Snelstart

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. 1

    Pick a country

    Ask for offers for wa and choose the cheapest country with stock.

    GET/offers
  2. 2

    Buy the number

    POST the service and country. Keep the returned id and show phone to the user.

    POST/numbers
  3. 3

    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. 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}/complete

Authenticatie

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.

API-sleutel

Log in of maak een account aan om een persoonlijke API-sleutel te krijgen.

curl "https://authsms.net/api/v1/me" -H "X-API-Key: YOUR_API_KEY"

Conventies

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.

Webhook-payload en handtekening

Register an HTTPS URL and AuthSMS will POST a JSON event to it the moment an SMS arrives, so you do not have to poll. Each delivery is retried up to 3 times. Verify the signature before trusting the payload.

Gebeurtenissen

  • sms.received

    A code arrived on one of your numbers. data.additional is true for second and later messages.

  • number.cancelled

    The number was cancelled upstream and refunded.

  • number.expired

    The number expired without an SMS and was refunded.

Headers

  • X-AuthSMS-Event

    Event type, e.g. sms.received.

  • X-AuthSMS-Timestamp

    Unix seconds when the event was signed.

  • X-AuthSMS-Signature

    v1= + HMAC-SHA256 of "{timestamp}.{rawBody}" using your webhook secret.
