response is JSON with a `success` flag, and prices are in USD. Use it to automate account verification for WhatsApp, Telegram, Google and 1,000+ other services across 150+ countries.
1 Pick a country
Ask for offers for wa and choose the cheapest country with stock.
GET /offers2 Buy the number
POST the service and country. Keep the returned id and show phone to the user.
POST /numbers3 Wait for the code
Poll GET /numbers/{id} every few seconds until status is received, or let a webhook call you.
GET /numbers/{id}4 Finish
Call complete when you are done, or cancel within the active window if the code never came (auto-refund happens anyway on expiry).
POST /numbers/{id}/completeAutenticazione Create an API key on this page (sign in first). Send it in the X-API-Key header on every request. Keys do not expire; regenerate a key to revoke the old one immediately. Keep the key on your server and never ship it inside a mobile app or browser code.
Chiave API Accedi o crea un account per ottenere una chiave API personale.
curl "https://authsms.net/api/v1/me" -H "X-API-Key: YOUR_API_KEY" Convenzioni
Format JSON request bodies (Content-Type: application/json) and JSON responses.
Success Every response includes success: true. The HTTP status is 200.
Errors Status 4xx/5xx with success: false, a machine-readable error code and a human message.
Money All prices and balances are USD numbers with up to 4 decimals, e.g. 0.42.
Time Timestamps are ISO 8601 in UTC, e.g. 2026-10-16T18:04:11.000Z.
IDs Number and rental ids are 24-character strings. Keep them; they are what you pass back to the API.
Rate limits Per key: 120 reads/min, 12 purchases/min. Over the limit you get 429 RATE_LIMITED. Stati dei numeri waitingNumber is active and no SMS has arrived yet. Poll GET /numbers/{id} or wait for the webhook. receivedAt least one code arrived. code holds the latest one, messages all of them. completedYou marked the number as done. No more SMS will be delivered. cancelledYou cancelled the number; the price was refunded. auto_cancelledNo SMS arrived before the number expired; the price was refunded automatically.
