FAQ
Does this system comply with local anti-spam regulations (like GDPR or POPIA)?
I build the underlying technical features required for compliance, including automated global opt-out logs, "REPLY STOP" unsubscribe webhook handling, and secure, encrypted database storage for user contact lists. However, compliance policies and operational compliance remain your responsibility as
How does the portal manage character limits and concatenated messages?
The backend includes a character counter that automatically splits long text strings according to global telecom standards (160 characters for standard GSM encoding / 70 characters for Unicode/emojis).
Will the portal generate developer API documentation for my clients?
Yes. If you choose the Premium Package, I will build a secure API key management interface. The system will expose clean REST API endpoints (JSON format) so your business clients can easily integrate your custom gateway directly into their own websites and applications.
Can the portal handle automated 2FA and OTP codes instantly?
Yes. I can configure separate routing priorities within the backend system. This ensures critical, time-sensitive transactional traffic—like One-Time Pins (OTPs) and Two-Factor Authentication (2FA) codes—is prioritized over massive promotional campaigns to guarantee instant delivery.
Do you provide the SMS credits or routes with the portal?
No, I provide the software application and API integration logic. You will need to open an account with an SMS aggregator or gateway provider (such as Twilio, Infobip, or Vonage). You will pay them directly for your text delivery credits and message routing fees.
