Communication questions.
What is DLT and do I need it?
DLT is the registration framework for business SMS in India. Registered entities, sender IDs and templates are required for transactional, promotional and OTP messages.
What is the difference between transactional and promotional SMS?
Transactional SMS covers service messages such as OTPs and alerts to existing customers. Promotional SMS is marketing content to opted-in audiences and follows separate rules.
Can WhatsApp messages be sent automatically?
Yes. Using the WhatsApp Business platform and approved templates, messages can be triggered automatically by events in your application.
Can I track whether messages were delivered?
Yes. Delivery reports and webhooks provide status for each message, and campaign dashboards summarize performance.
Can I integrate with my own software?
Yes. A REST API with webhooks connects to websites, mobile apps, CRMs, ERPs and payment systems.
