Example technical integration Below is a high-level description of a typical integration pattern using the SureSMS gateway: 1. A customer application collects a verified mobile phone number from a user during signup or login. 2. The backend system calls the SureSMS API with authentication credentials, recipient number, sender ID, and message content (e.g., a one-time password).[web:8][web:11] 3. The SureSMS gateway delivers the SMS to the mobile network and returns a message ID or status code to the customer system.[web:5][web:8] 4. The customer system periodically or asynchronously queries status / delivery reports (via callbacks or API calls) to update message state and user flows.[web:5][web:8] This pattern can be applied to OTP flows, alerts, marketing campaigns, and many other SMS-driven use cases.[web:8][web:14] ## 9.
