Service 04

Reach people where they already are — WhatsApp, SMS, voice.

We connect the official WhatsApp Business Platform Cloud API with DLT-registered bulk SMS and voice, so promotions, alerts, and transactional messages land at campaign scale — with delivery visibility and compliant consent handling.

Messaging is still the shortest path to a phone. Email gets filtered, social gets throttled, but a WhatsApp template message from a verified business number gets opened. We help you set up the official API properly — number registration, business verification, template approval, and integration into your site, CRM, or campaign workflow.

Strategy matters as much as plumbing. Template wording, consent capture, send timing, frequency caps, and opt-out handling decide whether a campaign performs or burns the list you spent years building.

What we deliver

  • WhatsApp Business Platform Cloud API setup, verification, and template approval
  • Integration with your website, CRM, or internal systems
  • Promotional and transactional bulk SMS on DLT-registered headers and templates
  • Voice blast campaigns where voice outperforms text
  • Scheduling, multi-language sends, and delivery status reporting
  • Consent capture and opt-out flows that keep you on the right side of the rules

Who this is for

Real estate teams announcing launches, political campaigns coordinating voters and volunteers, educational institutes running admissions cycles, and businesses that need reliable transactional and conversational messaging at volume.

Compliance

Messaging in India must follow TRAI regulations, including DLT registration of sender headers and content templates for SMS. WhatsApp engagements additionally follow Meta platform policy and your BSP's terms. We set this up correctly rather than routing around it, because grey-market messaging gets numbers banned. See our Messaging Terms for full service usage policies.

FAQ

WhatsApp & SMS questions, answered.

What is the WhatsApp Business API and how is it different from the app?

The WhatsApp Business app is for small teams messaging manually from a phone. The WhatsApp Business Platform Cloud API is the official programmatic channel for sending template messages at scale, running automated flows, and connecting WhatsApp to your CRM or website. It requires business verification and approved message templates.

What is DLT registration and do I need it for bulk SMS?

DLT is the Distributed Ledger Technology platform mandated by TRAI in India. Any business sending commercial SMS must register its entity, sender headers, and content templates on a DLT portal. We handle this registration as part of onboarding — without it, messages are blocked by operators.

Can you integrate WhatsApp with our website or CRM?

Yes. We connect the API to your existing systems so enquiries, order updates, appointment reminders, and campaign messages flow automatically, and so replies land somewhere your team actually monitors. We can also pair this with an AI agent for first-line qualification.
