Send OTP SMS

Caution

For security reasons, please contact your Account Manager to provide you with an API host.

The host https://api.example.com not is a real endpoint.

GET

/v2/otp-global/send

• Production

Sends an OTP SMS using query string parameters.

Note: This endpoint generates an OTP code and sends it via SMS. It is not an OTP verification route — use /v2/otp-global/verify for that.

Suitable for quick tests via browser or Postman.

Authorizations

The password is your API key, not your web portal password.

(Where “YOUR_USERNAME_HERE:YOUR_API_TOKEN_HERE” is Base64-encoded)
