Question 1

What is a CPaaS Platform?

Accepted Answer

A CPaaS (Communications Platform as a Service) platform provides APIs and infrastructure that allow businesses to embed real-time communication capabilities — such as SMS, WhatsApp, voice calls, and IVR — directly into their applications and workflows. ICPaaS offers a full CPaaS stack deployable on your own server or as a managed cloud service, handling 25 million+ daily API transactions with 99.99% uptime.

Question 2

How does the WhatsApp Business API work?

Accepted Answer

The WhatsApp Business API allows enterprises to send and receive WhatsApp messages at scale using approved message templates. As an official Meta Business Solution Provider (BSP), ICPaaS provides direct API access, template management, chatbot automation, and WhatsApp broadcasting — fully compliant with Meta's policies. Businesses use it for OTP delivery, order updates, customer support, and marketing campaigns.

Question 3

What is DLT registration and compliance in India?

Accepted Answer

DLT (Distributed Ledger Technology) is a mandatory regulatory framework by TRAI for all commercial SMS communications in India. Businesses must register their entity, sender IDs (headers), and message templates on the DLT portal before sending bulk SMS. ICPaaS provides full DLT compliance support including entity registration assistance and DLT-compliant SMS gateways.

Question 4

How can we reduce Cash-on-Delivery (COD) RTO rates?

Accepted Answer

COD RTO (Return to Origin) rates can be significantly reduced using automated order confirmation workflows. ICPaaS enables businesses to send WhatsApp one-tap confirmation messages, IVR outbound calls, and missed call verification to customers immediately after a COD order is placed — confirming delivery intent before dispatch. Mamaearth achieved a 24% reduction in COD RTO losses using ICPaaS's automated IVR confirmation alerts.

Question 5

Does ICPaaS support on-premise deployments?

Accepted Answer

Yes. ICPaaS uniquely supports on-premise CPaaS deployment — the full platform including SMS gateway, WhatsApp API, IVR engine, missed call service, billing, and analytics can be installed and configured on your own server infrastructure, whether on-premise hardware or a private cloud VM. This is ideal for BFSI companies, enterprises with strict data sovereignty requirements, and telecom operators who want full control without recurring SaaS fees.

Question 6

What is the difference between Bulk SMS and WhatsApp API for business?

Accepted Answer

Bulk SMS reaches any mobile number without requiring the recipient to have any app installed — ideal for OTP, transactional alerts, and promotional campaigns with wide reach. WhatsApp Business API provides rich messaging (images, buttons, documents) but requires WhatsApp to be installed. WhatsApp typically achieves 98% open rates vs 30–40% for SMS. ICPaaS supports both channels on a single unified platform.

Question 7

How long does it take to integrate ICPaaS into my application?

Accepted Answer

ICPaaS provides developer-friendly REST APIs with production-ready SDKs for Node.js, Python, PHP, and Java, plus Postman documentation for fast testing. Most developers complete a basic SMS or WhatsApp API integration within 30 minutes. The no-code drag-and-drop IVR builder and webhook engine allow non-technical teams to set up complex workflows without engineering support.
